Look Ma, no hands!

As kids in Sonoma, we’d try riding bikes with no hands on the bars all the way down Denmark street. It helped if the tires were pumped up firm and your core was tuned up (from pulling weeds). Fast forward a few decades, and Charlie’s demonstrating what we finally got right with the rudder balancing! We’ll do some by-millimeters shim adjustments on the water this weekend to bring back just a touch of weather helm, then take the cassette home one more time for bonding in the new part. Phew.

Also in that photo note the radar is missing. The stern tower is working out great, but the radar was too low. Joe the electronics guy immediately scoffed, noting the radar beams that would hit us in the cockpit. So it’s getting a 4′ extension pole made from VA Bob’s windsurfer mast offcut he kindly sent over. img_3870

That’s the top plate, sitting on the table a few evenings back. Tonight we bonded on the lower disk that will bolt on the tower where the radar used to mount. The top plate has an extra lip on the front to mount a couple of LED deck lights.

The jib deck bag got it’s final sewing job; recall that it didn’t quite button up around the forestay because someone (the builder) didn’t allow for enough sail bulk up there. So it got these earflap looking things:

and now it’s fine. We’re happy with the open mesh bottom, especially now that it’s been raining and this is free to drain.

Electricity supply in the boat is still the tiny lawnmower battery, but we’ve finally called-the-ball to begin the Lithium Iron Phosphate battery pack build. The order went to EVtv.com, an electric-car conversion company in MO. This topic is extensive, and a lot of people are interested in just this, so we’ll do some dedicated posts coming up on the battery system install. For now, it’s the physical challenge of mounting the 16 cells in a spot that was originally built for just a couple of car batteries. This tray mold was done based on dimensions provided by the battery dealer, before the crate arrived.

img_3834img_3838

And yesterday just before closing time, UPS Freight called to say our crate had arrived at their dock. Y’all can guess what Greg got for Christmas this year!

img_3871img_3872

Took two of these blue cells and the tray to the boat last night, and it’s not going to fit standing up as planned – just not enough clearance on top for the wiring. But it’ll work with the tray tilted back about 40 degrees, with the battery back edges resting against the curve of the hull. So tonight was also some surgery to trim away the front of the tray and add height to the back side for this new mounting configuration. That’s enough to whet your appetite on LiFePo4…

Now, back to that sail the other day with Charlie smiling. After five months in the water, I FINALLY got an actual performance sail-tuning, get to know the rig day! Carlos was aboard, and it was a joy to get F27 Papillon captain Drew Scott out for the first time. Drew is a talented racing sailor with an intense eye for sail trim, and I really needed to get him aboard to help assess this new boat, new mast, new sails combo. we’re all in love with this big, powerful, easily adjusted main (and so far the Leneman Vee mainsheet / no traveler hardware ROCKS!)  The Hydranet fabric (spectra & dacron weave) is holding shape like a fixed wing.

img_3856

The jib had been sailed reefed through the summer and fall because of high winds and the mast & steering issues we were sorting out. So here was it’s first real use day. We’ll start with Inspector Scott checking things out.

img_3859

The sail appears to be cut to allow for a big full belly in light winds.

img_3848

I’m concerned the transverse mounted cars aren’t far enough aft for this size sail. Here are the light wind shots (around 5 kts as we were leaving the Richmond breakwater area)

img_3850img_3851img_3853

In the third photo, as we start to point higher, the sail is rubbing on the upper diamond wire. A half hour later we’re out in the main bay, with wind up in the 10-12kt range.

img_3863img_3865

The headstay tension is light and it’s bending off to leeward, which helped keep the sail off the diamond wire, but that’s not a real solution. The second shot shows the effect of the jib car placement – the sail is not balanced top to bottom in terms of airflow. So we tried various temporary sheeting angles to get the sail drawing equally at each set of telltales. img_3866img_3867 In retrospect, I’ve realized there’s more overlap of the mast with this sail than I had wanted, and we have to solve for the diamond wire interference. Hopefully we’ll be able to solve this with local support, rather than the jib having to travel cross country again. Stay tuned.

CALL FOR CREW = local folks, would you like to sail Ravenswing this Sunday?  Weather forecast is down to 20% chance of rain, and 10kts of wind from the west. We’ll aim for a late morning start. Please call, text or reply back here if interested. 707.486.3954

You wanna be like this guy. He knows the drill :)

No hairdryers please

Part of the ‘keeping it simple’ plan is to skip power-hungry appliances and a big inverter to go from the boat batteries to 110volt household circuits. So we’ve kept shore power completely separate from the 12volt system, including its own mini panel in the equipment room.

First we bring a 30amp cable to the boat, with the plug just ahead of the aft beam, in the port cockpit coaming.

20160206-221837.jpg
These new cords have clamping jaws instead of the old spinning rings. Plus a handy flashlight to help with night maneuvers.

20160206-221958.jpg
Next was running a 10awg/3wire conductor in plastic conduit thru the coaming box, the lazarette and down into the equip room.

20160206-222155.jpg

20160206-222219.jpg
You can see the pass-thrus for water and diesel in front of the conduit; they will get hoses that run just like the electrical path.
The 110volt panel has built in ELCI. This is the next step beyond GFI ground fault interruption. See the ELCI components – the black ring – on the back.

20160206-222629.jpg
This thing will shut everything down in milliseconds with any problems of the incoming juice, bad grounds, wires in the surrounding water, etc. And it all comes pre-wired with these BlueSea panels.
We screwed the panel in place and plugged in – the system did its job and warned of a reverse polarity problem in one of the workshop’s power outlets. We moved the cord and got all green (good) lights.

20160206-223023.jpg

20160206-223041.jpg
Just two branch circuits – one for the battery charger which will mount close by, and a second for two household plugs (one in photo and another in galley). That’s it, but could be expanded later if needed.
This finished the primary wiring job. There are follow up items – more light fixtures are coming this week as the galley, equipment room and over the dinette weren’t bright enough with the original purchased fixtures. And we still have all the wiring inside the stern tower to run, after the exterior paint job.
All of the smaller wire terminals were applied with a new ratcheting precise-fit crimper. Anyone doing 12volt work should get the positive-stop ratcheting tool. But with the heat shrink fittings you need a single-crimp jaw. I couldn’t find a single-style under $75, so we bought the more common double crimp for $25 delivered free from Amazon.

20160206-223840.jpg
Made sure it had removable jaws, so they could be popped out and hit with the grinder, throwing big sparks all over. A few minutes later we had single-crimp capability that didn’t mar the heat shrink portion of the terminals.

20160206-224041.jpg
With the wiring done we’re attacking the finishes needed inside the toilet and shower compartments. In a moment of clarity we decided to return to Leneman’s original suggestion of a below-the-waterline sewer tank drain (at sea only), which drastically simplifies the toilet plumbing runs, including closing up some previously made bulkhead and cabinet holes. This also finalized the thru-hulls locations, so that’ll be the next posting for you.

It’s alive!

Honey, why are your hands so dry and scratchy?, she asked. Might have something to do with using this about two hundred times this week.

20160129-232818.jpg
So a few hours after burning the prints off one finger (don’t grab for the heat gun without looking Greg!) the last lamps and pumps were connected and it was time for the moment of wiring truth. But first we needed juice. A visit to the Winglet (travel trailer you saw here two months back) to borrow the battery and it’s ready to throw the main switch.

20160129-233334.jpg
And just like that, 50 or so hours of wiring paid off.

20160129-233429.jpg

20160129-233449.jpg

20160129-233512.jpg

20160129-233530.jpg
Everything works as it should, including the two ‘big ticket’ items currently installed, the refrigerator and the windlass. We’ll detail those with more pictures soon. It was very satisfying to stand in the cockpit by the remote switch and make the windlass go up and down! The boat is coming to life.

The wiring plan includes AWG 2 size conductor for the battery-to-panel runs and the windlass circuit. There’s a 100amp fuse between the battery and the panel. The windlass has its own 70amp breaker and a direct cable to the battery switch. All of the branch circuits from the panel, plus the direct-to-battery bilge pump circuit, are AWG 12. That’s a bit of overkill for some of the lower draw circuits but overall it’s safer and was easier to pull everything from one 500′ roll. There’s about a dozen feet left (the very rough calcs did the trick). The 12/2 cable presented a challenge, as most terminals for stringing small lights etc. don’t deal with that big wire. A new item in the Ancor electrics line became the mainstay of the lighting system.

20160129-234927.jpg
They are sized for one input wire and a pair out, so these allow pigtails, or highway off ramps, down to individual light fixtures. Not cheap at about $1.75 each, but it seems bulletproof for a long time.

20160129-235204.jpg

And for Cap’t Holway, I am eager to show you how EVERY wire on the boat is easily traceable and accessible beyond covers and dedicated chases.

Here’s the back of the main panel now fully loaded. BlueSea’s product is great, although I made it all more challenging by mounting on a swinging door. It was tricky sizing each conductor to do a proper loop or bend for opening / closing. There were many hours fiddling around in here…

20160129-235640.jpg

20160129-235657.jpg
The small black box on the left is a sub / fuse panel just for the electronics branch circuit. The 15amp feed and return are the top and bottom wires that go to breaker #11 on the panel. Then this distribution box allows each electronic item to get its own size fuse. E.g. VHF has a 7amp, propane sniffer has a 0.5amp

Some people don’t like the LED lighting for a boat. But low power consumption, less generation worry and less battery weight is the goal for sailing fast. Tonight we switched on a bunch of the LEDs plus the radio – look at the ammeter in the panel barely registering an amp. A very good start!

20160130-000358.jpg

Best wishes for dry skies and crisp breeze to all our friends in tomorrow’s Three Bridge Fiasco. Looks like America’s biggest sailboat race has hit another entries high this year. Have fun guys!

Crimp my style

Throughout wiring the boat we’re guarding against voltage drop – the problem when too small of a wire gauge impedes the juice by excess resistance (heat, if bad). The anchor windlass has a big motor under heavy load pulling spikes of 50 amps so it needs a big thick cable run back to the batteries. BlueSea electrics, and many others, provide handy wire sizing charts based on electrical load and distance. Our windlass circuit is about 50′ out and back, times the 50 amps = 2500 ‘ampfeet’ on the chart, pointing to AWG 2 conductor wire. That’s also the appropriate size for the 15′ circuit from the batteries to the 100 amp main circuit breaker panel. So with about 35′ each of red and black AWG 2, we got busy cutting and crimping.

20160123-230230.jpg

20160123-230303.jpg
After fretting over who to bug for big lug crimpers, we finally remembered squirreling away these swaging clamps, and they do a great job with the cable lugs. These two 23′ cables for the windlass added another 7 or 8 lbs to the boat.

20160123-230738.jpg
Then we have a number of runs between batteries, ammeter shunt, main fuse, the panel, etc. Some of those in process:

20160123-230911.jpg

20160123-230935.jpg
Overall the wiring is clipping right along, except that back orders on the many sizes of various fittings are causing lots of stalls. All in good time I suppose. The nav station is coming together with the VHF, the propane controller, a USB port and a cig-lighter style port. The battery switch and windlass breaker got some of those big red jumper cables shown above.

20160123-231436.jpg

20160123-231455.jpg
Up on the bow we trial fit the windlass foot switches, which have waterproof housings around their wires, protruding below deck. So they need a pass-thru. Bonding in tubes is a great way to go. These are cheap carbonfiber pieces from Tap Plastics. If the hole is for bolts, use G10 glass tubes for strength.

20160123-231826.jpg

20160123-231845.jpg

20160123-231902.jpg
We’ll show you the windlass switch wiring after the deck is painted and we come back for the final install.
Tomorrow we’ll continue with interior lighting.

Here are hundreds of cell phone lights behind Bruce Springsteen on Tuesday night in Chicago as he sang a tribute farewell to Glenn Fry. We were taking bets on what he’d pick. I won – ” Take It Easy”. Standin in a corner in Winslow Arizona, such a fine site to see, it’s a girl my Lord in a flatbed Ford, slowing down to take a look at me… (You can take it from there :)

20160123-232855.jpg

Reds and yellows

American Boat & Yacht Council (ABYC) electrical standards call for 12volt positive + feeds to use red cable and negative returns – to use yellow. That’s what’s inside the 500′ spool of 12AWG we saw a few posts back. With the right ‘terminators’ in hand (the rings MUST be sized to fit the bolts they slip over, and we have 5 different bolt sizes in the system!), we attacked the panel on Thursday night. Here is 7:30pm

20160116-075202.jpg
And 10:30pm…

20160116-075303.jpg
Then after another hour Friday eve of clipping the casings, adding zip ties and aligning the bundle for door swing

20160116-075506.jpg
The board glued inside that cabinet today will get a distributor block for all things in the nav station, plus the panel feed cable shunt (which provides the ammeter reading). Last night we also cut the big 2AWG battery cables to feed the panel and return to the batteries, service the main fuse and the windlass needs. Altogether it’s about two dozen lugs that need heavy duty crimpers which we’ll try to rent or borrow. We’ll show you all the primary feed wiring once those lugs are solved.

Returning from an East Bay business meeting, I was fortunate to catch Bay Area Multihull Association veteran Bill Roberts at his amazing new boat that just arrived in Richmond.

20160116-080415.jpg

20160116-080433.jpg
Bill has a great story finding this barely-used but INCREDIBLY outfitted luxury performance Dragonfly 1200 tri in Canada thru Gary Helm’s brokerage. The quality of the Quoring group’s fit and finish looks superb, and the Roberts family gets to enjoy high end carpentry, still-unused appliances and bunks, forced air furnace, etc. (did you catch the bow thruster?) Bill and the Bay Marine staff will hustle to step the 65′ (!!!) mast, lace the nets, and bring all systems out of winterized mode in time for Three Bridge Fiasco day. BAMA folks, it’ll be hard to miss this blue beauty out there. For me it’s fascinating to look at the different design approaches: this 1200 looks like it will power through any seas with authority, sailing fast and carrying a sense of beefy security (big Volvo 4cyl diesel, substantial SS fittings, etc). Our F36 is the same length and a bit wider, but only 40% of the total weight, “Spartanly” finished and a 15′ shorter rig. Should be very interesting to sail and cruise these two side by side.

Ok, back to the wiring tools for a rainy NorCal weekend.

Between the decks

So, we’ve reported on the hull exterior & deck being ‘done’, and you’ve seen the painted & trimmed interior. But there’s a bit more fabrication of ‘the spaces in between’. This weekend we tackled deck fills for water and diesel, through the cockpit coaming box and lazarette, to the equipment room. We’ll use flexible pipes between the deck fills and solid fiberglass tubes that bisect the tops and bottoms of lockers. The Forespar marelon deck fills are 1.5″ OD. 1″ sched 40 PVC wrapped about ten times in lightweight glass cloth gets to exactly 1.5″:

20160110-205255.jpg

20160110-205312.jpg

20160110-205330.jpg
The pipe was coated in good mold release wax, so a few hammer taps on a big screwdriver popped it out

20160110-205519.jpg

20160110-205543.jpg
The diesel and water deck pass throughs are on the left, and the grey curve is a trial fit of PVC conduit that will carry the 110v shore power to the inlet on the right.

The lazarette currently has the main cockpit drain entering and exiting its aft edge.

20160110-205847.jpg

20160110-205909.jpg
That needs a dedicated drain tube, especially since the propane well was added in this compartment. And there’s already a second overboard drain for the lazarette on its forward hull edge. So here’s a simple 90degree form with non-stick tape and peel ply laid in before the glass channel is made.

20160111-223906.jpg

20160111-223929.jpg
And the new piece tabbed in place.

20160111-224027.jpg
It looks like the diesel Espar heater will exhaust through the hull up high in this area so we’ll wait in placing the second half of the diesel and water filler pipe pass through tubes until the exhaust pipe is in place.

Random segue over to wood finishes: we’re happy with the transparent non skid that was added to the sole (floorboard) panels a couple months back. But that was added to a floor-finishers polyurethane that came out too yellow. The companionway sills and steps needed non skid yet we don’t want to cover the woodwork with the standard tape. So here they are redone in Interlux Perfection topsides paint with zero pigment (labeled simply Clear) and a heavy dose of non skid powder.

20160111-224956.jpg

20160111-225010.jpg Very happy with the results.

And while we await that big box of electrical parts, we’ve finished up cable runs and installed most of the cabin lights. There are two halogen map lights, and everything else is LED. There’s a bit of angst about turning on all these lamps for the first time in place – really don’t want it to be the sterile, operating room blue-white look. The catalog copy and packaging has lots of “warm, soothing” descriptors but the old marketing hand here says “we’ll see”.

20160111-225619.jpg

20160111-225634.jpg
Hopefully usps will deliver and we’ll dive in to 100’s of crimps and heat shrinks over the next few evenings.

It all started when we looked at the map…

The F36 building plans are pretty succinct about wiring the boat for electrical service – get a qualified electrician. We bought time with a marine electronics planner to do overall schematic and equipment selection work. But in the spirit of truly knowing one’s own boat, like everything else so far it’s bear down, learn it and go for it. After numerous sketches and notes over months, a circuits plan got down on paper to match the 18-breakers slot BlueSea panel.

20160107-214038.jpg
The diagram has 14 twelve volt branch circuits from the 100amp panel, a 70amp dedicated service up to the windlass and a bilge pump circuit with 10amp fuse wired to the battery switch. Additional cabling runs handle the remote windlass switch, the propane danger sniffer, VHF antenna, radar cables and sailing instruments. Primary wiring chases are on the starboard side of the boat.
Detail hounds will note the mast isn’t even mentioned; Keith will be happy to hear all wiring was stripped during the mast refit. VHF and anchor light and deck lights are on the stern tower. Steaming light will be near the bow.

The 110volt system will be completely separate, with its panel in the equipment room and cabling along the port side of the hull. We’ll see that next week.

First up was preparing spaces. All bulkhead pass throughs got PVC liners. These helped the cables slide thru like little greased pigs!

20160107-215030.jpg

20160107-215108.jpg</a
Then a scramble when we realized the electric cabinet face hadn't quite been finished before the holidays:

20160107-215230.jpg
Then uncover dusty boxes to bring up on deck the goodies we’d stashed under work tables. That’s a 500′ spool of 12AWG cable. (How could the boat possibly take 500′?! Hold that thought…)

20160107-215722.jpg
We set the spool up on a spinning pole in the cockpit and started pulling. Probably the smartest trick done on the boat in 2015 was writing directly on the cable cover with an ink pen every 3′ as it came off the spool which circuit number we were snaking through the boat. The entire afternoon of laying in 18 cable runs had zero confusion about what was what as you can see the branch circuit numbers everywhere. Here’s 1a, the forward running lights on their way.

20160107-220226.jpg
And this is about four hours later

20160107-220307.jpg

20160107-220345.jpg
Late on Sunday we had run out of large-bore PVC bulkhead liners and decided to keep wiring anyway. So a few days later some backtracking pulled that bundle of cables backwards and through the piece that still had to get cemented in place.

20160107-220917.jpg
The panel slid home nicely, up above the chart desk.

20160107-221240.jpg
Not going to show the panel back yet because the cables aren’t connected; there’s a big box of many sizes needed of various cable end terminators / connectors coming from Defender. That’ll be weekend fun. Meanwhile there are lots of components that need installation now that we can see placements dictated by sensible cable routes. Here are the main battery switch and windlass circuit breaker / cutoff placed under the sea berth just forward of the chart table.

20160107-221857.jpg
While we wait for that box of 300-ish various connectors we’re doing similar prep work on plumbing. And watching the skies for signs of painting season. Still too much rain for that now…

By the way, 450′ of that spool have been swallowed up.
