Dan, do the holes under the splash well drain to the bilge?  It almost looks like a tube through to the transom on the starboard side unless its light playing a trick on my eyes.

Todd, I'm not following you perfectly. The scuppers that drain the entire back deck go through the lockers on each side via fiberglass tubes, and out the transom to drain outside the boat. The splashwell has 2 scuppers the drain outside the boat. Does that answer your question?

Yes.  You answered my question.  Im interested in how they work for you.  I plan to do something like you have.  Have you thought of a name for your boat?

Brian - the wiper system is all manufactured by Roca, distributed by Imtra. Regular radial wipers on such small windows will only remove a small amount of material, so to be effective you're really pushed toward the pantograph style. I notice Bayweld is using Roca gear on their boats, and Dave from Heavy Weather Boats is sold on them too, won't touch anything else.

Thanks, Dan ... I will stick with Roca if I ever build a big boat again!

Dennis - Anthony (of Cook Inlet Boats, who did my marine carpentry) broadcast medium lag sand over fresh paint, and once that dried, painted a couple more coats, or something along those lines. He did a test on KiwiGrip, which I was pretty excited about, and said it was a joke. Anthony is pretty conservative about the non-skid, as I'm inclined to be out early on ski trips or late on hunting trips, and ice on deck is a real possibility, so non-skid has to be a bit more aggressive than it would be otherwise. After more thought, and seeing the results, I agree. Slipping off the boat is a very poor option up here.
<snip>

My worst slippery deck experience was on someone ELSE's boat ... a fiberglass one.  He'd washed out the cockpit with dish soap and water ... but didn't rinse well.  It was fine when the deck was dry on the way out, but the weather and seas got really rough and we got a lot of spray in the boat ... which turned the residual soap into DECK LUBE... I nearly broke my ankle, got nasty bruises all around my shins, fell several times in spite of trying to hang on and move carefully.  Needless to say, fiberlgass is slippery and his 'poser' imprinted deck was NOT anti-skid.  Bad juju!  LESSON: Wash your boat out with AMMONIA water, let dry, spray down with Chlorox water to disinfect.  Done.  Do NOT use SOAP!!

Fair enough, no soap.

And here is the question about name again........nothing has struck me yet. It will come in time. Might have to take it out a couple times and get it into its natural habitat for a name to appear. Doesn't look very happy sitting on a boat trailer.....

That's the best way ... let the boat inspire the name.  You don't want to name it after a person or you may end up like Jim O'Meara ... who had a wife named Kim.  He named his boat the Kim-O .... then they got divorced ... the he had to change the 'K' to a 'J' and his boat became the Jim-O  :D

"Dr. Seuss" came up as a possible boat name, and I always loved his books so got a kick out of that. Imagine the call on the radio.....

Meanwhile, I'm approaching completion of my main electrical design. This is all in place already minus a few fuses, the battery monitor, solar system, and accessory fuse panel near the panel. Getting it all down in good detail ironed out some misunderstandings I had and revealed a few places I still needed fuses. Excellent exercise, plus when finalized this is getting laminated and screwed inside my aft electrical cabinet door.

Still debating the pot puller, really want to get the Electrodyne and never look back, but it's awfully big. Might be OK with a Discovery Bay model on a custom davit coming out of my aft SB cabinet. The Saf-T-Pullers and related are having production problems I'm told, and I just don't like the looks of them anyway. I do want to pull all 4 pots in one go and get on with things, so the maybe I've gone to all the trouble to make the boat light so I can buy a big hauler.....

A day of going backwards to bond the fuel fill fittings and fuel tanks. Bonding these items is both required by code and makes perfectly good common sense. I've heard the call on the radio about someone's boat catching on fire, and I'm trying to avoid that through careful wiring.

Carefully found the underfloor sub-stringers with a stud-finder and measurements, successfully hole-sawed into each tank compartment, tapped the supporting lip of the tank without hitting wood or the tank, and bonded the tanks using a 1/4" bolt and #12 wire, using conductive grease just to be on the safe side, and 2 layers of heat shrink wherever the wire went through a bulkhead. Mixed up some thick epoxy and used just enough to get the plug to stick, trying to avoid dripping any epoxy onto the tank and wires. I'll fill the remaining gaps and center holes tomorrow, and eventually smooth it all out and touch it up with the deck paint. Good enough, very happy to be done with this unhappy job.

For the fuel fill, I took out one of the screws, used a long bolt, and set it with conductive grease rather than a dab of sealant so as to repel water while still getting good electrical conduction between the bolt and tank fill. Bonded the bottom of the bolt and ran it back to the bonding/grounding bus.

With all this back-work done, I anticipate some serious forward progress in the next couple weeks. Mostly electrical and electronics. Just keep drilling holes in the boat, eventually it will get done!

Better safe than sorry!  Bonding (keeping everything at ground potential) also helps prevent corrosion.  Even though these boats are wood and glass, not metal, it's worthwhile to own and read Nigel Warren's book, Metal Corrosion in Boats too.

Finished all the major/large wiring today. Now time for the fussy cabin/panel wiring, nav lights, and electronics.

House battery with fuses directly from the battery post, so every inch of every positive wire is protected. In the house battery box is the smart shunt for the Balmar SG200 battery monitor, which is brand new on the market and *far* better than any other battery monitor I've found, in addition to being small and relatively affordable.

Common neutral/ground/bonding bus in aft starboard cabinet before and after putting the protective covers in place. I decided not to invest in crimping tools for wire larger than #8, because I envisioned several spools of large gauge expensive wire left over that I didn't want to have to store and maybe never use. I'm happy with that choice, especially since I have Polar Wire within 10 minutes of the boat shop - they make up large, quality cables on the spot at a very reasonable cost with high quality terminals (they're also THE place in Anchorage to buy wire and heat-shrink terminals). That said, looking at this picture makes me wish I had the tools because I could have tidied things up a bit and done better labeling. Oh well, it's functional and doesn't need to be an art project.
 
Aft port cabinet has start battery, 2.5 gal diesel tank for Wallas heater, and bilge switch. There will be zero fuel stored inside the cabin.

Shallow aft center "cabinet" over the bilge has the battery combiner switch, again with any necessary fuses mounted directly on the post so any smaller wires branching from larger incoming wires are completely fuse-protected. Makes it look like a Frankenstein switch but again it's very functional and efficient as far as wiring goes. Also have my battery to battery charger, which smart charges the house battery (AGM batteries are fussy about charge voltages) whenever the alternator is charging the start battery. The start battery is only charged from the alternators, which are not smart and thus I imagine the start battery may not last quite as long because there's no good way to implement smart charging to the start battery on an outboard boat - after a few hundred hours of research and trial and error I found that out....

That looks like a lot of work.  Did You stick to the schematic above.  I may steal it if you end up entire pleased with it.

Todd, yes, I've stuck to the wiring diagram above with some tweaks to the kicker steering, which is a Panther Products T-5 steering system. I don't have a lot of data on anyone with Tolmans or GAs using it, so I figure it's still a bit of a hopeful experiment, but looks promising.

I think this diagram could work, or at least be the basis for other GAs.....only each individual is obviously responsible for their own wire and circuit protection sizing. That said, there are a lot of other ways to wire the boat. For instance, some may want the bilge switch somewhere else, or may choose to run power from the house battery to the bilge switch directly, rather than through the battery combiner switch, some may see no need for a battery monitor or battery to battery charger (especially if just using common flooded lead acid batteries rather than AGMs), etc.

BTW, read Calder's section on batteries to get a good understanding of which one would be suit your needs best. I'm going to be on some week-long trips, maybe longer, so the performance of the house battery is critical to my needs, while still wanting to keep things light. That led me to true deep-cycle AGM batteries for a variety of reasons, all of which Calder explains. If you're just going to run out, fish for the day or overnight, and come back in, the house battery and how it gets charged becomes less critical to the experience in some regards.

It's a bit of work, especially working up and within all the lockers. Felt like a pretzel several times!

I think your system is well laid out and looks very good ... :D

It's been awhile since I've looked at combiners .... I thought they charged both batteries and that one of their main functions was to manage charging so that only one battery charges at a time (generally the start battery gets all the current first if it's a lower-resistance battery compared to the house side, then as it becomes charged, charging switches to the house battery(ies)).... no?

Thanks Brian - you're thinking of an automatic charging relay (Blue Sea Systems calls theirs an ACR), often packaged together with a battery switch by Blue Seas and called "Add a battery kit". The problem is that this kit does not provide smart charging, it just provides whatever charging is native to the outboard's simplistic voltage regulator, which if far from optimal for AGM batteries.

So the switch you see in the photos above is just that - a manual switch, which will be normally "on", in which only the start battery interfaces with the engine, and the house battery only interfaces with things I've associated with it. If needed, I can put it to "combine" to start the engine using the house battery. This is a Blue Seas Dual Circuit Plus switch. Critically, it has "make before break" connections, allowing you to flip the switch while the engine is running without any arcing or damage. Another instance where I had to spend many hours just to figure out which combiner switch to get and exactly why! It gets fatiguing.....

Ah ... I see what you're saying now.  I was indeed thinking of the ACR, and I didn't realize the conflict with smart charging that the AGMs need.  You're probably about ready to write your own book on wiring boats now, right?  LOL....
