The deck

Building out the deck for this boat is about as straightforward as it gets in terms of the big bones.  It'll take some time after the first big step to get everything positioned and ready to cover up.
Some details.  First, I'm cheating on the deck - it's 6mm Baltic Birch underlayment.  I know - red flags going up all over the place.  But - I've talked to several local builders, and they've built their entire boats from the stuff.  Waterproof glue, no voids, 5 layer, and it will all be flow coated with epoxy before it gets sealed up in any case.  I'm still using marine Okuome plywood for the hull, but at a 4:1 difference in price, I'll experiement with the deck.
Construction:
The side rails are 3 layers of 6mm laminated with epoxy (and a little cabosil).  It adds a little weight, but it won't warp or twist, and it's idiot strong.
Cross-beams - 6mm ply, with 1.5x3.5" boards laminated between 1-2 and 12-13.  Spacing worked out to be 11" between frames.
6mm spacers will be laminated to the rails to lock the cross-beams in place,
Once these are in place, the slots on the ground will be carry 4" to 9" wide 6mm doubler plates running the length of the deck.  These will help distribute the load, ensuring we don't develop soft spots from walking, etc. 
Sample deck plates fitted into the cross beam slots.
We will also add additional doublers (triplers?) for the motor mount area, and laterally between frames to carry the battery on it's slid to the side rail.  And additional blocking for things like the stern rails, deck furniture and cleats.
The entire thing will be bolted to the hull with 1/2" stainless bolts, running in Delrin sleeves, and mounted fore and aft on each side. 






Today was also the final fitting for all the frames on one hull.  All the stringers have been notched, and final fitting of the bow will happen tomorrow.  At that point, we can begin the somewhat tedious job of gluing, followed by planing stringers onto the lines, and thn finally it'll be time to skin!

It's starting to look like a boat!

Launching the Skoota 16

Glassed, assembled, and we recruited about 6 folks from the shop to get it down the loading dock and onto the trailer.  The bench and battery box are mounted on T-track that's screwed to the deck.  You can see the microballoon 'schmeer' on the hulls, but it fairs up so quickly when sanding.  The deck cleats are positioned as far forward from the access cover as I could stick my arm in to reach the backing nuts.  You can see the tumblehome on the bow and shear line here.  I'm really glad we took the time and effort to add this detail. The console is okume with walnut trim.  View from the rear.  It looks slightly distorted perspective.  The motor mount is a stock Garelick, modified to lower it a couple of inches.  The rails are off the old launch  I'm really terrible about getting pictures made.  I haven't made the leap to the full instagram generation, but here it is on the water, first day 18, Sept 2019 It floated on its lines, and has ab

Assembling the bits

Image
It's been entirely too long since the last post, and much has happened along the way.  The boat is basically finished and put away for the winter.  For those not from the upper midwest, the lake is now 6 or 8" thick and will remain so until March (or April). So for now, I'll try to do some catch-up, trying to remember as many of the horror stories as possible! The last set of photos had the deck sitting in between the hulls, but nothing attached.  A couple of days later, we got back from regatta and started final assembly. After a lot of head scratching, I went of a fairly brute force approach to mating the deck and hull.  The photo on the right shows a 5/8" stainless bolt and 1" aluminum bar, tapped and designed to mount 'blind'.  In hindsight, I underestimated the difficulty of getting the darn things lined up and threads started.  This will get modified in the spring to have access hatches in the deck, and at whatever point the billets strip out,

Elves...

Not sure who else could've done it.  I got to the shop this evening, and found the strongback gone, and the hull sitting in a new cradle.  Must've been elves.  Port hull off the strongback I couldn't resist temptation and pulled the hull out of the workspace into the main shop, pulled the starboard hull out of its hidey hole, got some help with the deck, and viola!  It's a boat!  And everything fits (or close).   I've been trying to visualize the actual size - it's a lot bigger than I thought, and I'm quite pleased.  A lot of work yet to be done, but I'm pretty chuffed with where it's at today! Thanks, elves!!!
