Thanks for all the info. I'm glad I ask the question. The tank I ordered is a std tank. Hopefully it passes the new inspection standards. I will loop the hose in a coil so that water flows out. I was planning on flashing in the tank. Should I make the deck above it removable?

Thanks
Cbuf.

How do you know when it is time to clean up your work area?
When you have about 40 clamps but you can only find 2 of them
When you have 12 pencils and 12 fine point pens and cant find any
When you constantly trip over all the cut offs

Well I hit that point. I had to glue on a bunch of broads and couldn't find the right size clamps! In tearing through the boat I knocked over what I was working on and caused a mess. No more work until I clean the boat. Hopefully I can get to it today.

I'm really under the gun. I need to get the back deck on so I can get the motor and float it before it gets any colder. We had 1/4 inch of frost this morning. I probably have a month and a half before ice up.

Flashing in the tank?

You can make a removeable panel and seal with 3M 4200 if you want.

This is not helping my cause. At this point I might need to find an indoor pool to float my boat in. I would have made more progress in the last 2 weeks but work travel and building a set for the little mermaid the musical at my daughters school has eaten up my time.

Hopefully I can put in 10 hours this weekend.

What do you build the inner part of the gunnel frame with? 1/4 strips, 3/8 strips, I assume I need to build up a thickness of 1 inch or so. Also how tall should it be? I'm thinking 1 1/2 inches then the 3/8 decking.

Thoughts

Thanks

The cleats are 1x1 nominal which is a 3/4" square batten but you can make them as thin a 3/8" by cutting strips from left over plywood.
Along the hull sheer, inside, I would use strips between the frames. There can be a gap, not need to bevel anything.
Those cleats are visible on the construction drawing, plan view. I do not show all of them for clarity but you can see the gap.
Along the inside edge of the side decks, the coaming edge, on the same drawing, you see a curved batten in one piece. It is clear in the perspective view. The curve is smooth and a 1x1 will bend but you can also use a plywood strip like a 3/8 strip 1" high. Make it in one piece to get a smooth curve.
You can make it from 2 layers of 1/4" if you want, it will bend.
I show a coaming plank glued to the inside face but some builders prefer a clean round corner: TBP. The coaming I show is a 1x3 plank (2.5" high).

Built the outside rubrail first, from 2 layers of 1/4", leftover strips.
All that is visible in the "Typical Frame" drawing but I do not give specs for the batten sections: you have a good amount of freedom there: minimum 3/8 thick.

Thanks for the info. Since the span is exactly 8 feet without the curve I plan to buy a 10' 1x5 piece of cedar. Then rip it down to 1/2 × 1.125" and have 2 per side. I figure 1/2 will bend better and having about an inch seems beefier considering I fish with guy that are bigger. I also plan on doubling up on gunnel support with 2 - 3/8 frames/rod holders.

Thanks
Cbuf.
