Bass Relief- A Seafari 25 rehab

[FishStretcher]

I haven't been in the bilges of enough 20-25 foot glass boats to speak to this, but that was my impression. Without really thinking about the boat as a whole structurally, just the parts I can easily see, and do math on, I purchased 1/2" and 3/4" divinycel H80. So the tank decks will be structural with 1/2" H80 and glass to support a poly tank or two. I will likely run a layer of 1708 up to the stringers to reinforce that tabbing. The under cockpit sole bulkheead will be doubled with 3/4" H80 sandwich core (and glass). I will leave the plywood in place, partly to hold hull shape while I put in the sandwich core bulkhead doubler but likely will remove the bottom 4-6" as it got wet once. Then I can remove the ply at my leisure. Then I hope to put a deck forward of there out of 1/2" sandwich core again to better support the area where the slamming loads are higher. Until I can fit another bulkhead under the vee berth.

The tank deck will be glassed/ tabbed to the hull on the top surface, and tacked to the keelson with 5200 adhesive. Or that's my plan.

Oh yeah, the bulkhead from the tanks to the engine bay need replacing, too.

I like sanding...
