1970 Seafari conversion to CC

The floor/stringer/hull combination on those boats forms a series of I beam boxes, very stiff. Bushwacker is the expert, but a 4 stringer 20 should not need bulkheads at all, as long as the floors are securely attached to the stringers and hull. Pretty sure my 20 Seafari had no bulkheads.

I need them to support the floor seams and dont mind the work. I saw somewhere that they could cause hard spots and possibly cause issues? I dont know I already have em cut and laminated just havent intalled em cause I heard about the hard spot thing.

You can put butt blocks on the unsupported joints; it's just a piece that spans underneath both sections of the sole.
Laminate to one section first and then glue with thickened epoxy when you attach the other section.
Between the stringers, side stringers, and the butt joints, you should be good.

My slacker 20 loves a full live well under her leaning post, but my 365# rude is on her transom.
I would agree with Denny on putting the live well in front of the console. At least plumb it that way and give yourself options. Not an ideal place to keep bait I know, but you can`t ignore balance.

Excellent thank u for the prompt feedback and I will keet yall posted.

This year I've needed the bow area for minimum 120lbs ice for all of the suicidal tuna we have been catching.

My boat will have a yeti 160 full of ice just in front of the console when im fishin so that will help a little too!

Connor's right, those 4 stringers are wide enough that they don't need a lot of transverse support from bulkheads to prevent buckling. Just tying them together with the floor should be enough. By bonding the entire 5/8+" thick inner liner to the top of the stringers, Moesly basically created a big I-Beam/box structure that was very stiff, both in bending and torsion. I would make sure the floor sections run completely across the hull from port to stbd to tie the stringers together, making sure they're well bonded to the top of the stringers. Transverse seams running across the stringers shouldn't cause any problems, but I would try to avoid making seams that run parallel to the stringers.

so its strong enough without em will it be stronger with them. I already cut em and am ready to install em. I would think they would be neccessary down the center cause its quite a span! Ive already done most of the work

the only parrallel seam is for the fuel tank hatch
