Implications of changing the floor height

So, I've replaced the crack I cut in the hull with my reciprocating saw. I have the stringers glued in with PL and am in the process of cutting them to height. I would like to pitch the height of the floor slightly so that any water flows to the center and then the back of the boat. My measurements from the old floor lines however, leads me to believe that the floor pitched toward the outside of the boat near the front.

I've saved the bulkheads and the seat benches and would like to replace them in order to save me replicating them.

Is there any problems with raising the height of the floor an inch or so near the front of the boat?

Hope this all makes sense.

no......but the bow is naturally high.....so that is overkill.

i left my stringers high on the out side and lower in the center with drains in the center (well.....actually ....everywhere)

Yah, that makes sense how you did it oops....if what I'm seeing is right, the original manufacturer did ok in the back, but the stringers were high in the front and sloped to the outside instead of the inside, like I would have though. i just read your "cutting stringers to height" post....how did you determine there height?

Thanks

Re: Implications of changing the floor height

cause i measured before i ripped them out.....

but one inch in the bow wont hurt a bit......all it will do is raise your center of gravity. this is only a factor when the boat is tipped to the end of its righting arm.
generally the lower the better......but again......one inch wont hurt

I did measure before I ripped it out, but I guess only in the back and the middle front of the stringer. But, if what I'm seeing is what I think I'm seeing, the stringer is lower in the front of the boat, meaning the bow would slope toward the front. in my mind at least, this is exactly opposite of what you would want.

Does that make sense?

Ayuh,... When the boat is in the water, rather than on the wagon,..
It naturally pitches aft...

Re: Implications of changing the floor height

actually it does......the boat is heaver in the back.

so when the boat is on the boat is on the water the deck will be level. or close to.

just about all stringers are higher in the back than the front.....mine were 10 ins in the back and down to 6 amid ships..

what you can do is add another piece of wood.....like a second stringer outboard of the main stringers......so instead of 2 you run 4.....dont worry about protecting these ones as much as the main stringers......they will see very little if any water over 40 years.....make these slightly higher than your main stringers....this will give you a slight "v" in your deck. when you screw it down....the ply will naturally bow to the center.
