Ffs now iv got to think again lol.

Few questions then

Do the stringers need to be one piece and run front to back?

Could I fit bulk heads in and then just run stringers in between these?

Do the stringers sit on the Chines of the hull so there would be two a side?

All the old sparrowhawks and eagles just ran with foam inside and they all seem to hold up fine. If I do both bulkheads and stringers is this going to be overkill?

Will there be any adverse effect due to the hull being so stiff after?

Sorry for the questions just helps when I understand a little more.

I am not qualified to awnser this,

But if it was me two full length tied. Into transom with sandwiched knees ,, and a series bulkheads a max 750 ctrs would be my choice from 18mm Quality marine ply,,

Just to stop floor bouncing and to tye sides in,, But I am not a boat builder!!!

Biff was and is let him guide ya

Modern stuff is laminated foam shapes now
if concerned of weight being added but all that sodden foam would of been heavier for sure

The foam was actually dry that came out. It only came apart so I could repair the hull properly.

It basically what Nugent said. We cut a rough pattern go the stringers out of 18 mm ply and bond two together with grp Matt. I say roughly because you have to think about floor level. I'm thinking if you're asking such basic questions as these this project is going to be a near vertical learning curve for you

Tbh I didn't expect to have to go to this level when I got it. And after speaking to mike it didn't sound like an issue as was just bulk heads but stringers are not something I had thought about or even looked into

i would let an expert do it as Biff said or sort of said as that is a major job, I'm surprised they are like that.

Surely if the later model boats only use bulkheads then that's enough? I'd assume the later boats have been tested thoroughly & if that's the spec then I'd be happy to go with what the builder recommends
Osprey are a fairly respected builder who have been about a bit
I can't see the point in overdoing things if you don't need to,
If mike is happy to assist with ongoing advice then there's nothing like the satisfaction in doing the job yourself

Maybe later boats are built to a different schedule. I'd go with longitudinals every time, although some transverse structures as well aren't going to do any harm.
