What's the floor made of?

Fiberglass.

I'd be surprised if the floors and hull do not have some sort of
non-fiberglass core - either wood or foam. You end up with a really
heavy boat right from the factory otherwise.


I've got a Scout 20.5 Sportsfish CC that is touted to be completely
fiberglass ... no wood in stringers.
Dry Weight w/o engine is 2,000 lbs.

That's cool. All you have to worry about is the foam being saturated
and I really have trouble believing that any foam could hold anything
even remotely appoaching the weight your think is an issue.

I think it's a combination of things - some soaked foam and residual
water being held in the bow somewhere.

I'm having the hull gone through with one of those fancy moisture
meters that reads through the hull.

We'll see.


Radioactive dye...that's the ticket.
Where would you be without my helpful ideas.

A hell of a lot closer to solving the problem.

No wood in stringers is different however from no wood anywhere.

Fiberglass stringers are usually built around a foam core just to give
them the required shape. A solid fiberglass floor is difficult to
make without either excessive weight or too much flexibility.

Unless it has more molded risers supporting the deck, which, as you point
out adds more weight.
BTW ... the Scout is 100% wood free. Some type of composite material is
used for the stringers and transom. They have a unique way of building
them.

I have seen that more and more builders are avoiding wood completely.
I've seen some stringers that are basically just strips of fiberglass.
Foam cores are just as bad as wood imho. It doesn't matter how good a
job is done covering the wood or foam because polyester resin is not
water proof. Water eventually will migrate through polyester resin.
Foam doesn't rot at least.

I'm still having trouble seeing 900lbs of water anywhere in a boat that
size. You'd have to be wading in it.

True. Also, on larger vessels, trim tanks are used to obtain optimum fore
and aft and side to side trim. In a former life a vessel of mine had trim
and ballast tanks. We used fresh water for ballast vs fuel. Safer and
cheaper, eh?

Many modern manufacturers use a foam core instead of plywood for the decks
but some, including Parker, still use plywood. Parker uses XL ply encased
in fiberglass. I saw some being built. The company is careful and
fastidious and makes sure no "bare wood" is exposed, even though XL
treated wood is resistant to rot. The wood, though, does add substantially
to the dry weight of the boat.

But weight, even on a planing boat, is not necessarily the devil's curse.
Most of the charter captains around here who drive the 46-footers want as
much weight as is practicable down low in the hull to help their boats
take on our nasty chop here in Chesapeake Bay. They'll sometimes spec much
more tankage than they really need, just to have the ability to add fuel
as "ballast" when conditions require.
