Evaluating the condition of the Hull framing - '87, 21' Sea Ray Seville CC

[Dr D]

Anyone know what is the most efficient way to access & evaluate the condition of all the wooden structural framing below the flooring, & throughout the entire hull of my boat ??.....(Ideally, without ripping the entire boat completely apart)
I found what appears to be some "dry rot" on the forward wall of the engine compartment. Are there cameras like a plumber might use (eg; to examine a blocked drainage pipe) that would allow me to clearly examine the spaces below deck ??

Thanks.......

I don't think a camera will work because Sea Ray fills the voids under the floor with an expandable foam. On a boat that size, the stringers and the transom are about the only true structural members to be concerned about, and you can see part or most of them from varous hatches ,etc in the floor. The other wooden members just support the floor in the boat. If you feel soft places when you move about, then you have something to be concerned about.

Thanks Frank,
I appreciate the input.

The only panel I've removed & strengthened, (with no rot noticed), is the floorboard over the gas tank. No soft spots anywhere else.
As for the spot in the engine compartment, the best access seems to be if I have the engine removed 1st before beginning repairs.
Thanks again.

The bulkheads on these earlier searays are prone to a little rot at that bulkhead as water will set in the corner when at rest.best thing to do i was told by marina is dry it with a radiant heater(check for gas fumes first) ,clean it with interlux 202 sand with 80 grit and clean again then epoxy it up.Of course the marina would probably do it for you for 500.00.A suveyor can also take water content readings along with soundings of the bottom to make sure the rest is in good condition.
