OK, lets try for some real info this time and no insults. Do so-
called offshore boats really have good scuppers? Can anybody provide
a link to a pic of such?
Next, areas below the deck, are they sealed on offshore boats or
accessible via a hatch? How much do said hatches leak? (my sealed
compartments have 6" screw in type access ports).

I like Pasco. Interesting that he says to seal up scuppers if they
are too low and rely on bilge pumps.

In the pic he gave, the scupper was even with the cockpit sole, so why
have a bilge pump? Where is the pump pumping if the deck is supposed
to be sealed?

I looked over the Tolman last night, adding a deck would be no
problem. Even big scuppers would not be too difficult. I sure hate
losing access to my hull though.

In my opinion, bilge pumps are not for getting rid of water from a
greenie. They are for getting rid of water due to rain, condensation,
dripping shaft seals, etc.

Scuppers are for getting rid of greenie water ... in a hurry.

On some poorly constructed (or damaged) fiberglass boats, the joint
between the hull and the side decks is not done well, and water can get
in. If the hull is the typical cheap two-piecer with liner, that water
likely will run down between the outer hull and the liner, right into the
bilge.

I've also seen boats, though not in some time, where "grey water" drained
into the bilge.

I can think of at least a half dozen other reasons why water gets into the
bilge.



Mostly rain, I think, and the constant drip, drip, drip of the old style,
wax thread sealed stuffing box for the shafts and rudders. (Obviously not
talking about small, CC, outboards).

Also, deck hatches leak, windows leak, and, as you say, the hull/deck joint
often leaks.

When I remember, I pour a gallon of water and a bit of Simple Green
into the bilge of Yo Ho before I head out. The soup sloshes around for a
while. When I retrieve the boat, I open the transom drain and what the
bilge pump hasn't gotten rid of drips out.
