Howard, you are welcome to drive west to see Osprey IIs bilge. She is at
Perry Lake, north of Lawrence.

Subject: Re: M_Boats: Bilge full of water
I keep reading about a "bilge" on the 17's, but Audasea doesn't have one.
Just a flat extension of the cabin sole back under the cockpit.
Would be interesting to see one with a bilge and to hear from Jerry if they
built them different back when.
One way to find out where the water gets in is to see where it seeps out.
Pull her out and pump the bilge full of water and wait to see where it drips
out.
My guess is is will be inside the bottom of the CB trunk, where the walls of
the trunk meet the edge of the CB slot.
I've never heard anyone say, but I think the way it's built is the entire
stub keel is layed up in the mold, and after the hull was popped from the
mold and the hull turned, the slot was cut, CB trunk installed, ballast
installed on both sides of the trunk and then sealed up....either on top of
the ballast, leaving a bilge, or well above the ballast, level with the
cabin sole, leaving a "dead space" between the top of the ballast and bottom
of the now sealed off sole.
Over time, the material and joint used to seal up the CB trunk walls and
keel stub goes south and the joint gives out, allowing water to seep into
the ballast cavity. With the steel or iron ballast, you can get rusting and
swelling. With lead, not much happens, except water collects. The fix would
be to clean out the crack, dry her out, fill the crack with thickened epoxy
and they put a layer of glass tape over
it. Sand all that smooth then put some bottom paint over it.
