What is this strange bilge object?

I would post a picture but I can't seem to make it work. (97 kb!!!! max file size... Are you kidding???) Can someone help me post some photos?

The object is fiberglassed to the bottom of the hull. It is a red threaded cap with a wire pull tab in the center. I can't unscrew it and I can't pull the center cap free either. An inspection of the outer hull does not show ANY evidence of a thru hull. I have NO idea what it may be. BTW there are no wires or electrical components to speak of so I do not believe it is a transducer. There is also a similar one in the other hull (catamaran)???

Obviously a picture is worth a thousand words but unless I can find a way of compressing a 4 MB file down below 97kb and not have it look like a pixelated mess...I'm out of luck.

Do NOT pull on that tab - it is the detonator and if you succeed in getting it free your engine will explode !!!!!

maybe that's how they lifted the hull out of the mold

What kind of cat is this and how big

1955 Blanchard 51 Custom ( I got a woody )

1974 Ranger 33

what kind of boat is it? is it cored?

they are most certainly not in the original glass lay up. i wonder if they a point for pumping in an expanding foam. ie you take 2 hull molds one as the inner and one as the out then pump in a 2 part expanding foam to "core" the hull. or it maybe a vacuum port for when they put the outer and inner in with a core coated in resin then sucked em together

It would really help if you said what make/model boat you had.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

Looks like its a plug that fills the hole where the speedo transducer ( little paddlewheel thingee) went. Have something just like that but the cap isn't red. Unless you sail all the time, the speedo transducer gets fouled and you have to pull it and clean it to get a reading. Before GPS I got really quick at pulling the transducer and replacing it with the plug and vice versa. Idea was not to sink my boat. Now I get my speed from the GPS and have put the plug in permanently and glassed over the hole in the bottom.
