Drain Plug Location

[FishNCoach]

Hi all,

I have a new (to me) 1978 16 foot Hydo-Swift tri-hull.

I noticed that it's drain plug is located slightly ABOVE the level of the fiberglass floor.

My question is that shouldn't there be a drain plug BELOW the level of the floor? I would assume that there is framework and air space between the fiberglass floor and the bottom of the boat where water could get trapped and build up and become a problem.

I'm a little stumped about this. Is there normally a drain plug below floor level? Should I consider drilling a hole and installing one?

Any info would be appreciated.

Thanks much.

I would trust that the manufacturer knew where to locate the drain plug. I sure wouldn't be drilling any new holes to install another one.

A lot of boats from that era are built with a "sealed deck". The 3/4 ply is glued in place, 2-3 3" holes drilled in the center from front to back. Structural floatation foam poured in each hole then glassed over and tied into the rest of the hull. The problem is if there is a pin hole or screw that's not sealed, water WILL get in and water log the foam adding a couple hundred extra pounds a rotting the deck and transom from the inside out. I know from experience.
