Author Topic:   Lag Bolts below waterline

Matt F posted 08-01-2008 09:40 AM ET (US)
Admittedly, my question is not about a Whaler, but rather its Edgewater cousin.
That said, I’m thinking of buying a used one and the hull looks to be in decent condition. However, the one area of concern I have is where a swim platform was attached to the hull by way of lag bolts below the water line.
One of these has loosened over the years and has allowed some degree of water to pass into the hull – when I further loosened the bolt there was a very slight trickle.
The mechanic who was helping me survey the boat (yes – a mechanic, not a proper surveyor) seemed to not think it an issue, just that it needed a new and larger lag bolt and some 5200.
Does anyone think this an issue? I did not see any evidence of delamination. Any advice would be greatly appreciated.

are edgewaters constructed like a whaler

Edgewaters are the second to last boat company founded by Bob Dougherty and son Steve. They now have Everglades. The small, tight knit boat building town of Edgewater, FL. No, the Edgewater is not built like a Whaler. It does not have foam filled cavities everywhere. However, it is all composite, no wood. That's good. Unlike closed cell foam that when drilled into, i.e., mounting a swim platform, they will not absorb water because of their engineered properties. Divinylcell, Nidacore, Coosa, these composites won't absorb water if the outer skin is broken. BASF 2-part closed cell foam will. This is what Whaler uses, and although it truly makes for an unsinkable boat due to the fact that, even if you cut the boat in half, it can only absorb a finite quantity of water, and Whaler engineers designed their boats so that there was more bouyancy than was necessary, it will add a lot of weight.
Allow your mounting holes to dry for a bit, shoot some 5200 in there, and remount, as long as the holes aren't oversized. If they are wallowed out, select a new location about 3/4" below or above the existing location, remount, patch the old holes, and you're good to go.

if its not built like a whaler and you think the hull might hold water ,,just how thick is the hull and what is its construction materials

SeaBob--Thanks so much for the advice.
I had an old 13 foot whaler growing up (probably of a 1960s vintage) and water got into the hull -- it must have weighed a ton. Very much hoping to avoid a repeat of that.

Matt,
You won't have a repeat of that, but make sure all the weep holes in the stringers are not obstructed, so that any water that gets down into the bilge areas has a chance to drain aft where the pump can take care of it.
