I recently bought an 8 foot Sandpiper hard dinghy, thinking it might work 
better on the davits on Imzadi than the Zodiac inflatable I use now. I need 
some advice on how to make a reapir that is needed.
 
The Sandpiper is a molded ABS dinghy like a Walker Bay, with foam filling 
between the inner and outer skins. The center thwart of the boat is wood, and 
it appears that it was originally fixed in place with 4 screws that went into 
plastic plugs pushed into a ledge in the  inner skin of ABS. Apparently one or 
more of the plastic plugs got pulled out, and the PO secured the thwart with 
toggle bolts he bought at the Ace Hardware. With age, exposure, and use the 
toggle bolts have either corroded to extinction or pulled out of the ABS skin.
 
I’m thinking that I might be able to use a 1” hole saw to open up a hole in the 
inner skin, remove some of the foam core with a bent nail (like removing the 
balsa core in a deck) and fill the void with thickened epoxy. Then I would 
drill and tap the epoxy plug for the screws, and use LifeSeal between the 
thwart and the  ledge because LifeSeal is supposed to bond to ABS.
 
My concern is that the epoxy will damage the foam core, and will not bond to 
the ABS skin.
 
Has anyone had experience that can tell me whether this might or will not work? 
Or can anyone suggest an alternate way of attaching the thwart to the skin?
