There have been issues w/ other boats losing the top plate of the keel foil. This plate keeps the keel from dropping out through the bottom of the boat.....in other words, a fairly important piece! One HUGE advantage to being a part of the second generation of boats is learning AHEAD of time what to avoid.
This is my plan:
Drill 3 x 1/4" holes down through the top of the foil
Cross drill 3 over sized holes where the first holes terminate
Flatten the top of the holes for plates and washers, bolt it all together and fill w/ epoxy and pray!
Here is the bulb atached (temporarily) to the bottom of the foil
So far so good!!!
