Just repaired one of our Waves that had holes at the skegs. Filled with 5200, then formed 18 gage aluminum sheet over skeg, and secured with 3/16in rivets. We will see how it works. After several years of hard use, the skegs was wearing through. Also, had problems with 2004 models, weak transoms. Fixed by putting 3/4 in plywood brace inside hulls, and bolting with upper rudder pintle bolts, and additional bolts, with fender washers. After several years of service they are doing fine. Also added access ports on hulls. Another fix for shroud chain plates. Added backing plate, and thru bolts on chain plates. You can access thru ports under the forward hull pads. We have seven Waves at Sail Sand Point in Seattle, that get severe use.
