[Rhodes22-list] Bob Weber's Analysis Of Lee Helm

[Roger Pihlaja]

Bob,

Given the way the hull & shoal draft keel are molded together in one piece, it's hard to understand how the shoal draft keel could be misaligned or misshaped.  However, your suggested diagnostic test involving pushing the boat & noting a definite tendancy to veer one direction or the other during the glide seems quite definitive.  Plus, it has the advantage of being simple & quick.  If there is something crooked down there, your push/glide test will point it out.  If your push/glide test shows no definite tendency to favor one direction over the other; then, all the hypothesis regarding hull & keel shape &/or misalignment can be put to rest.  I wonder if the GBI factory has something akin to a "Go/No Go" gauge for shoal draft keel shape & alignment?
