Yes, you read it but without the technical understanding to properly
evaluate it.

The weight represented by the bilge keels would have had an insignificant
effect on stability. They were primarily devices to keep the boat upright
in British anchorages that dry out at low tide. Their removal would,
however, make the boat significantly less prone to the rollover by reducing
the low drag that trips the boat against the force of the wave crest on the
topsides. Possibly some loss of windward ability as well but this isn't
always the case if the boat also has a center keel. Getting bilge keels
exactly aligned with the flow is a black art and their drag can hurt
windward performance more than their extra area decreases leeway.

Bob Perry gave him excellent advice.

The fine points of naval architecture are one thing. The suggestion that
this was an insurance scam betrays a lack of common sense and the nature of
marine insurance rates that makes it hard for me to believe the person who
suggested it ever had occasion to buy insurance for a yacht.
