Listers-
My 30-1 has gate valves at the cockpit drain through-hulls. Don Casey
writes that gate valves are inherently unsafe and must not be
substituted for seacocks. Any opinions on this issue?
While I'm at it, Casey also writes that plastic (Marelon)
through-hulls should not be mixed with bronze nuts and seacocks, which
my boat does. He writes only plastic nuts and seacocks should be used
with plastic through-hulls. Thoughts on that one?
Thanks,
Randy Stafford
