I prefer the maleron seacocks for my particular boat. For me it's several less underwater metal fittings to worry about bonding and corrosion
. The only downside I can think of is in the event of snapping off the thru hull
flange in a collision
. This could be taken care of by using a flush mounted thru hull
if possible. The handle does seem to be the weak point on these though I have yet to break one. With a trimaran
, weight is always an issue and what I save with the plastic seacocks lets me carry another case of beer
. I am perfectly comfortable with plastic, if one does fail/break it is a major hassle and mess but not a boat or life threatening issue. If they were located in an engine
compartment I would stick with bronze.
