Through Hull Fittings - Straight Answers Needed

[barnakiel]

Not many Marelon or other reinforced plastics fittings here in EU. Maybe alloy boats have them. Or maybe the regulation says something about 'the metal used'?

I bet the Marelon is sort of North American thing.

The other thing with Marelon, is that from lack of use the ball sticks and handle breaks off.!!

Yeah, it's real tough stuff, but the handle isnt and the problem is an issue. They are real hard to turn to start with. Some people say they are OK if you cycle them monthly, but I'm not convinced. Too bad, like I say the housing cant be broken with a hammer. Go to a West marine, pick up a 1.5 in Marelon valve and try to turn it!

I've never seen a chrome bronze seacock. Have seen chrome bronze thru hull fittings though. I'd be real surprised if an aluminum yacht builder put bronze seacocks in. Those might be shiny Stainless ones. Bronze turns aluminum to powder real fast....

Just went to a lecture at the Cruising Association on the brass seacock situation. I am scratching my head... definitely in the amazingbuttrue category.

Wrote a summary of my lecture notes here: The Cruising Kitty: The Wrong Seacocks Can Sink Your Boat

Does the same situation exist in the US?
