I was down at National liquidators twice this week checking out 30+ foot boats, and was amazed at the number of MY's that had cheap arse plastic (Perko?) thru-hull fittings on them.

I have to think these were $100K+ boats when brand new, why cheap out on $100 worth of decent metal thru-hulls?

And why would a New Owner accept them that way from the Dealer? I mean you snap one of these off and your sunk...

:confused:

Simple.. the bottom line $$$ and the part will most likely get the manufacturer thru the warranty period with out problems. Sad but true.

So people could afford to buy them. If the boats are at national liquidators obviously people couldn't afford to even with plastic through hulls.

They last long enough for the repo-man to find the boat on the surface.

Pretty sure they meet some sort of federal standard though...

Were these through hulls above the waterline?
Were they Marelon or nylon/plastic?

Maybe it's not as simple as bottom line dollars. My Tiara has bronze below the waterline and Marelon above the waterline. I assure you Tiara does not cut corners - they use high-end materials and products, and gladly pass all of that cost along to the owner.

Here's my (totally unsupported) theory - just a WAG
Through hulls above the waterline are more vulnerable to catching on docks and pillings. If you catch a bronze one and twist it in the hull, it can badly damage the hull and still cause a bad leak. A Marelon fitting is not cheap, is very strong, but will fail before the hull 'glass is badly damaged. Above the waterline, this would be preferable.

I almost changed my above waterline through hulls to metal and them came to the same conclusion Mike did when I snapped on on the dock. Easy enough to replace, though I would prefer having flush mounted ones.

Very good point and I didnt think of it that way. I am not knocking holes in what you are saying but doesn't SeaRay put metal ones on their boats.. above and below water ? Same company, just a higher priced unit off the line. I am sure there is more to it than that but ???

I agree with Mike - Mainship does the same thing - metal at or below waterline, plastic on hull side.

I'm not sure. What I remember is when we were shopping for our current boat we looked at a number of Sea Rays from 41' to 46'. All were expresses. I can't be certain, but I don't recall seeing bronze above the waterline. I do know for sure that the one 460 Sundancer that I was seriously interested in had a mix of bronze and Marelon fittings. And when they came out of the factory, the SR's price points were well below the Tiara's.

The plastic fittings were above the water line (how else would I see them LOL :kidding) and I would say mid-hull....

Mike's response does make some sort of sense, but it just looks really cheesy!

And for what it's worth, the Employee that I was talking to down there said jokingly that they were the 'Largest SeaRay Dealership in the world'!

I thought that was pretty funny...

:D

Another not so small point is that plastic does not corrode. Many a bronze fitting or even stainless has made a stain of a FG hull.

This is especially important when people do stuff like swabbing their hulls down with acid like on/off which can bugger up a metal fitting nicely.

A pro kayaker friend installed stainless fittings on his new kevlar dream boat (nothing is too good for this boat) within a week one fitting was bashed into and pulled out of the jellcoat. After the repair the origional plastic fittings were reinstalled.

They don't corrode per se, but plastic will start to crumble and get brittle from exposure to UV rays. Marelon won't. So just because it looks like plastic doesn't mean it is.

My Trophy has bronze fittings below the water line and marelon above. I did purchase replacement chromed bronze fittings for the above water line fittings but life through me a curve before I could put them in. It could be a project for this year or next.

cheap arse plastic (Perko?) thru-hull fittings

Can you visually tell the difference between plastic, nylon, Marelon, and FRP? Do you know what the durability differences are? It may not really be what you think it looks like.

Given the choice of Marelon or metal, I'd go with Marelon every time. May not be as pretty, but it will likely outlive the metal, and be easier to remove if needed.

Nope, and Nope...

And if they are so great, why don't the really big boats 70'+ have them?

:o

It just struck me as odd while looking at all the different boats, and thought I would ask the question.

Some have them, some don't...

SOme research turned up that the big boats DO use Marelon. Some of the reasons include its total corrosion resistance, its light weight, and that Marelon valves are maintenance free (except for some lubrication) . The fact that it's not a conductor aids in overall corrosion control too.

Forespar reports that,
"Marelon® plumbing is now used by custom builders such as Wally Yachts, Oyster, Swan, Baltic, Morris and many other production builders such as Wellcraft, Boston Whaler, Sabre, Godfrey, Triton, Hinkley, S-2/Tiara, Baja, Cobalt, and more than 100 others, power and sail. Virtually all North American production boat builders use some Marelon® plumbing components in their boats. Forespar® ships over 45,000 valves a year to service these builders and have been supplying quality-plumbing components made of engineering polymers since 1982."

Interestingly, Sea Ray was one of the first to adopt Marelon.
