I'm a lead carpenter at Morris Yachts and would like to make sure we're clear on one of the points made in this article: although we do use the countersunk hole method when bedding all exterior fixtures, we have never used any type of butyl tape as permanent bedding for any pupose whatsoever, deck hardware or otherwise. All deck hardware on all Morris Yachts is bedded in 3M 4000 because it is UV resistant and removable if need be. Wooden brightwork items such as toerails, coaming caps, dorade boxes and wooden handrails are bedded in Sikaflex because it bonds better with wood than 4000.
I do realize that the article never states that we bed deck hardware with butyl tape at Morris; I just want to point this out to avoid any possible confusion.
This is why I was clear to not say that you guys used butyl. Just making the point of how critical the countersinking is and that most TOP QUALITY builders like Morris take the extra step to do it right.. Heck with proper countersinking Silly Putty might bed deck hardware....
Thank you for an excellent article and for giving credit to the true professional boatbuilding companies that care enough about their boats and appreciate their customers enough to always go the extra mile.
And you guys certainly do go the extra mile!! There are sooo many hidden "details" in a Morris that a customer will never see yet you guys still don't skimp or cut corners.
Have you guys tried Sika 295UV? It is a nice low adhesion PU sealant that is more easily removed than UV4000 and seems to yellow less for me than UV 4000? Would be interested in your thoughts.
Oh and butyl is also very UV resistant, the butyl on our 1979 CS-36 is 32 years old and still just as it was then, and it is actually more easily removable than UV 4000..
Of course it is more labor intensive in your environment than tube caulks..
Oh and I like the user name. Morris does rule...
P.S. Please don't refer to yourself as a "carpenter" you are a true craftsman and artist. I hire a carpenter to build a deck..
