Best Keel for Coastal and Blue Water Cruising
A quick comment on Marelon throughulls. I have a 15 year old boat that lives in the water and gets sailed year round. It now has all Marelon through hulls and seacocks. When I bought the boat it had one bronze seacock. I still have all of the Marelon Seacocks and they all work and they have not required any maintenance. The bronze seacock, dispite a lot of maintenance (twice a year lubing, and once every other year disassembly and relapping) leaked on and oof for the whole time it was in the boat and so I replaced it with a Marelon through-hull and seacock.
I am not sure what I would do about through hulls if I was going offshore, but I know that I would not replace a Marelon through-hull and seacock just because it was Marelon.
