Epoxy barrier and bottom paint
« on: May 21, 2019, 07:52:33 PM »
Does anyone have any input on epoxy barrier coating?

I purchased #98 and a planning on mooring it in lake Ontario.  Unfortunately trailer sailing/dry sailing is not an option for me.

The yard where it is awaiting having work done is a bit concerned that sufficient epoxy coating (3 coats) will interfere with raising/lowering the keel.   Is there any merit to this concern?

Also, regarding bottom paint does anyone have any input?  I was considering vc17, but am getting directed towards Micron CSC.  Any thoughts?

Since no one has responded I guess I will.

I don't know if the U20 needs an epoxy barrier coat because to my understanding you only need one if the resin used below the waterline is polyester. Since the boat was built fairly recent I would say it has a good chance of being vinylester and the epoxy coat is not needed. On the other hand the boat is intended to be dry sailed so maybe the designers decided polyester would be adequate.

In my opinion the money spent applying the barrier coat, then applying bottom paint, then cleaning the bottom regularly, then re-applying bottom paint would be better spent on a lift. It doesn't take much of a lift to get the U20 out of the water. Maybe a couple 1000# pile-mounted hand-crank davits, or maybe a floating lift that plugs into shore power - dunno but I'm interested in an economical lift system myself.

 Watching boats get listed and sold, I can say that painting it will effect interest when you ever sell it.
