I'm curious the cost to have that custom made ?
The 1st one pictured is around $600 and I'm guessing for about the same or not much more you can have one custom made to your liking.
I don't think these off the shelf mounts look right on a downeast boat.
I have seen a product called Marine Penetrol used as a polish for sailboat masts. It will last a season and is simple to apply.Im going to leave i like that. I used an acid for cleaning aluminum trailers to get it to shine like that.
