I'm installing Andersen 40 ST winches port and starboard on the cabin top. The base on these winches is a higher profile than the Barients I removed. I'd like to raise the rope clutches about half an inch with some kind of base. I thought of using starboard but I'm concerned that starboard's inability to adhere with any caulk will make it likely to leak from the stresses usually applied to deck hardware. Any opinions on the use of starboard? I don't want to use teak or any other wood. Would appreciate any suggestions. Thanks!
