Welcome Steve to CSC
Good Luck with your refurbishing. I agree with Warthog that a bracket would not suit a 20' unless it was a flotation type.
BTW: I would also think twice about making a Bahamas trip in a 20'. I have made several and those seas can get pretty nasty in the Gulfstream coming off the Bahama Bank. Those summer thunder boomers can also spring up quickly and kick your azz
Make sure you consider the extra gear,supplies,coolers,people etc. that is required to make a crossing. I don't know what your fuel capacity will be nor your 200hp fuel burn estimate in a head sea but West End is approx 58nm from West Palm Beach. The closest trip would be to Bimini. If you left out of Miami Harbor it would be approx 42nm.
