My lack of a water pump belt at West End in the Bahamas required I
spend an entire day getting said belt from Freeport. Most boats at
West End are bizaaro expensive and they would be willinbg to pay
nearly anything to get their parts quickly.
So...someone start a part delivery business from Freeport to any
isolated marina in Grand Bahama Island..
At West End there is no store for fishermen although fishing is THE
major industry there. Someone needs to start a store next to the
marina at West End selling stuff just for fishermen.

Getting rid of conch shells is a problem on GBI. So, bring thousands
of them to the USA and sell them for $1 each. Use a band saw to cut
off the spiral portion at the end and mount them onto flat coconut
husk pieces as coasters.
