I used to stop at villa marina everytime I was in Fajardo just to look at that beauty. I havn't seen it in months and thought it went back to florida some time ago.
I've done the run from the southern US to Puerto Rico in a relatively small boat (47 foot). I didn't want to mess with extra tanks or fuel blatters so we stopped along the way. From New Orleans to San Juan the longest open run was from Provo to Puerto Plata at 163 NM.
Doc is right though, 93 would be hard to get, no problem with diesel or reg gas but you'll pay. I ran into some other guys a few years ago who made a run from Miami in a 26 Grady White Cat with four strokes. No problem and the outer Bahamas and Turks and Cacios are lots of fun, if you don't have to worry about a calender you could just keep going its only 110 NM from Roadtown to St. Marten and if you get that far why stop.
