Should make landfall in St Martin, Great Bay on Thursday

From the look of the chart there are 2 marinas on the eastern side of the bay - At present I will aim to head to the more southerly of the two. If you could check their names and phone numbers / VHF channels for me that would be great. Otherwise all is fine. Position at 1600UT today is18d 12N56d 33W with wind E - ENE 16 to 27 with Occasional 33 knots, so we are a little slow as we are having to keep reefed as the wind is so up and down. Day run 138nm. We are hoping for Thursday - we are a little directionally challenged -but we should be able to pencil in Furuno for Friday - Does Furuno have an idea of a worst case scenario time scale? Oh probably not a bad idea for directions to a decent birthday cake -good thinking ; ) Regards Damian
