The problem with crossing the Florida Straights to the Bahamas, is that several small boats per year are lost and never heard from again.
Palm Beach / Lake Worth to West End in a small boat should only be done in weather window of 48 hours of 'benign' conditions and absolutely NO north component wind nor NO from the North or NE swell running.
1. because weather forecasts can easily change and NOAA isnt 'that good' in forecasting weather for the Gulf Stream in the Florida Straights!!!!!
2. you need extra time to get to Great Sale Cay (or Mangrove Cay) in case if the pass/entrance into Old Bahama Bay / West End is untenable, rarely is it untenable but it does happen sometimes.
Its about 60-70 miles to West End, the *average* is about 4 kts. northward flow of the stream ... so need about 20° of south added to your magnetic course to account for proper 'set' to your course. Ive seen as high as 6+kts. on the axis of the stream in the FL STraights when there are large weather disturbances in the Gulf of Mex. 'pushing' water between Cuba and FL.
Winds from ANY north component can set the Gulf Stream to 'very nasty'. You only go on E or SE through westerly ... and hope that it stays from that direction.
Beware of NE trade winds (DEC — FEB) as they have a tendency to pump large swells 'around the corner' of the northern Abacos and the swells WILL change direction off the NE Abacos and will then be running North towards South 'against' the stream flow.
To check any crossing, before fully committing, you leave a Florida inlet and scan the eastern horizon with binoculars ... and if you see what appears to be 'elephants marching in line along the horizon', you do a 180 and wait until the 'stream lays down' ... in a day or two .... and no matter what NOAA is saying!
The best weather source info is NOT NOAA forecasts ... listen to Caribbean Weather (Chris Parker) on 4.045 mHz (Upper Side Band) starting at ~7:00 AM local time.
www.caribwx.com/ ... no charge to 'listen'.
NOAA gets it WRONG too many times to be of any value for crossing the Gulf Stream.
The ONLY charts to use once in the Bahamas are "Explorer Charts" .... and/or a NEW Garmin chartplotter that is already loaded with updated "Explorer Charts".
Simplest and safest for a small boat is to wait for an approaching large HIGH pressure system from the west with 'light' winds, no N or NE swell running ... and simply motor across (adding 20°M or more to account for the 'set' for a boat that can maintain 6kts.
A simple VHF radio with a WELL TUNED antenna is all you really need to communicate. Its a plus to have a handheld as a backup ... and just about everyone uses VHF in the Bahamas instead of telephones.
DO NOT follow the GPS rhumbline between any FL inlet to West End.... you want to be heading 'more southerly' at the beginning of the leg in the less strong flow, more South-easterly (that extra 20°) in the middle of the stream .... and then make your 'corrections' nearer to West End. Remember that a 24ft. boat will 'max. out' at about 5kts ... and the Gulf stream can be up to 4 kts. or sometimes greater .... and you will be at least 20°M (or more) 'against' the Gulf Stream to arrive in the Abacos ... about 3kts or less 'over the bottom' especially early and midway in your crossing.
If you miss West End because of unusual stream velocity, head for "Memory Rock" then go direct across the Little Bahama Bank to Great Sale Cay (or if still benign conditions go to Mangrove Cay) .... about 24-36 hours West Palm to Great Sale.
If an EPIRB is too expensive, get a "SPOT" ... and set up your messages before you leave.

With your waterline length you will be unable to keep up with the typical sized boats going east.
Leave WELL before dawn, use Ch13/16 and do TALK to the Big Commercial Ships in the stream so they KNOW exactly where you are .... unfortunately many dont speak English and will not answer; but try anyway. Many ships going to the Mediterranean will come close to the western Abaco shore ... so watch for ships ALL THE WAY ACROSS. IF they dont answer you, stay away far from them ... as probably no one is on the bridge, etc.!!!
If your not well experienced in open ocean sailing .... get your ocean experience long BEFORE you attempt to cross the Gulf Stream in the Florida Straights .... as if you miss the Abacos, ..... the next stop is Bermuda ..... or Ireland.
