Welcome Trialsbikeadam, Happy New Year. You are starting 2019 right by joining us here at SBO. Everyone here is happy to help where they can. There is a lot of nautical knowledge, centuries worth, so stick around.
Most of us will agree, for a trip like Fort Lauderdale to Bimini, it's mostly about the sailor. Crossing the stream is normally an easy 10-12 hour small boat sail, but $#!t can happen so it's best to have good equipment and backup emergency plans. Choose your weather window conservatively.
I took a quick look at the Mac26 and have three positive comments about the trip. Check out this article

1. With a larger outboard, you can make much better time if the weather starts to look like it's taking a turn for the worst. That's a huge plus for the Mac26.
2. Macgregor claims she is self-righting with water tanks full. Excellent. Not a trip to take in a boat that can't recover from a knock down. Be sure to provision and arrange equipment so that is not defeated by bad storage choices.
3. Positive floatation. If all else goes wrong, AIS, EPIRB and water proof hands held radio will bring help quickly in those heavily traveled waters.
The negatives. She sounds like she's a little under built and may need a little breefing-up. I'd make sure to put backer plates on your rigging hardware. Nothing that can't be addressed without much trouble.
Good luck on your adventure. I'm looking forward to following your progress.
