kidsdream:Guys - if the wind is blowing near 15knts the day before and it is looking to be the same for the day you are going dive, you should call Biscayne up in advance.
That operator will cancel trips when almost everybody else in Southern Florida is going out. On my first trip they scubbed our scheduled wall dive about 1/2 way out and we did some good shallow dives.
The second time I tried them they cancelled the dives after I drove up from KL.
It depends on who's driving the boat that day. They used to have three different captains when they offered daily trips (as a franchise of Divers Unlimited) although I'm not sure how many they have now.
I put 15 on their boat back in April and they ran in conditions that were borderline IMO but it kept everyone happy.
Also, we now have ten divers on this trip.
