On the docking note:
The best angle in which to approach a dock (obviously) varies... it's not so simple as "come in at 90 degrees." If, for example, you're heading north and there is a north east breeze, it's best to actually drive PAST the dock you want to pull in at, then turn the boat and idle in. Doing so, simply put, keeps you and your passengers from getting soaked. Wind direction, cuts in the reef, following seas, etc all determine the best angle of approach.
The ONE thing which is ALWAYS a constant, however, is that a captain should approach a dock SLOWLY and off plane. Perhaps the SINGLE GREATEST and most oft displayed act of stupidity ROUTINELY witnessed on the part of boat captains on this island, is driving too fast into a dock and relying upon abruptly shifting into 'reverse' to slow the boat down. I cannot possibly count the number of times water taxis have slammed into our dock. A number of times I've witnessed boats coming into dock fast where the engine stalled out when the captain went to shift into reverse and the boat hit the dock at speed (we had one boat rip a hole in its hull when it got caught up on one of our dock cleats when this exact thing happened.)
...I must confess though, there is a certain satisfaction in seeing some dumb ass captain, who thinks he's successfully docked driving like a hot shot, have his boat seconds later smashed into a dock by his own wake.
Few truly bad things can happen when you approach a dock slowly. Don't be an idiot.
