Technically you are not meant to drink and drive in a speed boat, but a spot of lunch on a lovely beach and a swig or 10 of local beer or wine.......Mmmm, just don't go silly. If you hire from the San Stef people you can actually collect the boat from the watersports guy near the jetty in Arillas and drop it off there too. Dead simple. We had the Olga (10hp) from 10am-6pm and went to the very limits north and south for the full day and the fuel last year cost 40 euro (we used half a tank). I was surprised how nippy the 10hp boat was and its so so easy to operate, with the stick, it was wonderful to be in control of exactly where you wanted to go. The sheltered beaches, swimming and snorkling were great. There was two of us so with fuel it was 55 euros each, but even the Olga can take 4 people very nicely which would have taken it down to likely 30 euros s the extra weight would have used a bit more fuel. Well worth a try. GazCaz
