No but go out on the whale watching boats,its brill to see there babys lolling around.
I tried to hire a Honda 150 Rib but got knocked back as it was the owners of the day trip boats,and not for hire. Have a look at the Motor boating monthly at the charters section,there may be something there for Tenerife. You can always go diving real easy if you have your open water if not they will teach you for less than a £25 per trial dive to see if you like it.
Enjoy your holiday.
