Flying Tako
From SecondSailing
Certainly the most common boat currently (1/08) in Second Life is the Tako 3.3, designed by Kanker Greenacre. You can buy a Tako at several locations in SL, a list of places is here. You can also rent Takos for free at many places. So if you just want to peek into sailing and you are not sure if you will like it.....rent a boat.
