The top speed of a sailboat is calulated by multiplying 1.34 by the square root of the vessel's waterline length. So, if you had a 100ft boat, the square root of that is 10 and it's top speed would be 13-14 knots. A production 30 foot crusing sailboat would get about 7 knots. There are about 7432 Nautical Miles between Galveston, TX and Cape Town, South Africa. So divide that distance by your speed and divide that by 24 to get the number of days it would take in a best case scenario (great weather, perfect route, 24-hour control). 100 Footer at 13 Knots = 23.8 Days 30 Footer at 7 Knots = 44.2 Days Good luck with that.
