Tigresse, which can carry 60 passengers, is, according to its owner, the largest sailing catamaran in African waters, rivalled only by the Fujicat, a sister catamaran.
At R110 for a one-and-a-half-hour cruise, it's not at all expensive (in my opinion). If I were you however, I'd consider doing the sunset cruise with champagne for R180. Their website notes that they offer a champagne cruise, and even though I know they really mean sparkling wine, please insist on REAL champagne from Champagne... just to make the point! ;)
We're currently on vacation so credit for today's photo of Tigresse goes to Mandy from brainwavez.org.
