The drive from the pier takes about 15 minutes, then the briefing about 15-20 minutes, then helmets and gloves and into the karts another 5-10 minutes, sailing about 45-50 minutes (you won't want longer, as your hands will get tired), then cold drink and a debrief another 15 minutes and 15 minutes back to the ship. So, the whole excursion takes 2 hours.
