You will arrive at the catamaran in the afternoon and get settled in. We’ll then have an extensive briefing to explain about the basics of the boat and most importantly about safety on board. We may set sail that afternoon but it could only be the following morning and since we stop from Friday midday to Sunday morning for shabbat, it means that 7 days are never enough. Sailing is not fast and we need a couple of days after Shabbat to get back to our starting point.
For example, lets say you arrive on a Tuesday, we start sailing on Wednesday morning and then travel over 3 days to reach our furthest point where we stop for Shabbat.. we then we need 2 days to get back to our base by the following Tuesday.
