None of our boats has any ballast added to them, and they are not self-righting (but they are much more stable than many assume). We prefer to keep the weight down and the performance up. These are small boats with low rigs. They are not intended for open ocean crossings (although we have had a Weekender in whistling winds and 12'-15' seas off Hanalei Bay). Proper attention to the mainsheet and gusts will keep you out of trouble most of the time. We haven't ever felt the need for ballast, but many people ask about it. We haven't tried it, so we can't comment too much. We can say this: several of the same people who were asking about adding ballast have written back (after building our boats without ballast) and have been convinced they made the right choice.
