What you want to end up with may depend some on the kind of sailing you expect to do. At sea, smaller cockpits are desirable because they hold less water if you get pooped. A smaller cockpit also puts contol
lines closer together so they can be handled more easily. In bad weather, a smaller dodger can be used, which causes less windage and may make the boat easier to maneuver. If you''re mostly daysailing, you and the crew will want to be on deck. Even so, a five foot cockpit should be plenty big enough for four people to sit around. Overnight, however, if four of you are planning to sleep aboard, you''re going to have to decide now whether you want four below (keep the cabin as it is) or if you want two below and two in the cockpit (lengthen the cockpit.)
