Notes

A number of changes were made during the production run of the SOUTH COAST 21. The keel was moved a few inches back in boats with hull numbers greater than 90 to reduce weather helm. When it was found that this did not completely solve the problem, the rudder was made larger.
The boat was available fully finished or in kit form.
