San Juan 28 - Sailing Qualities?
My previous boat was a San Juan 28. I found it to be very well balanced and tracked very well upwind. I generally sailed her in 5-15 knots with a full main and 120% headsail. Above 15 knots, I needed to reef the mainsail to keep the helm balanced. I found that she heeled quick to about 15 degrees, but then settled in and felt very stable. Downwind she was a bit of a handful, as the pinched stern tended to yaw quite a bit with a following sea. Had a couple of fun knock downs because of that, but it was sporty out and I had up a large A-sail. Both times she recovered nicely. Overall, she was a great solid boat, and since she was my first keel boat, has a special place in my memory.
One maintenance note; check the chainplates for leaks. It's a weak point and caused at least one boat to lose her rig in the '80s sometime.
