Re: 28 footer recommendations (Pearson 28-2 equivalents?)
Any 1986 Pearson 28 is a 28-2.
The 28 SL that you are looking at is probably a shoal draft. That has a shorter but broader keel that is also heavier. It won't go upwind as well as the fin keel, but works better in skinnier water.
boats that I sail on regularly: Pearson 28-2, Rondar 505, Yankee 30, Blanchard Junior
