Pearson 27 keel
John,The wing keel on the 27 is a bolt on and is lead.The 27 was designed by Bill Shaw as a family of boats from the 27 thru the 39. I'm not sure which size was the "mother" design, but think it was the 39. The sizes in the new family that duplicated previous size numbers have been dubed the -2 series (i.e P36-2). The family was designed in 1984 /1985 and the first models were introduced as 1985 models.There are some very characteristic manufacturing features on Pearson hulls that were carried over from previous hull families that can identify the Bill Shaw designs, including the main support structure, shroud loading points, mast loading, skegs, engine location, etc.We have a 27 in the marina with my boat and the owner loves it. It looks like new after twenty years.Dave
