Recently purchased a 1984 Seidelmann 30. Need to know if there is any difference between the 29-30 ft versions of this boat. The specs for IPJE seem identical.My new baby has a keel stepped mast, yanmar diesel, It's name is Kudzu and was sailed on the Chesapeak. Anyone know it? Also, does anyone know the PHRF rating. Does not have spinnaker gear but hope to add soon. Was about to sail from Solomons Island up the Chessie and Hudson and then to Lake Ontario via Erie Canal. But as of this writing, the canal is still closed so will truck to Wilson, NY.
