Default Re: Boat porn of a 25 Seafari beasty

LCG is the Longitudinal Center of Gravity. We measure it in feet from the transom heel (bottom of transom at the keel)to the center of gravity. When represented as a %, it is the LCG measured length as described compared to the static wetted length of the boat. The Seacraft 25 has a wetted length of 22'at full load displacement. Thus, the 37% LCG at a heavy displacement I described equates to 7.9' from the transom heel. We chose this location for the trials because it is where the static trim of the boat is 0 and generally results in better seakeeping, especially in head seas. A more typical LCG for an average planing boat of this size is about 33% and very high speed boats will have a LCG of 30% or less.
