We have been studying the motion of FPB64-3, Iron Lady, with an eye on what we are doing with the FPB 112. The difference uphill, between this and the previous 64s which do not have the swim step extension gives us some wonderful data. We shall shortly see how this works for ourselves, but for now we have to be content with video.
Thinking you might like to share we have posted five minutes here. This takes place in a tidal area so there are lots of steep waves in which to play. Throughout the video Iron Lady is running at 10/10.5 knots.
We are very pleased with what we are seeing, as is the owner who has done quite a few upwind miles on Wind Horse, so he has a benchmark with which to compare.
