Between a few Wind Horse<\/em> projects, playing with our progeny, and ogling the Florida seascape and fauna, work on the FPB 115 has had competition, but going on none-the-less. We have been chatting with professional crews, visiting with vendors, even the recent derating of our engines relates.<\/p>\n

It is relatively simple these days for us to predict smooth water power requirements. What is harder to calculate are rough water drags from wind and seas. We know from experience, based on fuel burn, with Wind Horse<\/em> the average<\/em> rough water drag increase is not more than 20%. But we don’t know the peak<\/em> requirements, and not wanting to be caught short the tendency is to have a high margin of safety. With the FPB 83 we think with the engines now at \u00a0M1, or 105 HP, still have sufficient grunt for adverse conditions. But only real world testing will tell us for certain.\u00a0Wind Horse<\/em> is essentially a half scale model of the FPB 115 (based on displacement) and so an excellent test vehicle. What we learn over the next few months about our derated performance will help dial in the FPB 115.<\/p>\n

One of the details to be considered at this stage of the design cycle is storage and handling of dinghies and other watercraft. Towards this end we visited with US Submarine in Vero Beach, Florida. Their two person 1000foot\/300m depth rated sub is the ideal vehicle for a quick tour around the bottom, if you can store, launch and retrieve it in less than perfect weather, and deal with the ancillary gear. Linda is shown above with a pallet of battery chargers, an oxygen generator, and assorted spares (blue tubs). We have some ideas for handling the three ton sub, and the gear will be easily absorbed.<\/p>\n

The roll over models have been refined and we are still playing with various combinations of ballast, loading, and buoyancy. Shown here (and in the first image) is a volumetric model for heeled stability studies. We are seeing results which are in line with or better than the early assumptions. We are happy with where the design stands in this regard. There remains a final pass through the interior and hull shape to go, and then we are ready to wrap up this phase.<\/p>\n

Now, before you start feeling sorry for the fact that we are working as we cruise a few photos follow from the local environs.<\/p>\n
