  1. We never cant the rig going downwind... only upwind or on a reach in light air. We have c-foils also, which do start to lift the bows above 15-17 knots boat speed. My feeling is that overall in the Pacific Northwest, the C-foils are not a net gain as we have mostly light winds. But that they make the boat a lot more forgiving and thus add a safety factor. We were in some terrible conditions (for a 650 lbs cat) in the 2017 R2AK race coming through Dixon entrance after a storm-- 25-30 knots wind on the quarter, 8-12 foot seas stacked up with an opposing tide. As the boat would start to surf
  2. I have a canting rig on my 26' racing catamaran- Felix. The canting mechanism is primarily setup to allow us to self right the boat if we get knocked over.... but we do use it from time to time for a performance boost if we are in more stable conditions. Canting the rig is a very noticeable gain for us when flying a hull.... mostly the increased righting moment of moving the mast past the center of gravity when sailing in waves. The mainsheet traveler has not been an issue for us-- but on our boat the helmsman has mainsheet in hand and is playing that to keep the hull skimming in those cond
  3. Hi Craigiri, Colin Angus' RowCruiser is a great boat-- I would love one for my quiver someday although I would put a pedal drive in it because I am not a rower. To be transparent here I have a pony in the race because my company cuts the kits for these and I have been involved in quite a few of the builds/ builder modifications. I'll try to be as unbiased as I can though with this. I would not recommend bright finish for the RowCruiser (or any wood boat that is stored outside on a trailer) as UV is a killer. You can put multiple layers of high end clear coat on it and protect it for a
  4. From my own building and repair experience the right Nomex for marine use is resin impreginated, has great compressive strength for its weight and does not let water migrate between cells. But in highly curved areas of the hull it is necisarry to go to overexpanded Nomex which is easier to fit. There are also Nomex choices which have slight scoring in the walls to propigate air release in layup and is more common in aerospace...but that choice would allow water migration. Also I have seen builders score the stuff to allow it to bend which would also aid water migration. Nomex can dr
  5. I did some work on her in Friday Harbor. Beautiful design that reeked of speed potential... epoxy kevlar laminate over strip foam construction. But on the heavy side of things with bog in some places over 3/8" thick. Would be great to see her fixed up and sailed to her potential.
  6. That's awesome! Need to change my avatar.
  7. That has always been one of my favorite big power cats--- amazing passage maker with plenty of bridgdeck clearance and beam. After owning a big multihull that we ran crewed charters on, I'm burned out on all the maintenance of a big complicated boat. I'm more interested in simpler and more manageable boats now... something you can put on a trailer in the winter and forget about till spring.
  8. There are a lot of powerboats that look the same at the Seattle Boat Show-- going on right now. The only power boat I really liked was the Surf Scoter 23 by Sam Devlin. It seemed to be the perfect combination of small enough to be easy to trailer, but big enough to spend the weekend on. Also it had the required inside pilot house and is efficient for its size and type. If I wasn't so into powercats for their efficiency and comfortable ride, I would be trying to figure out how to make one of these next.
  9. ProaSailor, That is a good reality check for an efficient power boat. I was at the Seattle Boat show yesterday looking to see what types of new boats where out there in this range. Boats that have equivalent rough water performance to Nige's powercat - ie deep V monohulls with enclosed cockpits, in the 22 - 24 foot range, that one would actually consider a comfortable boat to cross the Straight of Juan de Fuca -- those boats were in the $75K to $120K price range. Fuel consumption on those boats are from 1- 2.5 nmpg at 22 knots. Nige's boat is in the same price range and gets 5-7 nmpg.
  10. I see long and pointy bows as a huge asset in seakeeping of a powercat. If they are full/blunt and/or flared, they will create a lot more spray and cause the boat to pitch. If the design is setup right you slice through the waves with no fuss at all.
  11. Hi Nacrajon, Nige's powercat "Totoro" was inspired by a ride on Russell Brown's "Grasshopper"-- Tornado hulls with a 15 hp motor that can go 17 knots and cruise efficiently at 14 knots. I had been driving a couple small commercial powerboats that summer in the San Juans and Russell's boat really opened up my eyes to the potentials of displacement power cats. Hopefully he can post a picture of that cool boat. My guess would be that the Nacra would do really well if you could keep it light and keep the speed bellow 16 knots. The Seawind could be nicely efficient up to 12-14 knots or so.
  12. I am still wondering if there is a really good reason to have the main daggerboard in a boat with lifting foils in the amas.... I know Cheekee Monkey kept the main foil when they put in their lifting foils... does anyone have experience they would be willing to share sailing a trimaran fitted with lifting foils--- with the main hull daggerboard up or down? Can you only lose the main daggerboard by adequately controlling the direction of lift on the curved lifting foils?
  13. I am very interested in the F-85SR... hopefully someday I'll have the time and money to build one of these. I had a question about the necessity of the daggerboard in the main hull... when curved lifting foils are installed in the amas, could one do away with the daggerboard? I ask this because BMW/Oracle ended up removing their main daggerboard and rudder effectively. I assume they were able to do this because of their ability to cant their lifting foils to adjust direction of lift. The loads on those foils were incredible--- I seem to remember 120 tons-- and I imagine the mechanism
