  1. The thing about the first foiling cats in San Francisco was that there were random passing lanes: if anyone fell off foils, that instantly made a passing opportunity. That went away with the next two AC events. And with it, the excitement. Racing without excitement is not exciting. A multi-mode boat, that planes or not, with sail changes, tweaks, ability to tack and gybe lots of times with minimal speed impact: passing lanes.
  2. My boat is an Olson 40 set up only for cruising and explicitly not for racing. One thing I intentionally did was to make the boat safer: less likely to injure or kill crew. One way I made the boat safer was by the way the main is rigged. 1) The vang is a Vang Master (now branded by Harken). This is a tubular vang with an air filled cylinder to provide upward force on the boom, eliminating the need for a topping lift. I removed the tackle, so the vang can ONLY push the boom upward, it cannot keep the boom down. 2) I eliminated the traveller, and instead I use two separate ma
  3. It is weird to me that the above goals, pretty obvious, are not being emphasized. Instead, big expensive weird boats that don't require sailors. Like watching one guy playing a video game nobody else can buy. 1) Unique AC class 2) Best sailors. 3) Lots of passing lanes. AC75 is perhaps the worst possible boat if (2) or (3) matter at all.
  4. All this talk of not doing the AC defense in NZ. So idiotic. It’s just stupidly expensive, for no advantage whatsoever to the sport of sailing, spectators, or sponsors. Clearly true, or there would be zero problems. Good things to do: 1) An AC only class 2) The world’s best sailors 3) Close racing with many passing lanes. Item 2 means the boats must be a refinement of common competition boats, and highly tweakable on the course while racing. Item 3 demands boats with multiple speed modes. So items 2 and 3 disqualify winged foiling cats. Instead, plan
  5. And, as Razor already mentioned: any boot or spartite does NOTHING about all the water that comes down inside the mast. Every hole in your mast for wires, hydraulics, internal or J tangs, and especially most spreader roots allow lots of water inside the spar. On my boat, none comes through at the deck, but about 2 gallons per day of rain comes down the inside of the mast.
  6. That is the rumor, based on a misinterpretation of beam structure that claims a keel stepped mast is a "fixed end" of a beam. This error is in many texts. But a keel stepped mast does NOT act as a fixed end of a beam. A fixed end requires the beam to be held perfectly straight, as if it was in a concrete foundation. But a mast pivots at the deck, and at the step. This means a keel stepped mast is like a simply supported beam. So in fact, a keel stepped mast is weaker as it is a longer beam, and the length works against you by the square of the length so a small increase in length is a big decr
  7. At first I was thinking about 1.5 feet, enough to easily sit on and drag one’s feet while sailing. But trying the action of climbing aboard, or helping someone climb aboard (MOB event) made a longer scoop seem safer. As it was being built, we tried it, and much preferred the longer scoop.
  8. So how has this worked for you?
  9. Finco Fabrication (Steve Brown) sprayed the decks using Awlgrip, including spraying the Awlgrip proprietary non-skid additive for the grey areas of the deck. He did it about 4 years ago. It came out GREAT and continues to be GREAT today. It seems just the right amount of grip. Very happy with that deck paint job!!
  10. The helm feel is light air is clearly improved. I have not yet been in big seas.
  11. Thanks for that feedback, Steele. The under deck actuators seem to always have clutches that consume about 12W (1A) continuously. That seems a large percentage of the total autopilot draw. Other than the clutch, in most conditions my boat requires no movement of the tiller once weather helm is dialed in. I can use shock cord for extended periods of time. So in my case, where my boat has very good directional stability, I might see a majority of autopilot energy consumption being that clutch. 12W x 24 is a 288 watt hours per day. Our refrigeration consumes abut 600 watt hours per day. Not
  12. Monkey and Dumas, thanks for that feedback. Perhaps I could put the tiller pilot, that is easy to disconnect, under deck on the under deck tiller arm I have for an under deck drive. Maybe. I'll have to try some things... The backlog for new autopilots is three to six months.
