  1. I used to crew on a boat that had a conventional Edson type wheel with metal spokes, but with a wooden rim. It looked great and was easy on the hands in almost any weather.
  2. Sailed on LIS 35 years ago. I don't miss LIS summertime winds. We used to refer to the wind forecast as the "dead sea scrolls"
  3. Given that a decent set of foul weather gear costs more than any suit I ever owned back when I wore suits to an executive job, the definition of "good clothes" needs refinements.
  4. Mainly I was wondering about the practicalities of using a (mainstream, not-ruggedized) tablet in a ruggedized aftermarket case, in the environment with bright sunshine, salt spray, waves, gloves, etc.
  5. What experience does anyone here have with any of the major Android tablets plus an otterbox type case?
  6. What many seem to be missing is that the proposed systems measure performance, not the presence of alcohol or other drugs. So it doesn't matter if your driving is sloppy because you're drunk, because you're tired, because you're coming down with a bad flu, or because you just had a huge fight with your spouse; the objective is to see if you're up to the job of driving at the moment. This takes performance measurement out of the realm of legislating morality and punishing malfeasance, and into the realm of reality-based safety management.
  7. Note the fiddles on either side of the table? That seems like an excessive amount of mahogany for a boat of this type.
  8. For most of us mere mortals, time spent perfecting our boathandling beats time spent polishing the bottom.
  9. Hah... this is an endless conversation at yacht club bars, where everyone becomes a fluid dynamics expert. The only thing that matters is surface smoothness. And it matters a lot. On this the MIT scientists and the legendary Bethwaites agree: Sanding to 3000 grit and polishing to mirror finish is faster than 800 grit. It is as a practical matter impossible to make a hull smooth enough that laminar flow stays attached the entire length of the hull. It invariably breaks into turbulent flow a little bit back from the bow. The smoother the surface, the longer the laminar flow
  10. You'd need to be sure to fit this hatch with a high quality screen door, to keep out unwelcome sea critters.
  11. The "how much weight can it carry vs displacement?" argument is running into the theory vs practice divide. Obviously, one could in theory design an extremely light displacement boat that could carry an enormous amount of stuff. As a practical matter, very light displacement boats are, in general, designed around the objective of sailing fast when lightly loaded, with performance that tends to fall off pretty quickly as weight is added, and heavier displacement boats are, in general, designed around different objectives, that result in them being able to soldier on when heavily loaded.
  12. Boat X has a design total weight of 5,000. Boat Y has a design total weight of 10,000. Add 2,000 of gear and supplies. Boat X is 40% over its design weight. Boat Y is 20% over its design weight.
  13. My wild, not particularly well-informed guess is that the 0183 gateway is slowing down the message traffic on the N2K side, and AIS doesn't like that. Like, maybe, the AIS data source is waiting for acknowledgements from everyone before sending the next message, and the acknowledgements are slow coming back from the 0183 side? (Like I said, wild guess)
  14. Speaking as someone with a bit of mathematical background, I find that particular wording (which appears in a number of places) almost impossible to parse. The CSF formula is Bmax divided by the cube root of displacement volume, i.e., bmax / vol^1/3
  15. Dave Perry once said that a rules question that stumped him: Singlehanded dinghy sailor falls overboard right before leeward mark. Empty boat, rocking and rolling without weight of crew, somehow manages to execute a near perfect gybe around the mark without touching it. Crew climbs back on board and finishes race. Under the RRS, does boat and crew need to round the mark?
