    B&G H2000 update polar from FFD

    What are you really trying to accomplish? Adjust your target speeds in light air? Something else?

    Compass for H5000 - Thrane LT500?

    Sorry, no specifics but I did hear directly that the precision 9 compass had “issues” and was advised to steer a boat I was consulting with away from it.

    Compass for H5000 - Thrane LT500?

    Listen to your b&g guy, I have heard the same reservations from very high up in that group. Your general rule of thumb is to buy the best compass you can afford. Solid accurate heading info is key to a well calibrated system.

    eleictric outboard for a dinghy

    I never thought much about theft but have owned and used the Torqueedo for three years now. We added the larger battery last year to extend the range and kept the 5kw as a hot spare. Couldn't be happier with the performance, convenience and portability.

    Switching out speed transducers

    Not to belabor this but the nke sensor does require 12v to function so it sounds like it was wired correctly but it could still be set to output a 5v pulse. It may still be worth having that checked. As i’m sure you have found out, qualified nke dealers with the right programming tools are in short supply. You should contact nke’s importer. Euromarine Trading in Newport RI, they should be able to help. Good luck.

    Switching out speed transducers

    I’m assuming your boat was a used purchase and that you’re not sure how the nke ultrasonic was originally set up. Because B&G, for legacy purposes, used a 5v pulse (certainly through h3000) nke had a software setting to provide a 5V pluse for B&G systems. It was less than perfectly reliable in that setting. Although B&G would never officially tell you it was okay to use a 12v pulse the designer of the H2000 and H3000 processors verbally assured me that it would work fine at 12v. All that said you could send the unit back to nke and have them check how yours was programmed and ask for it to be set to 12v output. That might fix your issue. For 6 years I ran an nke ultrasonic on our J109 and it was flawless. The boat was sold and I have had no complaints from the new owners after a season of sailing including a 3rd out of 20 boats at the NA’s this fall after losing a tiebreaker for 2nd. But, as they say, your results may vary.

    Are Mount Gay Rum Hats Cool?

    Try asking Mt Gay, I did.

    Are Mount Gay Rum Hats Cool?

    That would be cool since they only started giving them out in 1986. I’ve got like 45 regattas worth of them in a big bag dating back to 1989. Have never worn one, they’ll go to Goodwill someday I guess.

    gyro autopilot compas heading

    Exactly the opposite. Apparent angle is affected by many things not the least of which is acceleration. If you start surfing down a wave the apparent will be pulled forward and a pilot steering to that angle will react to a “shift” that isn’t real by bearing off, possibly leading to an unwanted gybe. True values take this into account and result is far more stable and safe control of the boat in changing conditions. Of course this assumes a system that is performing calculations rapidly enough to matter. It’s true that many don’t but the good ones do and it really does matter.

    gyro autopilot compas heading

    Disputes all the words above the short answer is no, in compass mode all the pilot will look at is heading, with a gyro stabilized compass that heading input will be orders of magnitude better than a standard flux gate but wind shifts will not be considered. The other thing you should be looking for if this matters to you is a pilot that steers to True Wind angle not Apparent, far more stable.

    “Knot” a cool pun: worst boat names ever

    After 30+ years of sailing we went over!

    Upgrade/Repair Tacktick system or buy new B&G?

    Ditch it, even Triton is better than tic tack.

    Sure, no worries, here’s the story. For you and Rasputin. The NC11’s efficiency comes from the some of the same ideas thry’re using in modern cars, the engines are turbo diesels and she’s pretty lightweight for her length, 37.5’ loa @12,000 lbs compared to the similar length Backcove 34 @ 16,500 or 18,000 for the Beneteau Swift Trawler 35. Also very innovative use of space, that bench seat in the stern is on rails so you can have a swim platform or 2’ more cockpit if you want the space, it. Is forward in that photo. The salon also has a few different configurations you can set up depending on the circumstances. Living in Marina del Rey it’s an ideal Catalina weekend boat and the speed and cruising range, 300nm @ 23kts makes either Santa Barbara, the Channel Islands or San Diego easily reachable. That’s about as far as we will range. My wife has done two transpacs and owned three race boats and I’ve sailed 15 Newport Bermuda races and stopped counting when I hit 25,000 ocean racing miles many years ago, we’re not looking for extended range cruising. We’ve both seen plenty of blue water.

    Hi Bob, I think he was ragging on me not you. It’s been good to see the carbon cutter project progress, good work.
