If I were to guess ... Greetings from Perth, Webb.<br /> If I were to guess about your mysterious drop in speed on tacking (and I am going to guess) I'd say it's a combination of current direction and wind direction that works well on one tack but not the other. If I'm right (and I'm not saying I am) then the effect would only be seen when comparing speed over ground on each tack, not when comparing speed through the water.<br /> Also, I may have a clue about why your tiller pilots keep failing. I was looking into using an electric actuator (like the ones on the tiller pilots) on a current project and I found that they all seem to be rated at about a 20% to 25% duty cycle, and it may well be that the motors are just burning up because you seem to only use them when you have no alternative - When they would be working the hardest. Most people are probably using them on calm days on the ICW, when they won't be constantly moving one way or the other. Let me know if you're interested in hearing more (I've been an engineer long enough to know that too much detail about these sorts of things bores most people.) ;)<br />Cheers,<br />KenKenhttps://www.blogger.com/profile/03334374556478322063noreply@blogger.com
