We went to a boaters' beach in Belmont Bay. Shared the place with about 50 other boats and had a great time. Went over to our old stomping grounds in Mattawoman Creek only to find the 'beach' overrun with hydrilla. No boats anywhere. Weather was great, little breeze (just enough to pinpoint the 'knob drift' problem), and nothing but wakes over one foot. The new Yamaha ran like a top. One of these days I'll see how fast it'll push that Key West. We're still very happy with the boat. Oh, and I didn't feel too 'foolish' either! Knob drift? Yeah, the thing Harry was complaining about on Chuck's Island. The position of the knob, when going straight, will vary with the direction of the wind. It doesn't mean there's a hydraulic steering problem or anything else, although I suppose it could. Um....that's not a "problem" as such - it's entirely normal when adjusting for windage you will naturally turn into or away from windage changing the position of the wind. Remember you have what is essentially a bay boat with no real draft to keep you from moving when the wind gets up. - in particular if you are just "cruising" along at a relatively slow speed. You will have better control as you speed up. Eventually, your helm will make a 360 degree turn on you - the hydraulics aren't pressurized so there will always be some slop in the system and it will vary with air temp - even your console will have some effect on the expansion and contraction of the steering control's hydraulic fluid. That's one of the little annoyances of light hydraulic steering on small boats. In the eight years I've owned the Ranger, my helm has spun around 360 or eve more than that. Why did you opt for the knob? The wind is NOT the issue. Good grief. The wandering knob syndrome is normal for Seastar hydraulic steering systems. It's mentioned in the manuals that come with the steering system. Yesh - and who told you that? It wasn't the manual. And I'd love to debate the relative positions of the helm when steering into or away from wind, but I don't feel like it. Frankly, I don't know what Harry is talking about. Every boat I've owned with hydraulic or cable steering, from the Navigator, the Grand Banks, to the Scout and Boston Whaler will have different helm positions to compensate for windage while maintaining a course. Harry needs to take a ride on a boat with rudder position indicators, set a course, put the autopilot on and observe the rudder positions when running with wind on the beam. Eisboch Perhaps Harry has a boat unaffected by wind? Ethereal, perhaps? |

More on helm positions .... or semi-worthless nautical information .... I never knew this until we had the Grand Banks. By tradition, dating back to the great sailing ships, the helm had one spoke that was marked in some fashion to indicate that the rudder was midships when the marked spoke was in the upright position. There's a name for this mark that escapes me, but the Grand Banks carried on this nautical tradition. Here are pictures of the lower and upper station helms. In the case of the GB, one spoke had rings turned into it on a lathe to mark the midship spoke. They are indicated by the red arrows: The GB had cable steering. I can guarantee that the marked spoke would be in different positions when maintaining a steady course in different wind conditions. http://www.eisboch.com/lowerhelmmark.jpg http://www.eisboch.com/upperhelmmark.jpg Eisboch |
