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. Who told me that? A "techie" guy on a real boating discussion board, who backed up what he said with a quote from the manual. Your "techie" is full of it. Hydraulic systems are capable of very fine and repeatable positioning due to the non-compressibility of the fluid. They are used often over cable or pneumatic systems when fine positioning control is required because they overcome the "sticky" nature of pneumatics and the stretching of cables. In the business I was in we used air over oil hydraulic systems to precisely move and locate 500 lb objects to within thousands of an inch. If the hydraulic steering system has not been purged of all air, or if there is a leak, I can accept the helm position non-repeatability. But, if leak-free and purged of all air, it should be perfectly repeatable. It's the cross wind. Eisboch Hehehe. Sure. We're talking a fairly "el cheapo" boat system here, fella. In the business you were in , your air over hydraulic system cost a bit more than half a large. |
