Jerry, Ye of little faith! With a safety factor of 8-10, you should have total confidence. My boat is not in fact one of yours, but I imagine the specs are about the same. Thanks for all your input. Tom Jenkins 2004 M17 Scintilla On Dec 2, 2009, at 4:43 PM, jerry wrote:
Tom- If you're talking about one of my boats, and by ring you mean the U-bolt bolted thru the stem, it would lift 8 or 10 boats. (Don't stand under them, tho)

Joe, I had no movement of the ring in winds over 30 knots at the mooring, and I always assumed that the sharp angle at the bow made the strongest part of the boat. I tried to slide my boat a few inches across the bunks with the trailer winch (dumb), and it flexed the upright 2" without sliding the boat, and the ring held solid. Anybody try to hang a 17 from a crane on the trailer ring alone? That is the real experiment (preferably with someone else's boat!). Tom

Tom, I did notice that the 'sailing' did drop off considerably with the bridle but didn't eliminate it entirely. I think you have something here. Also I think the relative light weight allows her to more affected by winds and currents. Just another one of those trade-offs when I downsized from a NorSea. Are you comfortable with the amount of backing on the tow ring to anchor off of it??

Joe, I think "sailing back and forth" is a function of the curvaceous airfoil-like hull shape rather than the direction of pull. I moored for a couple of months with a line clipped to the trailer ring, and the boat still "did the dance" in stiff winds. Fastening low on the boat does reduce rolling a bit, however, and I think it is easier on the hull. Tom Jenkins

I'm assuming that there are two reasons for wanting a sprit. One, to hold the anchor in place when sailing and second to keep the anchor line running dead center off the boat when anchored to eliminate "sailing". I agree with Sir Jerry about the anti ballast. I still had a problem when I ran the anchor line one of bow chocks because that little bit of imbalance created that annoying sailing back and forth. To temporarily remedy this annoyance, I took a short piece of line and tied a rolling to the anchor line about 2-3' off the bow and ran it back thru the opposit bow chock; tensioned it up enough to balance the pull; and, cleated if off on the deck cleat. Eventually I would like to mount a SS bow roller. But I'll still keep the anchor in the port cockpit locker. I get a lot of strange looks and comments about the "stern deployment - walk the line to the bow" method of anchoring but with no anchor line locker up front and no intensions of making one, I'll just have to take the weird stares.

Another thing to think about is that the sprit, and having the anchor that hi, is anti-ballast and will make the boat more tender. Salty looking, but not practical in my mind.
Sorry
