Yours has too much drag from propellers and

Your local knowledge would certainly help in such confined waters, but remember that I
draw less than you do, even with you shoal draft keel. I don't have to reach my hull speed; I sail above your hull speed in 12 knots. I doubt your boat goes faster than mine in light air - even if you did get way on the first powerboat wake would set you rolling for 15 minutes. My props are folding, though I do have drag from saildrives and a bit of extra surface. I don't think you can add much sail. We both have 130s, and your 150 only adds about 30 square feet. I can carry my asymm a lot closer than you can carry your chute. The simple truth is that although my PDQ is not a speedster by multihull standards, it is substantially fast than most monohulls under 40 feet. "Simple Simon" wrote in message ...

The reason I would probably beat you in a race from Key Largo to Marathon is local knowledge (shortcuts, etc.) and unless there was enough wind for you to reach hull speed I would beat your boat because mine goes faster in lighter winds. Yours has too much drag from propellers and the extra wetted surface of two hulls. Also, I can hang proportionately more sail area than you can.

If you ever get up the nerve again to motor down the Ditch to Key West give me a shout when you get near Key Largo. I'll race you to Marathon and no motors allowed. You will be sooooo far behind. That is such a pathetic challenge - its hard to see how you could keep up with me for 5 minutes. For starters, my SA/disp is over 20, while yours is about 14.25. This predicts the speed, as a percentage of hullspeed, for a given wind. Meanwhile, my hull speed (not that I'm constrained by it, as you are) is about 8 knots. Your hull speed is about 6.3 knots. I don't have the Polar diagram for either boat, but lets try to do a VPP-like prediction, based on published data and tables. In a 14 knot breeze, a sail generates 0.02 HP per square foot. For you, that's 6 HP, or 1040 pounds/hp; for me that 10.8, which is 815 pounds/hp. This means (using a table) that you'll move at about 1.05 times the sqrt of your waterline, or 1.05x4.7 or 4.9 knots. My boat, on the other hand, will be at 1.14 x sqrt(WL), or 6.7 knots, or 36 percent faster. I'm not even considering that my boat goes faster than the table predicts, because of the very narrow effective beam of the individual hulls. Your boat will get to its 6.3 knot hull speed at some point around 20 knots breeze - at which time I'll be flying away at 10+ knots. At low speed, in a 10 knot wind you'll be at 4.5 knots; I'll be at 6.2 knots. BTW, these number are fairly good predictors - I'm a tad slower than the 10 knot wind prediction, a tad faster than the 14 knot. This makes sense, since at low speed the wetted surface affects me more than a normal boat; at higher speed I have less wave making resistance. You can talk about your 130 jib, but I have one too. Or your chute, but I have a new asymm. How about your main, is it a 3 year old modern full batten main or a blown out old bag? Do you have any chance? In light air anything can happen. And you certainly have local knowledge. Short tacking up a narrow channel would not be pleasant for me. Upwind, the margin might be a bit closer, though your shoal draft keel doesn't help you much. But on a relatively open course, in any wind over, say 8 knots, I'll be going 35% faster than you, or more. The last time I went by your mooring I was doing 8-9 knots, and averaged that for the entire day. Frankly, unless there's a dramatic change in my life, I don't think I'll get my boat down there again for a few more years (though I may be driving by at Christmas).

I draw 2'11" "at the dock," maybe an extra 1/2 inch with my normal summer gear, and about
3'1" loaded for a long trip. My draft increases inch per 800 pounds. Contrary to what you may believe, we are not over loaded - no genset, no A/C, no watermaker. Most of the gear was chose for weight and energy efficiency. Proportionally, your boat is probably more loaded than - you once bragged that you we overload enough to increase the waterline substantially. For example, while we both have positive floatation, mine is structural foam, yours is added weight. Even with your 170, your SA/disp is less then mine. My 130 bumps mine from over 20 to about 22. With the asymm its probably 25 or more. I don't need to pole out, with an 18 foot beam I just put a snatch block on the rail where ever I need one. I'd be pretty confident I'd blow you away in anything over 8 knots, but I admit, I don't often bother sailing in lighter wind. For most of my trips, bouncy around in the open ocean in a drifter isn't that much fun. Last week we went to P'town, over 50 miles. We were able to sail over in a 12-14 knot breeze, but coming back it was only about 6-8 - with the engines running the apparent wind rarely went over 2 or 3 knots. I'm sure you understand this - you talk about motorsailing all over the Bahamas. "Simple Simon" wrote in message ... Your boat probably draws about the same as mine. I don't see how a heavy multi like you sail can draw much less than three and a half feet. I have a 170% jenny that sweeps the deck and the clew of which is even with the companionway when sheeted in tight. I can go much faster than you in light winds and that is a fact of life. Even off the wind I can go faster because I can pole the 170 genny out on one side and the cruising chute on the other. My SA/Disp ratio can practically double yours on a downwind run. I would certainly be waving BuhpBye to you in anything but winds over about 10-12 knots. Your higher hull speed would only be an advantage in winds above that.

Sometimes one must use the engine, especially when there is a current
involved or one will arrive at another destination than planned. But, in a race where no engine use is allowed, especially here in the Keys, you would lose every time unless the winds were stiff. Local knowledge also means familiarity with currents which can be significant around here. Between my superior sailing skills and my more easily driven boat you would not have much of a chance at all of beating me in a race between Key Largo and Marathon unless it was wintertime in a norther.

Your local knowledge won't help since I could shorten sail and follow you anywhere. Then
I would simply sprint by you at the finish. I suppose if you call anything over 8 knots "a blow" you might have a case. Its a good thing you don't sail up here in the Fall.

The reason I would probably beat you in a race from Key Largo to Marathon is local knowledge (shortcuts, etc.) and unless there was enough wind for you to reach hull speed I would beat your boat because mine goes faster in lighter winds. Yours has too much drag from propellers and the extra wetted surface of two hulls. Also, I can hang proportionately more sail area than you can.

If you ever get up the nerve again to motor down the Ditch to Key West give me a shout when you get near Key Largo. I'll race you to Marathon and no motors allowed. You will be sooooo far behind. That is such a pathetic challenge - its hard to see how you could keep up with me for 5 minutes. For starters, my SA/disp is over 20, while yours is about 14.25. This predicts the speed, as a percentage of hullspeed, for a given wind. Meanwhile, my hull speed (not that I'm constrained by it, as you are) is about 8 knots. Your hull speed is about 6.3 knots. I don't have the Polar diagram for either boat, but lets try to do a VPP-like prediction, based on published data and tables. In a 14 knot breeze, a sail generates 0.02 HP per square foot. For you, that's 6 HP, or 1040 pounds/hp; for me that 10.8, which is 815 pounds/hp. This means (using a table) that you'll move at about 1.05 times the sqrt of your waterline, or 1.05x4.7 or 4.9 knots. My boat, on the other hand, will be at 1.14 x sqrt(WL), or 6.7 knots, or 36 percent faster. I'm not even considering that my boat goes faster than the table predicts, because of the very narrow effective beam of the individual hulls. Your boat will get to its 6.3 knot hull speed at some point around 20 knots breeze - at which time I'll be flying away at 10+ knots. At low speed, in a 10 knot wind you'll be at 4.5 knots; I'll be at 6.2 knots. BTW, these number are fairly good predictors - I'm a tad slower than the 10 knot wind prediction, a tad faster than the 14 knot. This makes sense, since at low speed the wetted surface affects me more than a normal boat; at higher speed I have less wave making resistance. You can talk about your 130 jib, but I have one too. Or your chute, but I have a new asymm. How about your main, is it a 3 year old modern full batten main or a blown out old bag? Do you have any chance? In light air anything can happen. And you certainly have local knowledge. Short tacking up a narrow channel would not be pleasant for me. Upwind, the margin might be a bit closer, though your shoal draft keel doesn't help you much. But on a relatively open course, in any wind over, say 8 knots, I'll be going 35% faster than you, or more. The last time I went by your mooring I was doing 8-9 knots, and averaged that for the entire day. Frankly, unless there's a dramatic change in my life, I don't think I'll get my boat down there again for a few more years (though I may be driving by at Christmas). Why don't you bring your fine bluewater craft up here next Summer? -jeff www.sv-loki.com "The sea was angry that day, my friend. Like an old man trying to send back soup at the deli." |

Jeff... don't be drawn into this silly exercise of having Capt. Neal claim
he can best your vessel.... he hasn't a prayer of challenging even me successfully and I'm certain your vessel is faster than mine on all points. I must admit however that he could in all probability easily beat a C&C 32 with Bob at the helm... lets allow him that.

I can beat a Westsail 32 any day and your heavy full-keeler is
slower than the average Westsail 32 by a significant amount. My beating Booby's boat is saying nothing at all. Booby's boat is probably faster than mine by a teensy margin but since he sails only using half his sails he doesn't have a chance even against a Seidelman or even the fine vessel depicted in this link: http://us.news2.yimg.com/us.yimg.com...boat_mh103.jpg "Capt.
