Jeff has finally admitted the reasons why, for many sailing
enthusiasts, a cat like the PDQ 36 can't be considered. As a family cruiser platform it certainly offers a stable platform. But the tradition of sailing is what most of us prefer, and that included healing and the most important thing of all....Upwind ability where a multi faulters 10 degrees or more away from a boat like mine. On a long reach Jeff's boat is faster, but in any real race on various tacks, the PDQ couldn't even STAY ON the course. So...in Jeff's OWN WORDS, ladies and gentlemen... "It won't point too high (45-50 degrees true) but it will go upwind side by side with any cruising boat. Foot off 5 to 10 degrees, and it takes off like a bandit. Tacking is tedious, it certainly isn't good for short tacking out a channel. Light air is another sore point, because the large wetted surface starts to dominate. However, in 10 knots and over will do about half the wind speed. It continues to hold this ratio up to 12 to 15 knots of boat speed, depending on how long you hold off on reefing." And so...with winds below 10 knots MANY times in MANY areas, the PDQ gets an engine workout. With limited upwind performance the engines get another workout. 45-50 degrees is NOT ACCEPTABLE. I bet newer multis manage better. On the LIS these boats have to be motored much of the time and these are otherwise classic sailing grounds hosting some great sailing events. We see few Multi's sailing and for good reason...sooner or later you need to sail upwind better than 50 degrees! RB 35s5...the best performing boat here! NY |

You don't even know what a sailing race course looks like, or how one gets arund it. All he'd do is more tacks on the upwind legs - and then thrash the monohulls on the reaches and downwind legs. degrees! RB...the best performing clown here! 35s5 NY -- Capt Scumbalino |

gets arund it. All he'd do is more tacks on the upwind legs - and then thrash the monohulls on the reaches and downwind legs. That thing tacks like a bufallo for one. Second, he's not thrashing anyone unless he has conditions and wind to do it. The better pointing boat is the better performing boat. So it has been and always shall be. Tacks on the upwind even in reasonably fair conditions off a 10 degree deficit? Do you know how that would effect his VMG versus a high pointing monohull? And what of the more common light air? PDQ 36 is a cruiser with a very fast off the wind ability, but a performance boat it aint. RB 35s5...a real performance boat NY |

There's more to racing than going upwind, and more to even that than
simply pointing the highest. If you think otherwise, then you have no clue about racing. Hmmmm....seems few others agree with this. Even Loco and Steve have said the higher pointing boat has the advantage. VMG across the widest possible range is what determines perfomance. This is the essense of sailing performance in fact. Wish I'd written that! For a boat to be considered high performance it must have excellent windward ability, be fast off the wind and be stable downwind. A PDQ 36 is only fast off the wind and not in light air. It MIGHT win a race...so long as the conditions were pretty specific to it's advantages. My C&C 32 clobbered a well sailed Gemini even though it was faster downwind. Upwind it was a dead duck, just like Jeff's boat would be. He already wrote that tacking is tedious! Get a clue...even a PDQ owner says you're wrong. The PDQ and other cats like her are fantastic cruising boats for some folks, but sailing enthusiasts still prefer First series boats, J-Boats, Swans, Swedens and the rest who comprise the cruiser/racer-racer/cruiser section of the market. They're just more fun to sail, tack fast and can go upwind. RB 35s5 NY |

Hey, Jeff. Suppose you agree to go to the LIS to
meet bs (since there's no chance he'd ever go to meet you), and you accept his race challenge. It's blowing about 10k. He's beating to windward @ 36° making 4.7k - decent performance. But, you, with your loaded-for-cruising slug that can't point, foot off to about 50°, but in doing so are holding 6.5k. Yeah, you're faster, but you're not pointing. Then, down wind, he's sailing 170° making about 4.5k and you reach off to about 150° and are making just over 6k. Again, you're faster, but he's sailing closer to the mark. Can't you just accept the fact that his boat is better because he can point higher? S. "Capt. Rob" wrote in message oups.com... : That thing tacks like a bufallo for one.

Stop writing as if you speak for the rest of us.... YOU DON'T!
Then how come so many folks can afford a Multi and don't have one? Where's your multi? Where's mine? Where's Loco's? How come Doug says he's looking at a C&C and not a multi? Where's Bart's multi? Ganz seems to want one. Not me. Someone has to speak up for the group during hard times. Do you want a boat that is "tedious to tack?" Do you want a boat that "won't point higher than 45-50 degrees"? I am the chosen one, Skywalker! RB 35s5...the top performing boat here! NY |

On a long reach Jeff's boat is faster, but in any real race on various tacks, the PDQ couldn't even STAY ON the course. Finally admitted??? I finally admitted that cats don't point well??? And that's thats the best you've got? Booby, have you ever heard of VMG? Pointing ability is only one component of going upwind, speed is another. We don't have the polars for either of our boats, but we can make some guesses. Here's the polar for a Beneteau First 407, designed by Farr, and a much better upwind performer than yours: http://www.1stsailing.com/Boats/BoaI...hnicalData.jpg Speed at 45 degrees true tops out at a bit over 7 knots. Multiplying by the cosine of 45 degrees (0.707), we get a VMG (Velocity Made Good) of about 5. The Benny can point a tad higher, but if it loses even half a knot the VMG drops. The actual optimum point may be 40-42 degrees but there is actually very little difference between that and 45, except on the race course where pointing can be a tactical advantage. So how does this compare to a 35s5? The 407 has PHRF of 57 compared to around 130 for the smaller version, so that's over a minute a mile or at perhaps 10% on VMG. So the upper limit of VMG for the 35s5 might be 4.5 knots. Now, how about a cat? If we foot off all the way to 60 degrees true, VMG will be half of boat speed, so we have to do 9 knots, which the PDQ will do in 18 knots. Of course the comment of 60 degrees is fairly approximate, if the optimum is actually at 55 degrees, then the cat only has to do a bit over 8 knots to beat the monohull. Its pretty clear that in a breeze, the cat can keep up with, or even beat a Benny upwind. In lighter air the cat's speed will drop off faster, so upwind the cat will fall behind. But this is only part of the story. We haven't factored in leeway. The Benny may point at 45 degrees, but what's its actually course? Heeled on its ear, its making at least 3 degrees of leeway, considerably more if its puffy. At 3 degrees the hit to VMG is 5%, at 5 degrees the hit is over 10%. In fact, on a puffy day, it takes considerable skill and attention to get the most of the Benny. The cat, on the other hand, will be going flat and fast at 60 degree true, with minimal work. A number of times we've blown past a mono stalled out in a puff, heeled over, making maybe 15 degrees leeway, sometime worse. So what's the true break even point? It would depend a lot on the conditions. In protected fla****er and steady wind, it might be 16 knots, add a chop and puffs and it might be 12 knots of wind. With a full crew in a race the benny might do better; shorthanded the cat is easier to keep moving. On a small race course, a mono certainly has a tactical advantage, but remember that the small version of my cat races at a PHRF equivalent of about 104. This is before we take into account Bob's primary claim, that most people prefer a boat the heels and goes upwind as fast as possible, especially in light air. Frankly, I don't care what "most" people prefer, I only care what suits my needs. Certainly, if your sailing is limited to a few hours of daysailing, its understandable that you want to get the most "sailing" out of it. In fact, I sail at a local club where I can take out a racing dink, or more likely a Rhodes 19, so I can do some daysailing and get the real "experience." But my purpose in having a larger boat is to go cruising, which usually means traveling 100 miles or more to interesting destinations. I have no desire so spend a whole day heeled over 40 degrees, or making 2 knots VMG upwind in light air. In fact, I never heard a cruiser say they want to heel more, and there are rather few that will "take what comes" and wander around in a drifter. Go ask at any cruising anchorage and you'll that 90% of the would prefer to sail flatter, and most would fire up the engine when the VMG goes below half of their normal "good" speed. So...in Jeff's OWN WORDS, ladies and gentlemen... I know what I said, and stand by it. Does Bob know what he's talking about? Doubtful. And so...with winds below 10 knots MANY times in MANY areas, the PDQ gets an engine workout. So would many other boats. Do you have a point? Cruising boats often don't do well in light air??? What a revelation!! With limited upwind performance the engines get another workout. 45-50 degrees is NOT ACCEPTABLE. Then you better get rid of your Bendy, because it doesn't do significantly better than 45 degrees. You really don't know anything about sailing, do you, Bob? I bet newer multis manage better. Sure, lots have daggerboards. In fact, you could buy my boat with daggerboards. I didn't have that option at the time, but it isn't something I would want to sacrifice convenience and interior space for. Raising the VMG from 2 to 3 knots doesn't mean much - I've freely admitted I probably be powering at 8 knots in that case. And so would most other cruisers. On the LIS these boats have to be motored much of the time and these are otherwise classic sailing grounds hosting some great sailing events. We see few Multi's sailing and for good reason...sooner or later you need to sail upwind better than 50 degrees! Gee, do you think maybe that's why I said this boat is an appropriate choice for you? I'll say it again: A Beneteau 35s5 is possibly the best boat for someone who only sails 5 miles from his slip in light air. Are you happy now? RB 35s5...the best performing boat on LIS, but not anyplace a real sailor would want to be! NY |
