Not an "expert" but I've been an avid amatuer for 20 years. I currently use a Celestron 9.25. I do most of my observing in PA where darker skies still prevail. I used to use a Dynascope RV6, Celestron 8 and Questar Duplex. I've used a lot of scopes and do consider myself an armchair expert when it comes to scope buying. RB I have a 16-inch newt mounted in a truss-tube Dob assembly. I'm a member of the NASA -JSC astronomy club and have been attending the Texas Star Party for several years, held annually in the spring in west Texas. I also have one the new Meade autoguided systems. I'm hoping to finish the Messier list this year. - Don't think this would work on a boat, but binocular observing should be good off shore. Jim |

No he is not.

If you can or can't prove it, then he will claim he is.

SA/D is generally based on a 100% jib, unless otherwise indicated. It's just
one additional piece of the puzzle when roughly predicting how a given design will perform. http://www.sailingusa.info/cal__sad_ratio.htm RB |

If you know how to interpret the #'s, try this instead, they do most of the
calculations for you. http://www.phrf-nb.org/year2002/ratings/PHRFratings.htm John Cairns "Jim Cate" wrote in message ... After all the interesting, thoughtful, considerate, helpful, balanced, discussions regarding the Mac26M, I'm still looking at different options. There seem to be some great buys on larger boats in our area, and in the same price range as the Mac 26 or lower, there are some nice boats in the 32 to 34 foot range. I prefer a responsive, relatively fast coastal cruiser rather than a heavy, ocean passage blue water boat, and the Cal 34's and O'Day 34's seem to meet those requisites. There are also some C&C's, Catalinas, Columbias, Hunters, etc., in the same general price range, and others, such as the Sabres, Newports, Benetau, Cheoy Lee, etc, that seem to be more expensive. As far as cruising speed in typical ( e.g., 15 - 20 knot) winds, under full normal jib and main, average load, and equally experienced captains, etc., would there be a significant difference in speed or handling between the Cal and O'Day, both being in good condition and similarly equipped? The (1978) Cal 34-III has a waterline of 26 ft, and the (1983) O'Day has a 28'9" waterline, according to the spec sheets. Plugging this into the formula (square root of wl times 1.34), I get a predicted hull speed for the O'Day of around 7.185 knots, and 6.833 knots for the Cal. In actual practice, would this be close to what I would see under most cruising conditions? The O'Day, at 11,500 lb., is slightly heavier than the Cal and has a draft of 5'7", LOA 34, beam 11'3", compared with 10,200 lb., draft 4'9", LOA 33'6", and beam 9'3" for the Cal. Can anyone provide some comments on or comparisons of the sailing characteristics of these two boats? It's my understanding that the Cal may be somewhat more of a racing boat, responsive but a bit more tender, and the O'Day may be a little stiffer but steady under heavy winds. For example, I recall seeing over 9 knots on a 40-ft Valiant we sailed in the Gulf under 15-20 knot winds, which I think was more than its predicted hull speed. Comments, suggestions, or recommendations regarding these or other similar boats will be appreciated. Jim |

Jim,
The Cal will do a horizon job on the O'Day. That doesn't mean the O'Day is a Slug. The Cal is a pretty fast boat. I've sail in a fleet with a Cal 34 sail by a club member. He put new sails on her and won the "TransPac" overall on handicap. It is also a better built vessel and cruises well. So does the O'Day ( Cruise Well) but in my mind, the Cal is a better boat. As you say, the O'day is roomier and it certainly not a badly built vessel. It may be the but for you. They don't have to apologise for quality or sailing ability but isn't in the same class with the Cal 34. Ole Thom P/S got your post about "The Institute" I'm afraid I am quite a bit before your time. My biggest memory is the Library there and the thickness of those wall at the Gun port/windows. Ole Thom |

I wouldn't argue with your claim that the Cal is better built than the O'Day,
which I've always considered a notch or two below Pearsons, etc. in quality. But I'm not sure the Cal is faster in general conditions. In fact, its PHRF is about 20 to 25 point higher. I think the O'Day would hold its own very nicely, while giving a more comfortable ride. "Thom Stewart" wrote in message ... Jim, The Cal will do a horizon job on the O'Day.

O'Day build quality varied a lot over the years. Actually so did Pearson, they were each owned by several different companies over time and built in several different facilities. The O'Days I have most experience with are the smaller ones, except for the center cockpit 37. That boat is built very solidly, but the details and fitting out leave something to be desired. Some of their smaller boats were quite well done. Others were flimsy crap. Seemed to vary widely and I don't know what years (or corporate ownership) were the good ones. In general, I agree that Pearsons are a bit above the average for mass-produced boats, in some regards. Cal also, and more consistent... But I'm not sure the Cal is faster in general conditions. In fact, its PHRF is about 20 to 25 point higher. I think the O'Day would hold its own very nicely, while giving a more comfortable ride. The O'Day probably has a considerably more optimized cabin layout too. They adopted some innovations that Cal ignored. Fresh Breezes- Doug King |
