hi everyone, just purchased a 85 standard rig, very excited!! three questions for all you gurus out there:

1) What hull speed can I expect?

2) How well does this rig perform in light air (I have a roller furled 150)? I sail on Lake Erie, which can go from 3 knots breeze to 40 knots in the course of 10 minutes, but light air is frequent as summer looms on.

3) My main I suspect is a problem, it measures 24.75 feet X 8.75. I realize this is a foot short on the foot, but being a masthead rig, do you thing this will have any real effect? I will purchase a new main for next season, but how do you think this main will work for this year?

Thanks, looking foreward to great sailing on my new 25!!!

Your main should work out fine. If its a foot short it should give you a little more stand up room in the cockpit. 150 on a furler will be OK to. Have a good season and see you on the water. BTW how about some pictures ?

Welcome aboard LanceJ... I hope there are lots of good times ahead for you and your vessel.

Here's a link for specs on these boats. Hull speed is about 6.31 kts.

Congratulations, Lance...Welcome to the club! <img src=icon_smile_cool.gif border=0 align=middle>

If your current main is in reasonable shape, you probably won't notice much of a performance difference with that of a main that has 9" more in the foot. On the C25 most of the power is generated by the headsail and your roller furled 150 will move your boat quite well.

Just yesterday I was out on Lake Erie beam/close reaching in a following sea in winds of 10-20mph with just my 140 genoa up(main was lashed to the boom) and I was attaining speeds of 6.5+ knts.

Where on Lake Erie do you sail?

Welcome, Lance--great choice, the year and the rig! <img src=icon_smile_wink.gif border=0 align=middle> By short on the foot, I gather you're referring to the boom being at least a foot longer than the foot of the sail. That's by design, putting the mainsheet out closer to the traveler for better purchase, and to reduce lynchings of the helmsman during tacks (and worse, gybes). Some people have used a sail from another boat (Ranger?) that has a longer foot, but I doubt that it gives them much more power. (And it should change your PHRF rating if you race.) Others have bought full-battened mains with larger roaches that tend to hang up on the backstay, but do add some power.

Tell us more--your name, keel type, auxilary power, and interior. You can record those things permanently in the "signature" that is displayed with each post--notice mine below.

Also, think about a $20/year membership to support this site and the organization that makes it possible. It's the best .2 boat unit you'll spend on her!

Thanks guys, I'll get some pics soon! I sail out of Buffalo, at the very west end of the lake, consequently large changes in water level and big waves in relativly light winds. It goes in the water today, very excited!!

Lance,
No one has really replied to your question about C-25 performance in light air. After sailing one for 24 years, I would say the C-25 is somewhat of a "dog" in light air. The boat is really at its best in about 10-14 mph with a good 150% genoa, reducing headsail size from there as the wind increases. Up wind the boat is really good in these conditions, off the wind the bigger boats your were beating will catch and pass you. The boat does not have a high aspect ratio/huge sail plan, so light air is really not its forte.

Steve - Thats an understatement.....Its a big fat slow dog in light air. Anything under 8kts and I put up the iron Genoa.

In under 5 knots, we hoist the light air, beat-up 155%, everyone sits to leeward and we keep ghosting by most of the other boats...but we don't try to point! One advantage of the TRFK. <img src=icon_smile_wink.gif border=0 align=middle>

I agree with Derrek. In light air with a monster headsail I also pass a lot of boats. I slack all of the contol lines (halyards, sheets, vang, etc.) and set the crew on the lee rail with full beverages so there is as little movement as possible. I would hardly call the C-25 a dog in these conditions. It's when the wind is howling and the sea's are big and steep that I suffer against bigger heavier boats. I also sail a tall rig, maybe this makes the difference in light conditions.
Regardless of where or when you sail, enjoy and be safe.
