The tall rig's larger sail area makes it considerably faster in light to moderate winds, but as the windspeed increases, the difference decreases. At about 20-25 kts., the performance is about the same. Above that windspeed, the disadvantage caused by the tall rig's additional weight aloft overrides the sail area advantage, and the standard rig performs better than the tall rig, because it points higher and heels less.

In short, the tall rig is a better light air boat, and the standard rig is a better heavy air boat.

my good friend Gary has a tall rig, I have a standard. With his 110 jib on and me with my 135, we can sail side by side for hours and hours. I wish I had the tall rig on light air days, but on my standard I can throw on my 170 jib and keep up or even pass. On big air days I have a decided advantage. The tall rig mast is 2 feet higher and the boom 1 foot lower. The tall rig boat is more tender and you have to reef earlier. Reefing the tall brings the main down to the size of the standard, so on a tall you should have two reef points.

On an average 15 knots of wind day there is not much difference. I'm happy with my standard rig.

One thing, there always seem to be more used tall rig sails available.

The Tall rig has significantly better performance in light air. I have owned C-25's with both rigs and comparing the two, I can say that in a 2~3mph breeze, the SR will be practically dead in the water, whereas the TR will at least have steerageway, maybe 1 knot of boat speed on a close reach. The TR has some other disadvantages though:
1. Your adult guests are more likely to get their skulls "bonked" - the TR boom is so much lower that I sometimes get hit myself even though I've had the boat for three years and ought to be used to it by now.
2. If you install a bimini, it has to be cut down so much, to fit under the lower boom, that it can be quite difficult to climb in and out of the cockpit, like in a raft-up where people are visiting between boats.
3. Raising and lowering the TR mast takes significantly more effort. It is not only 2 feet longer than the SR, but is 1/2" larger in depth and width of cross-section, and 1/32" greater in wall thickness, resulting in about a 30-pound heavier total weight. The C25 TR mast is in fact quite similar to the extrusion used on the old C27. Doing a mast raising on a C-25 TR, I recommend at least one or two experienced helpers, and a stout gin pole or A-frame. Also, be aware that if you use a mast crutch that sits inside the stern pulpit, the center of gravity of the TR mast in the lowered position will be about 12~16 inches AFT of the crutch roller, meaning that the masthead will want to drop and the foot pop up (maybe hitting you in the face) as soon as you pull the tabernackle pivot pin. To mitigate this problem, I fabricated a mast crutch that mounts behind the stern pulpit and leans backwards at a 15º angle, so that it catches the mast aft of it's balance point. The weight is fully supported by the mainsheet traveller, and there is a pin on the bottom that sticks into the lower gudgeon for lateral stability (but carries no weight). There are also a pair of diagonal braces made of light weight conduit that run from the top of the crutch to the forward end of the stern pulpit to prevent sway. I can send photos and a design drawing if anyone is interested in building one for their own boat. I trailered 1900 miles r/t to the San Juans cruise with this crutch and it never shifted position.

Ed I think that there's more to the tall versus standard rig than simply comparing the rigs themselves. The type of keel comes into play as well.

A fin keel tall rig will be somewhat stiffer and can carry more sail under conditions of higher wind than a swing or winged version.

Over the last 22 years I've found that I can usually keep up with my sailing buddies in moderate winds while using my 110% jib when they've hoisted their 150s and my boat has been stiff so long as I've selected both the proper jib and reef settings. (I'm still an old fashioned "hank on" guy.)

When I use my 150% jib it's usually no contest and I doubt if you'll be doing much of your sailing in winds over 25 knots unless you're in an area where high winds prevail in which case a standard rig is the way to go.

Anyway, with a standard rig you can always hoist your "womper"(you hoist it up and it goes "womp" and you'll sail right past everyone).
