Catalina 275 Sailing Tips

I would like input from 275 owners on sail trim and modifications specific to their boat.

Make friends with one of the better sailors in your club and take him out to have a look at your rig. He may be able to give some tips on rigging and tuning. Racing against another C275 would be really helpful because then you could compare sail trim and match the faster boat. But you probably won't have that option. The mast rake is not really adjustable but you will want to check the tension of your stays. When I was healed initially, I had a little bit too much play. Still probably haven't figured out the correct tension, but it's better than before. That's been pretty much the only real modification I have done with my rig and I'm sure there is room for improvement.

I don't know the level of your sailing, but if you are not an old salt, you'll probably get bigger returns in refining your boat handling than in fine tuning.

I have been experimenting on down wind performance. The stock assym. becomes shadowed by the main on deep broad reaches. Heating the boat up and soaking does not seem to be a solution, so I have started using a whisker pole and sailing wing on wing. I used that method last week in our beer can race in 8 kts. of wind. The point of sail to keep it flying was very narrow, but it kept me competitive with the other boats.
Not wanting to purchase more sails yet, I am trying to make what I have work. The installation of out board tracks has helped with headsail trim when not hard on the wind. My self tacking jib is about six inches short of headstay after loosing the halyard mast lead. I have installed a short pennant on the tack which allows the sail to not be affected by the bow pulpit and allows the top down to lay under it when not in use. I know that a deck sweeping headsail is better, but the shape when off the wind is much better. Also, I have found that the top down assym. slows the boat down if it is left furled and hoisted, so I drop it as soon as I can.

Yes, ETNZ found that out when they left up their code zero for the short sprint from the start line to the first turning mark. In the first year, I would hoist before leaving the harbor, but I always knew this was not aerodynamic for the leading edge of the jib. Typically, I sail upwind when sailing and reach back to the harbor. Lately, I just leave the spinnaker coiled on the deck or haul the spinnaker out and connect before we get to the turnaround point. My wife made the below spinnaker bag for me this spring:

which will allow me to rig up the spinnaker and keep it bundled together until I'm ready to hoist. Should be able to see how it works in the next few weeks.

Codybear,
Another angle is to attach the bag to the mast base, with a quick release, so that the kite is ready to deploy. Here's how I did mine. (this way it can't escape while you're not looking...) It also make dropping it quite fast, the torsion rope coils nicely in the bag, the halyard clips nicely to the mast base, as does the tack line from the sprit, so it all launches from one spot.

Unfortunately, that is not an option with the self-tacking jib where the track is just in front of the mast, so leading anything back to the mast is problematic. My bag will sit on the locker hatch secured to the locker hatch handle and a stanchion to port. I put it on the port side so as to not interfere with the retractable spinnaker pole on the starboard side. There really isn't a lot of options for bag location with the C275 and the self-tacker.

Of course. The 270 is more of a traditional layout where you have to persuade the 155 manually. :) Food for thought anyway....

When I was doing my spring sail down and by chance I ended up wing to wing with the asymm. Went three to four miles, having the asymm shortly collapse four times. But with the right conditions and paying more attention than I was, you may get away without a whisker pole. I think the wing to wing gave me a reasonable downwind, but I'd have to verify this with more accurate comparisons using a GPS and a calculator.

I am considering purchasing a couple of new sails next year, a main and a asym racing spinnaker. My current and standard/stock main has all full battens. I race my boat in club races and am considering a radial cut sail with 2 full upper and 2 partial lower battens for improved ability for sail trim. Have any other owners replaced the full battened sail with a partial battened sail? If so, how do you like it? I am also considering a more performance oriented asym spinnaker, with larger area than the standard spin. I have been using the standard/stock spin for racing (without the furler) and think that I could do better with a larger sail. I would be interested to know other owners experiences.

On a slightly different topic, do any of you have a Performance Polar Chart/Table for the C275? If so, would you like to share it with the group?

Can't speak to the 275 yet, however I can say that I did prefer the full batten main to the partial on my Capri for cruising Feel it is safer as you have more control over the sail. That said, I also had a a North Milyar main with two full and to partial battens. The sail had a big roach that the second batten would touch the back stay with around a four inch overlap...

I found this Mylar sail performed better, speed and pointing ability, and as you point out because you had better control over the sail shape. The down side was it was really hard to optimize as the sail's sweet spot was real small, you were either on target of off...

I'd stay away from the $ of a Mylar main, as I think a Dacron one built like you said would be a great race sail

I picture fully battened sails being faster than partial. Certainly, something to discuss with at least one sail maker. If money is no object, how about North 3Di sails? Granted, that may be like putting lipstick on a pig.

Additionally, I was wondering if a code 0 would work on a 275. It would be nice to have a large sail for light upwinds.
