Re: How high can you point?

This " " High!

Everything, but everything contributes to pointing ability. One of the best (most concise) write-ups I came across was here:
Catalina - Capri - 25s International Association

Yeah it's written in VERY basic terms, but it's a great pre-read to some pretty heady material that this subject usually brings up.

Depends on how your tabs are set up. Mine are not 90*, they're closer to 70* from each other. And the wind vane is reading apparent angle, not true.

I works like a charm. As I start to head up, the sails will luff just as the vane hits the tab. If I keep the vane in between the tabs, all is well. It also works well for people learning how to helm while reaching.

So, to answer the OP's question: On my boat, the way I sail it, 55 degrees.

Lets stick to talking about the angle we tack through, as that is a much better measure of how a boat points.

Some of the things that effect pointing are:
bottom condition and foils
boat speed
sail condition and cut
rig tension
heel angle
sail trim
weight placement
GPS angle is what counts, with adjustment for current. Wind angle is interesting but slightly off the point.

Eventually, VMG is mostly what counts, though pure pointing can count if space is limited. This will require a little trig, unless you have some cool electronics, but you learned it in high school. Sometimes 100 degrees is faster than 80 degrees, sometimes not; it can depend on waves etc.

I can bench press about 220.

Re: How high can you point?

Furling the sail at all will have pretty negative effects on your pointing ability.

Re: How high can you point?

The headsail is a 130% dacron sail on a roller furler. It is a little baggy, and it is probably contributing to the boats poor pointing. The trades blow pretty well around here (Oahu), and we often have it rolled up partially and put a 3rd reef in the main. I will try to move the traveller to windward and see if that helps. I can feather up a little once I'm at 100 degrees. I will take her out again and make an accurate assessment using my GPS. Thanks for the responses.

Did you tack to check (by comparing compass directions). That won't demonstrate leeway, but at least gives you a ballpark number compared to true wind.

Apparent wind angle readings can be BS too if the boat is well heeled and the air is spilling off of the sails up to the wind instrument.

When I'm really curious I'll start a GPS track, tack, check the new track, then tack back and see what the angles look like. Of course this can be affected by tidal currents. It does feel great when you are short tacking with the current and have a GPS track that makes it seem like you are taking through 60 degrees.

I had a Catalina 25 that seemed to point better than most of them (based on the races that we entered), and we rarely had tacks much under 90 degrees. The Catalina 27s that I've raced against seemed to behave similarly.

You mean the traveler or the boom?
