My 25 Tall rig has been a problem since acquiring the 25 last year. The boom swings across at head height with the sail fully raised and no further halyard adjustment allowed. Was advised the result of the sail being streched (it is a 1986 product) causes the boom to be so low. I took the sail to a sailmaker who examined it and said the material was still in good condition but the rope on the luff had streched and needed replacing which would enable the leach to effectively lift the boom up and provide head clearance. After putting it back on the boom still is too low. I wonder if the original design of the sail did not allow a higher boom height. If that is the case than the only real solution would be to reduce the luff length by 8-10" thus allowing the sail to be raised higher. This would provide reasonable head clearance in the cockpit area but means losing some sail area square footage which would have some effect on the sail ability to perform to original design specs.

I would appreciate any information on this condition.

Hi Alice,
I am surprised you have not discovered your answers in the documentation and manuals area of the site or by searching the forum. Your boom is where it is supposed to be. The term tall rig is a bit of a misnomer, It should be stretched rig. The mast is 2ft higher but the sail luff is three feet longer; the boom is 1ft lower as a result.
It would seem your sailmaker is very lazy, this info is in his database.

The boom is a foot lower on the tall rig than on the standard rig, and that gives you extra sail area, which is a blessing on light air days. Those of us who have tall rig boats become accustomed to the low boom, and it's usually no problem. There are times, however, when you want a little extra clearance, such as when cruising, or to install a bimini. The easy and inexpensive solution is to have your sailmaker install a reinforced flattening reef grommet in the leech of the sail, about a foot above the boom. Use your reefing line to pull the grommet down to the boom. When you do so, it raises the aft end of the boom a foot, giving you extra clearance in the cockpit. If you need extra sail area in light air, you can always let out the flattening reef.

Or, you can have a sailmaker (and I'd recommend a different one) shorten your sail either by raising the foot or lowering the head. I found that a Capri 25 sail, which you might find used, raises the boom sufficiently to install a bimini (http://www.catalina25-250.org/forum/topic.asp?TOPIC_ID=6903).

I dont have that problem. I bought a 25 tall rig that still has
standard rig sized sails.

Changing that by next nationals though. Nothing like trying to keep up with other tall rigs when your sails are much smaller.

Sounds like if I ever race against Milby that I need to buy much much much larger sails to even stay close!
