Can anyone tell me what the correct distance is for the boom above the deck at the mast on a 1884 tall rig?

If it's a schooner, I'm thinking 7 or 8 feet, but I'm not sure for a clipper.

Assuming you mean a 1984 C-25 tall rig, (the C250 didn't exist until later) the [url="http://www.catalina-capri-25s.org/manbro/Cat25manpre88.pdf"]Owner's manual, page 14[/url] tells us that the "I" measurement is 31'. The luff of the mainsail (on the same page) is 27'4". So, with my limited math skills, the difference would be 3'8" for the height of the boom off the deck at the base of the mast. Well, more precisely, the foot of the sail at the top of the boom.

It also depends on your mainsail size and stretch. You want the main sail to have a proper shape. I'm assuming you want to figure out where to adjust your topping lift when at rest? You want your topping lift adjusted so that with my main sail up the topping lift starts to slack off (1-2 inches is enough). If you don't care for that extra .1 - .3 knots, then you can adjust it so the boom passes right over your head when at rest. I'm 5'10" and the boom will clip my head with my current adjustment. However I installed a bimini last season and the boom passes just 1" above it when deployed.

Guys, the question was how high off the deck, not off the cockpit sole. Besides, he has a C25 Tall rig. Different dimensions than either the C25 Standard rig or the C250.

Okay wise guys. I've got a 1984 TR. I haven't taken a tape measure from the boom to the deck house roof or to the cockpit floor, but I can tell you this. I generally raise my main fully and can tension the downhaul to set the boom/gooseneck just about an inch below the mast gate.
Hope that helps.

P.S. John R. Isn't the I measurement along the forestay? The TR has a 30' stick, so 30' minus 27'4" equals 2'8", not 3' 8" above the deck.

I checked the owners manual today. The P measurement (which approximates the luff length of the main) is 27.66' or 27'8". allowing about 2" for the boom itself, the boom should stop about 2'2" from the cabin roof and about 2' above the sliding hatch.

Hal: Since you posted on the C-250 forum, did you mean 1995 instead of 1884 (one key off)? They did make a few tall rig C-250s around that time.

I checked his profile. He has a previous post about a 1984 tall rig.
