Its too rainy to go sailing or go to the beach, so I looked at T34c's on Yachtworld, and looked up the rig dimensions.
I thought Jeff's figure of 3-4,000 lbs mid-boom main sheet loading seemed a little high. I used 30kts of wind, approx the apparent wind speed when sailing upwind in 25 kts, a point beyond which most of us would be reefed, but not uncommon for a gust on an unreefed main. I used the 10.5 ft boom length, but readily grant that many T34 booms are longer.
Using the formula E square times P square times 0.00431 times wind speed squared divided by (the square root of P square +E square) times distance from mainsheet attachment to tack of mainsail, I come up with 2650 lbs, close to 3000 lbs but a ways from 4000.
I notice that many of the boats for sale on Yachtworld have a house top traveler. (Also wheels are common, but I believe a wheel was a factory option)
Perusing the T34 owners group website posts, I would say that most of the T34c owners with house top travelers are happy with them.
That said (as my mother used to say) just because most people are jumping off the cliff dosen't mean that you should.
Obviously I don't have anything better to do today than argue a little bit with Jeff. (Maybe I should be in church) But I still believe a properly done house top traveler can be a viable system for a T34, and might be preferred by some cruisers. "Properly done" would include increasing mainsheet purchase, spreading the boom attachment over 2 or 3 points, and reinforcing the house top. The most commonly used traveler seems to be Harken's big boat system.
