Yours was a very interesting reply to my post, as I am sure that there is an E D(?) Gadd listed as a previous owner of the boat! (No 1720). I presume that they are the same person.
The arrangement that you suggest certainly makes a lot of sense from the fittings that are on the boom, but I was worried that there would be some snagging if the line to the sheets was pulled in before the pole went out, something that seemed certain to happen.
If anyone knows where Ted Gadd is and can put us in touch, I would be greatful.
P.S. I will try to get the pics of the poles posted, I have been having problems with the card reader for my digital camera.
