IMHO, given the cost of everything else that will need replacing, it wouldn't make sense not to replace the mast, too. It should be possible to find a buyer for the old one to offset the spend a bit.On a Selden in mast furling rig, if you were to convert to in boom like leisure furl or other would it mean a new stick as well?
The above from tane isn’t strictly true.
I’ve seen some rugged and not light weight cloth in boom furling sails. Most of the in mast ones I’ve seen are ‘light’ because they are almost a hundred years old and well worn out.
I scanned the leisurefurl sail-makers instructions online, and I didn't see anything regarding cloth weight. However, none of it made much sense to me so it could have been right there and I just dont know what I'm looking for...Perhaps things've changed in the past few years, but when I worked in a sail loft (15-20 years ago) we built two mainsails for boom furling (Leisure Furl and ProFurl).
Both specified significantly smaller, lighter, and thinner construction details (corner patches and batten pockets) than optimal. They also suggested cloth weights that were suitable for Great Lakes (i.e. lighter) than typical cloth manufacturer's recommendations.
Mainsail construction for mast furling mainsails is similarly compromised.
