Hello everyone!
Good question!! I'm literally on the same boat. My situation is a bit easier however, in that the boat itself is pretty much structurally ready. Details are:
Boat: Freedom 30 cat ketch. This is a Garry Hoyt design from the early 80'; i.e. unstayed carbon fibre masts, main and mizzen almost same length (mizzen shorter by less than 2 feet).
Current rig: Wrap around 2-ply sails with Wishbone boom... a system I dislike...
Future use: coastal sailing around UK and Atlantic seaboard within the next two yrs, but bluewater trades sailing thereafter - when I can finally retire :) !
Option 1: Replace current 2-ply sails to modern single ply sails the boat was designed for, and maintain wishbone rig. Budgetary estimate for new sails including bag, battens, etc: ca. GBP 3000
Option 2: convert to Junk rig. Budgetary estimate for conversion (from rigger that has already converted two Freedom 30s - exactly the same boat) was GBP 10.000.
Now, converting my boat should not be too difficult... no structural modifications required, masts should take identical sails, so cost should be related to sailcloth, battens, running rigging, and labour.
I know there's a lot of labour in constructing and fine-tuning the rig, but at the same time, 7000 quid delta buy a lot of performance and safety for the boat in other areas, so I'm thinking very, very carefully about it.
Any input from Freedom owners (I know there are a couple of them in this forum), or comparable boats, would be extremely useful and very much welcome.
Thanks
