Hi Yordan
and welcome to the JRA.
Firstly you will find lots of help and advice here. And of course lots of different opinions :-)
It might help if you tell us what sort of sailing you are planning to do? Offshore? circumnavigation, coastal cruising? live aboard?
I can't help you with 'Rose' I'm afraid and I think she has been for sale a long time. Looking at the description it says she has hinged battens. I think these have been found to not work well as a method of adding camber to the sail.
You have a folksong and if you're planning to sail long distances I would think she is a better boat for the job. I have a Contessa 26 and I believe her to be a better sea boat than a Hurley... but of course that is just my opinion.
I am based in Plymouth and there are several junk rigged boats here. Perhaps you could sail over and look at the options. If you decide to convert your current boat I can let you have a sail on mine and see what you think before committing.
Best of luck
Peter
