Thanks for the response Island Time, very good points! I'm looking at this one- https://www.trademe.co.nz/a/motors/boats-marine/yachts/keeler/listing/4019764571
It hasn't had Cat 1 as far as I'm aware, but plan to spread the upgrade costs over the years I remain in NZ. What are the big ticket items for Cat 1 that I'd need to budget for? I'm already factoring in the additional safety gear, storm sails and replacing standing rigging and lifelines. What other major things I would need to consider?
