Torn the mainsail whilst putting a reef in.
According to the survey report: condition of the sails is in accordance with their age.
The sails are 18 years old. 🤔

I you were buying a boat and you knew the sails were 18 years old, would you need a surveyor to tell you the condition of the sails was 'not great'?

Provisionally 'fixed' it with duct tape - your friend in need.

I guess new mainsail just moved to the top of my 'things to replace' list.
