Although the sails are 22 yers old and there are repairs on them they can be still good if they were not used. Tears might or moght not be a pronblem .If they teared due to wind force they might not be in good condition. But if they get defective during hoisting due to mishandling they might be still in good condtion.
Leaks in ports and hatches should be easily repairable.
Stachion damge to the fiberglass can also be repaired without too much problem.
The vibration of engine in a specific level is most probably due to misalignment. You cannot feel the misalignment with moving the shaft or propellor with your hand. It should be checked and aligned.
