With the sailed rinsed/washed and dry, it's worth checking each one for:
- Damaged/broken stitching
- Damaged corroded cringles and lacing eyes
- Cracks in polykote sails.
It's not difficult to repair most problems like this. You can just re-sew, either by hand or machine short sections of stiching. Damaged cringles are best removed and replaced (cringle kits are available). Holes can be patched, you local sailmaker will often have a suit red polyester sailcloth and will sell you an offcut. Spinnaker repair tape is stocked by a lot of chandlers. You can buy sticky backed polyester material, which stick on sail numbers and letters are made from, in a variety of colours from your local sailmaker. This is very useful for patching, making numbers or sticking on tell tales. In some cases (e.g. a hole in a batten pocket), just a stuck on patch may be fine.
Polykote sails are prone to cracking along the weft or weave of the fabric. Often this happens were stress is concentrated for some reason. Along the edge of a sail number or letter, along the bottom of a jib where reinforcement ends are common locations. I often use sticky backed polyester for these repairs, or a soft red sailcloth. Sailcloth patches, or sticky backed ones on jibs need stiching on.
This is probably a good opprotunity to change the sail numbers or national letters on you mainsail if they are not the correct ones.
