Tips for a Successful Purchase- Check the Maintenance History, especially for models over 10 years old (keel changes, rudder, engine).
- Inspect the Hull and Deck: osmosis, delamination, watertightness of the bilges.
- Examine the Rigging: condition of shrouds, cables, winches, and sails (many SLY 42s are under-canvassed).
- Test Electrical and Electronic Systems (risk of corrosion in saltwater).
- Request a Sea Trial to evaluate trim, sailing performance, and engine.
- Prioritise Listings with a Navigation Certificate (CE inspection or survey by a marine expert).
