Proper Fender Placement
For the best protection:
- Tie fenders to a stanchion base, deck cleat, or secure rail.
- Avoid hanging fenders from lifelines, as this can place unnecessary stress on the lifelines.
- Position fenders so they just touch the water's surface when deployed.
- Carry at least three fenders for most recreational boats, with larger vessels often requiring four or more.
