Fit Notes & Sizing Guidance
• Boats with a traditional pointed bow can be secured using the included straps looped under the bow (see product photos).
• If you want additional coverage over the swim platform or plan to stretch the cover over a lowered tower, we recommend ordering the next size up.
• When fitting over a lowered tower, small side gaps may be present, but overall coverage remains effective.
• Excess strap length can be trimmed to your preferred size after installation.

3. Secure at mid-ship cleats if desired
4. Continue stretching the cover over the transom furniture
5. Attach rear straps to transom eyelets, cleats or swim platform hardware

Installation typically takes about 60 seconds once familiar.
 
Please note the Black Cheetah and Desert Grey Camo printed covers will fade in prolonged sun exposure but can be flipped over to a solid light Grey color if desired, we recommend these prints for indoor and covered use.
