Actual Fabric Measurement
While using the centreline length and widest beam is a good starting point for choosing the right cover size, we also recommend cross-checking the actual fabric length and width required to ensure you select the correct fit.

- Fabric Length - Measure along the length of your boat, over the top of any boat fittings e.g. bow rails, handrails, cabin, windscreens etc. to the point on the hull where the cover’s hem will finish.
- Fabric Width - Measure across the widest point of your boat, over the top of any boat fittings e.g. bow rails, handrails, cabin, windscreens etc.to the point on the hull where the cover’s hem will finish.
| Cover Size | Fabric Length | Fabric Width |
| 4.6-5.2m 15-17ft | 730cm | 490cm |
| 5.2-5.8m 17-19ft | 810cm | 500cm |
| 5.8-6.4m 19-21ft | 850cm | 500cm |
| 6.4-7.0m 21-23ft | 900cm | 540cm |
| 7.0-7.6m 23-25ft | 940cm | 570cm |
| 7.6-8.2m 25-27ft | 1000cm | 600cm |
| 8.2-8.8m 27-29ft | 1060cm | 650cm |
Important care & warranty notes:
Protect sharp and protruding fittings (cleats, anchors, etc.) by adding padding where the cover contacts them; damage from rubbing against sharp or raised hardware is not covered under warranty.
For long‑distance towing, use extra straps (not included) over the top and keep tension even; damage caused by improper or loose strapping during trailering is also not covered under warranty.
