Aluminium vs Fibreglass RIB Hull Comparison
| Aluminium | Fibreglass | |
|---|---|---|
| Weight for length | Lighter — often 15–30% less | Heavier |
| Ride in chop | Firmer, noisier | Softer, quieter |
| Beach and rock landings | Very tolerant | Gouges gelcoat |
| Finish | Functional | Superior |
| Repair | Weldable | Glass and fair |
| Typical use | Davit tenders, clubs, workboats | Motor yacht tenders, dayboats |
How to Choose a RIB Hull Material
