RIB GRAND S420 NS
The GRAND S420 NS is a 4.2 m RIB inflatable in the Sport version: with a two-person jockey console like on a jet ski. Two people sit at the console, and when needed the boat carries up to 6. It runs with a 25–50 hp engine and weighs 145 kg.
Hull and tube
At speed the hull is what counts: the S420NS has a medium V (20° / 17°) with the DART system, hand-laid high-density GRP, a wider cockpit bow and stability in a soft ride. The three-chamber tube absorbs wave impacts and deflects spray, so it stays dry even at full power.
Deck
The CS-03 sport console has a locker for boat or sports gear, a windscreen, a grab rail and mechanical steering, and the seat is upholstered in Silvertex, resistant to sun and water. Next to the console of the S420 NS there is still plenty of room for boards or dive tanks, and water drains into a drainage well. The S420 NS has a wet bow locker, hidden wiring under the deck and a transom ready for towing inflatables and skiers.
What it is for
The S420 NS is a good choice for clubs, instructors and wakeboard fans: fast, agile and big enough to take gear and a few people.
