The S370N and S420N represent a new generation of mid-size RIBs from GRAND.
Both models are based on the DART hull system with the following key features:

  • Exceptional stability with softer ride and improved performance
  • Impressive cockpit with wider bow section, more seating and storage
  • Extremely lightweight hull made of hand-laid high density GRP
    Competitively priced for great value!

  • The BASE version (S370N, S420N) — boat with 2 wooden seats and oars
  • The SPORT version (S370NS, S420NS) — with (CS-01) SPORT console for the S370N, and a new (CS-03) console for the S420N
  • The DELUXE version (S370NL, S420NL) — with a new (CL-11) DELUXE steering console and rear (SD-06) double seat with soft back and securable locker.
