The Silver Line S520 is one of the latest mid-size designs from GRAND, which from its inception has become a most popular family and holiday boat.
The key points within the design philosophy were to produce a practical, spacious, easy transportable and well-equipped boat at a highly competitive price. The Deep “V” hull ensures the boat copes easily with choppy inland and coastal waters. If you are looking for a safe, reliable, roomy and easy transportable RIB for your family holiday, look no further – the S520 is exactly what you need!
The S520 is available in three versions:
- The BASE version (S520) — boat with bare cockpit suitable for customization
- The SPORT version (S520S) — boat with (CS-03) SPORT console with windshield, handrail and steering system
- The DELUXE version (S520L) — boat which includes the new (CL-12) DELUXE steering console with windshield, handrail, front seat and seatback with stowage compartment plus a rear (SD-02) double seat with stainless steel rails, soft back with lockable stowage compartment.
Each model is available with PVC or HYPALON buoyancy tubes.
