Welcome to RH yachts

FROM THE VERY BEGINNING our goal at GCG MARINE INC., has been to design, engineer, and manufacture a very high quality stylish LOBSTER motor yacht. Built using only the finest quality materials and state of the art techniques, we wanted to make it possible to offer you a unique opportunity to get involved in tailoring your own yacht to your specific needs. Experience a genuine sense of partnership that’s unique in this industry.

Owners are enthusiastically encouraged to become involved with our design team to conceive just the right personalized interior layout. Wherever possible, sustainable, environmentally responsible materials are offered. Nothing is compromised to deliver the best owner experience. From the very beginning of the construction, through commissioning and delivery, and continuing for many years of owner enjoyment – you will remain as part of the process all the way. Careful attention is taken to help you in the selection of just the right woods, fabrics, flooring, lighting and counter surfaces and other interior refinements. All leading brand names are gourmet appliance options to make your galley and salon a unique, functional, center for entertaining. Rockharbour yachts usually come standard with full amenities. Combining the best use of interior space without crowding is top priority of our interior design criteria. You won’t find low ceilings, narrow, steep staircases.Moving about the boat, at anchor or underway, is an easy, comfortable and pleasant experience.
You dream it ...we will make it...

It’s a “green” process. GCG Marine, employs the resin infusion process, using 100% vinyl ester resins and Core Cell® coring material in the construction of the hull and superstructure. This produces the strongest and most durable structure of any fiberglass vessel made today. Vinyl ester resins protect against osmotic blistering and due to the elasticity of the fiberglass, reduce the chances of crazing or spider cracking. Another advantage of this process is virtually no VOCs are released into the atmosphere during the infusion process.
