Cockpit

Your people.
Your best days.

Wide enough for 14 guests out on the water. Intimate enough for two at anchor. The 370 GTX cockpit adapts to whatever the day calls for — sun lounge, dining table, or simply the best seat you've ever had. A stern bar built for evenings that stretch long past sunset.

Our promise to you

Own it with
confidence.
For a decade.

Every 370 GTX comes with the only 10-year structural warranty in its class. Not a sales tactic — a reflection of how the boat is made. It means one thing for you: get on the water without a second thought. Take your family out without hesitation. Be proud of this boat in ten years, the same way you are today.

01
Complete peace of mind on the water
You bought a boat to enjoy it — not to worry about it. The 10-year structural warranty means you can focus entirely on the experience.
02
Confidence that lasts as long as you own it
A warranty this long is only possible when a boat is built properly from the start. It's the reason your 370 GTX will still feel solid a decade from now.
03
Resale value that holds
A transferable 10-year structural warranty makes a boat easier to sell and worth more when you do. It's the difference between a purchase and an investment.

Year warranty — only in its class
