  • Catamarans are incredibly safe and easy to sail and power.
  • Lagoon is the largest maker of Cruising Catamarans in the world

Manufacturer Provided Description

Balance in design is the keyword: – Balance between volume and performance, – Saloon and cockpit, – Cabins and washrooms, – Accommodation and deck spaces. Also the harmony of soft lines reminiscent of the Lagoon 410’s simplicity and inspired by the Lagoon 620’s charm and elegance.

Additional Description
The accommodation’s strong points:

  • Optimal practicality.
  • Maximum light in saloon and cabins.
  • Ventilation adapted to each area of the boat.
  • More stowage spaces in owner’s cabin.
  • Saloon design inspired by the success of the Lagoons 420 and 440 where the galley is between the salon and the cockpit.
  • Unusual concept in the forward cabin(s) where the double bed can be converted into twin beds.
  • Shower curtain in the washrooms.

Additional Description
The deck space, its strong points:

  • Hard top bimini in line with the cabin top for a better protection from the sun (streamlined, more aesthetic).
  • Easier to move around the stern, offering more shelter.
  • Easier access to the dinghy via the transoms
  • Flush deck hatches.
  • Moving around more safely (no step exceeds 220 mm).
  • Open cockpit for socializing.

I had a very good experience with Will Miller at TMC. He is very knowledgeable about his business and took care of all aspects of my purchase, and where he couldn’t places me in touch with the people who could. The transaction went very smoothly as far as I was concerned.

Your team delivered on every mark. You’ve got an amazing broker in Mark Wattrus and I’m confident you will have continued success moving forward together. He was available 24/7 whenever I had questions. We had a great initial visit on the boat and his marketing plan and photos were superb

I couldn’t be more grateful to have had TMC on my side throughout this process. Buying was a new experience for me and I know it wasn’t the easiest deal you’ve ever had, but you were competent and kind throughout.
