The new Lagoon 35CCC is designed by Morrelli and Melvin from Newport Beach, Calif. It is the first American-designed cat in the line and a credit to Morrelli and Melvin.

If you are a multihull fan, try not to be too thin-skinned as you read this review. I will remind you once again as we start with the sailplan that cats do not show their best side in profile. Your eye simply cannot accommodate the impact of the beam when all the profile lines are pulled into two dimensions, so the boat looks boxy and too high. In the water this height will come down, and the apparent house bulk will shrink. I'm not sure this design would ever look low and sleek like the bigger Lagoons, but that's also a characteristic typical of monohulls.

The biggest items controlling the design of cruising cats are weights, displacement, beam, and clearance between the bridgedeck or underwing and the water. It interests me that M&M lists the displacement of this cat as 9,500 pounds empty and 13,880 pounds with a full load. That's an increase of 4,380 pounds. Having this figure firmly identified is crucial in cat design, as it effects the clearance between the bridgedeck and the water. The small footprint or waterplane area of cats means that they have a low pounds-per-inch immersion factor. The Lagoon 35CCC light has 25 inches of clearance but only 18 inches when loaded. This means that waves may slap and bang on the surface between the hulls.

The designers list this boat as a coastal cruising cat rather than an offshore cat. Of course you could raise the clearance by just pushing up the profile of the boat, but the profile is already high and raising it could not reasonably take another 12 inches of the height. This factor is difficult to quantify and must be balanced by a talented design team. The D/L of the Lagoon — loaded — is 169.

The layout features accommodations for two couples in staterooms located in the stern of each hull. The galley is up in the main cabin. You can squeeze galleys into the hulls, but they do not work well there due to the restricted useable beam in the hulls. Note the large volume dedicated to forecastle stowage.

The rig is a straight sloop. The traveler locates nicely on the aft end of the bridgedeck where it can span almost the entire beam of the cat. The great beam of the cat allows the shrouds to be led to the edges of the hull. Short diamond stay spreaders support the lower spar panel. If we use the area of the genoa in our total sail area calculations, we come up with an SA/D of 17.18. The cockpit area is where cats really shine.

Tillotson-Pearson is building this new cat. The hulls and deck will be balsa-cored. There are twin Yanmar diesels in the hulls and tankage for 68 gallons of water, 38 gallons of fuel and 30 gallons of holding. Morrelli and Melvin have made cats their specialty. I look forward to seeing this new Jeanneau North America product in the water.
