There is a distinct focus on cruising cats in the market place today. Some offered are basically twin-hulls that look like barges with sails, and I'm sure they will sail like barges, too. Others, like the new Lagoon 37, try to take a middle-road approach to proportioning the performance and comfort aspects of the design.

Look at these hulls and the space between them. The connecting bridge is well clear of the water and has a clean, sled-like shape. With multihulls we have two ways to look at the beam-to-length ratio. In the case of the Lagoon 37, designed by Van Peteghem and Lauriot Prevost, we can take the overall beam and come up with a beam-to-length ratio of 1.83; or we can look at each hull individually, ignoring the gross beam figure. This gives us a hull beam-to-length ratio for the Laguna 37 of 5.56.

A typical medium range beam-to-length ratio for a monohull would be around 3.2 to 3.5. Compare the highest monohull beam-to-length ratio we have measured, the Santa Cruz 70's 4.64, to the 5.56 of the Lagoon 37 hulls. The D/L of this design is 144. The 37 shows low-aspect-ratio fin-keels giving a max draft of 4 feet.

The Lagoon 37 appears to be a clean and refined cat with careful attention paid to styling. You certainly cannot base this appreciation on the profile of the cat alone. In profile, without any indication of the tremendous beam, almost any cat will look very high and top-heavy. But if you can view the Lagoon from about 30 degrees off the bow, the height of the house is diminished and you have a handsome, if somewhat spacey-looking, boat. The big bubble-like house grows out of a low wedge that ties the two hulls together and wraps around the stern to make the cockpit coaming.

The basic geometry of the big cat does not allow for much variation in accommodation layouts. The hulls are too narrow for anything other than berths, but they tuck in nicely and allow for a convenient break-up of sleeping spaces. The galley is in the port hull and is quite spacious. The same space in the starboard hull is devoted to lockers and the nav station. Obviously, this is an attractive charter layout for three couples. The large dinette surrounded by big windows will be a perfect place to watch the harbor.

The rig is a fractional type with a SA/D of 26. This should be enough rig to keep the Lagoon 37 moving in the light stuff when the more barge-like cats have become glued to the water. And if you want to motor, you can fire up both of the 18 horsepower Perkins diesels. The Lagoon 37 is built by Tillotson-Pearson in Rhode Island.

I am very much looking forward to an opportunity to cruise a big cat. I'm not interested in sailing a dog, but at the same time I don't want to go "camping-cruising." I want speed and comfort, too. The Lagoon 37 appears to be a clever combination of these two often contradictory design elements.
