Design and Construction
The 435 represents a radical approach to multihull cruising, and that character is visible the moment you look at the structure. Aboard this catamaran, the battle to reduce weight is omnipresent, beginning with the epoxy resin vacuum infusion process used to manufacture the solid fiberglass hulls and deck. Lavranos left his signature in the cabin roof, whose fairly sharp angles and large picture windows distinguish the silhouette from softer-edged competitors. The fine entries of the hulls do not favour load-carrying capacity, but tend to give a hull with good performance, both in terms of pointing ability and speed. The forward part of the nacelle sits a bit lower than the aft section, yet its height above the water is clearly greater than average, so the waves can’t hit it too often in choppy seas. Writing in Multihulls World, reviewers judged the finish of a very high level, an assessment consistent with a boat aimed at serious passagemaking rather than charter abuse.
Rig and Performance
The 435 carries a carbon mast on a fractional sloop rig, a choice that reinforces the lightweight ethos without sacrificing the sail area needed to drive 1,281 square feet of canvas. Period reviewers found her light and fast, and noted that she sails well and fast in practice rather than merely on paper. With a hull speed around 8.6 knots and a displacement-to-length ratio near 91, the platform is built to move; the fine-entry hull form rewards crew who keep her trimmed and lightly loaded. Two 29-horsepower Yanmar diesels provide auxiliary power, each backed by a 2nd alternator and 2 smart regulators for robust electrical recovery at anchor or under way.
Accommodations
Below, the 435 is laid out for liveaboard comfort rather than maximum berth count. She has two huge state rooms supplemented by two single cabins, with heating in each hull for cold-weather cruising. The saloon is panoramic, wrapping the crew in light and visibility, while the chart table is complete and offers a real work space for passage planning. Multihulls World described the boat as comfortable, and the combination of private staterooms, single cabins, and a proper navigation station supports extended offshore use. The full Ocean Crossing Pack and two AIR Breeze wind generators on the stern round out a specification clearly oriented toward self-sufficient voyaging.
Refits and Ownership
One documented 435 was being renovated at the time of its listing and was to be ready beginning 2015. The scope of that refit illustrates the kind of mid-life work these boats see: she was being spray painted completely including mast, receiving new ropes, a new stainless-steel davit, a new lazy bag and bimini, and a new wind generator. For an owner, such a program shows the structure taking paint and hardware upgrades well, and the modular deck equipment is straightforward to renew.
The Verdict
The FastCat 435 is a purpose-built ocean cruising catamaran that trades payload for pace and polish. Lavranos’ fine-entry hulls and carbon rig deliver the light, fast behaviour Multihulls World praised, while the high-level finish and panoramic saloon make her a genuine home afloat. The radical weight discipline is her defining trait — and her one real compromise.
Pros
