Catana 70 Buyer's Guide
Shopping the brokerage market for a used Catana 70 means looking at a 68-foot French semi-custom catamaran designed by Marc Lombard and built by Catana SA, the first in its series and also badged as the Arcadia 70. These are large, carbon-reinforced cruising multihulls with daggerboards and a stated aim of joining athletic performance to a luxuriously appointed interior, so the used buyer is weighing a serious passage boat rather than a dock-side condo.
Layouts on the Used Market
The Catana 70 was offered with three or four double cabins, and because it is a semi-custom design, individual hulls may differ in how that accommodation is finished and divided. The 31-foot beam and 68-foot length give genuine volume, and the spec record shows a drivetrain of 2 x 150 horsepower with a 2,000-liter fuel tank and two 400-liter water tanks, so regardless of cabin count the boat supports long independent cruising.
Equipment and Common Upgrades
For a buyer, the consequential equipment centers on power and energy: the twin 150 hp diesel engines provide redundancy and thrust, while the large fuel and water tanks define range. Sail-handling hardware clusters around the port-side station with carefully led reefing lines, mainsheet, and topping lift, and the rig itself carries a 100-foot-plus headsail of just over 1,000 square feet plus a 2,150-square-foot kite for offwind sailing — any used boat should be checked for gennaker condition and furling gear. Beyond that, the interior sycamore-laminated sandwich panels are a defining comfort feature rather than a simple upgrade.
What to Inspect
The known construction detail to verify is the sycamore-laminated sandwich panel work, where glass or carbon cores were used depending on location anchor. On a semi-custom hull, confirm that the specified location-based material split is present and that the laminate shows no delamination at panel edges. The sail-handling leads were designed for clarity, so inspect the port station for chafe or re-routing that defeats that intent anchor.
Availability and Buyer's Takeaway
For the buyer, the short checklist is: confirm hull number and semi-custom spec variance, verify twin-engine hours and tank integrity, inspect the location-specific glass/carbon sandwich panels, and assess the large gennaker and port-side sail-handling system for wear.
