Its American-built character is plain to see: warm, traditional joinery below, a practical deck plan, and measured advances in rig and keel engineering rather than a clean-sheet reinvention.
Design and Construction
The 356’s hull and deck are carried over from the 355, but the laminate beneath the gelcoat is thoroughly modern. Multiaxial fiberglass forms a stronger, stiffer structure, with carbon fiber used in select locations and assemblies create a stronger, stiffer structure without a weight penalty. A full structural grid and hull liner are bonded to the fiberglass hull, while a vinylester resin barrier coat resists osmotic blistering. Catalina backs the boat with a five-year gelcoat blister-protection warranty and a five-year hull-structure warranty.
The deck is a sandwich-cored fiberglass panel with a bonded, full-fiberglass headliner. Its surfaces have a molded-in diamond-pattern non-skid. Below the waterline, a watertight collision bulkhead with a strike zone adds a measure of security rarely detailed in this class.
Two keel options give the boat different cruising capabilities. The custom Catalina/Mars shoal-draft lead keel has a cruising-bulb, low-drag form that lowers the center of gravity and, according to the builder’s engineering, reduces wetted surface by 22 percent compared with earlier shapes. This version carries 6,200 pounds of ballast and draws 4 feet 6 inches.
A standard deeper fin keel remains available for sailors who favor ultimate windward bite over shallow gunkholing. It has 5,200 pounds of lead ballast and 316 stainless steel bolts and draws 6 feet 8 inches.
At half load, displacement is 16,800 pounds. The waterline is 30 feet 2 inches, and beam is 12 feet.
Rig and Handling
A new deck-stepped Seldén rig lies at the heart of the 356’s sailing profile. LMP mast sections reduce weight aloft by 20 percent, while swept-back double spreaders allow closer sheeting angles. All shrouds lead to a single inboard attachment point near the cabintop, leaving the side decks completely clear for moving forward.
The twin mainsheet system uses a modified German-sheeted arrangement. It eliminates a traveler and allows the crew to trim from either side of the cabintop. The standard sail inventory includes a furling mainsail with vertical battens and a 135 percent genoa with UV protection. A Doyle code sail complements the rig off the wind.
Under sail, the 356 behaves like a settled cruiser rather than a racer. In about 12 knots of true wind at 115 to 120 degrees apparent, she made an easy 5.1 knots. Tightening to 90 degrees produced 6.3 knots, while in 15 knots true at 45 degrees she held 6.2 knots. The helm felt balanced, if a little stiff, and the boat never felt edgy or pressed as the wind built. She also proved responsive and quick through a clearing tack.
Under power, the 30-hp Yanmar 3YM30AE and fixed three-blade propeller delivered 6.6 knots near 2,800 to 3,000 rpm. At wide-open throttle, the boat reached 7.1 knots.
Cockpit and Deck
The 356 keeps the 355’s cockpit layout. A solid stainless steel railing encircles the cockpit as far as the side-deck gates, while contoured coamings provide protection around the seating area. A walk-through stern leads to the sugar scoop and helm seat. Matching stern cockpit seats and a telescopic boarding ladder help make movement around the deck safe and easy.
Accommodations
Below, fresh fixed ports in the hull sides and new opening ports along the cabin trunk bring in more light and give the interior a more contemporary look. Catalina’s varnished teak-and-maple finish, solid teak trim, and teak-veneer bulkheads retain a warm, traditional character that sets the boat apart from minimalist European styling.
Inner-spring mattresses are fitted in the fore and aft berths. Cedar-lined hanging lockers, fabric-covered cushions, and a textured teak-and-holly sole complete the practical cruising interior. A chart table with storage serves the navigator.
The galley gains solid Corian countertops, a polished stainless steel double sink, a two-burner LPG stove with oven, and DC refrigeration with freezer access from the front and top. In the head, the sink changes to a popular vessel style.
Systems and Equipment
As a 6 Series model, the 356 incorporates more than 20 modifications over the 355, many of them mechanical and electrical. These include a larger Group 31 starting battery, new LED lighting, and USB outlets throughout. The Sensar Marine Boat Monitor is standard, and optional diesel heating can extend the sailing season.
The standard equipment list is extensive. It includes an electric anchor windlass; a Raymarine or Garmin multifunction display with transducer; an electric macerating head with holding tank; and a high-water bilge alarm with Sensar monitoring. From new, the builder’s five-year structural and blister warranties apply.
Known Issues
Period testing identified two handling details that deserve a buyer’s attention. The genoa’s furling line had no clutch or jammer, leaving it unsecured at the cockpit.
More significantly, the twin mainsheet blocks ahead of the dodger can’t be reached from the helm. Without crew support, that could make mainsail trimming difficult for a singlehander in a breeze. Neither issue is structural, but both matter when planning to sail short-handed.
The Verdict
The Catalina 356 is a thoughtfully evolved cruiser. Rather than starting again with a clean-sheet design, Catalina has wrapped a proven hull in smarter rig, keel, and systems engineering. The boat sails predictably, offers traditional accommodations, and comes with the monitoring and comfort equipment a modern couple or small family expects.
For short-handed sailors, the mainsheet and genoa-furling ergonomics are the only real caveats.
Pros
- Proven 355 hull and deck with modern multiaxial and carbon-fiber reinforcement, plus blister protection
- New cruising-bulb keel lowers the center of gravity and reduces wetted surface by 22 percent
- Deck-stepped Seldén rig cuts weight aloft by 20 percent and leaves the side decks clear
- Warm, traditional interior with new ports, Corian surfaces, and inner-spring berths
- Extensive standard equipment, including a Sensar monitor, windlass, and multifunction display
Cons
- Twin mainsheet can’t be trimmed from the helm, complicating singlehanded sailing
- Genoa furling line lacked a clutch or jammer on the test boat
