Hull Design and the Water Ballast System
The defining characteristic of the Catalina 250 is its flooding water ballast system. Rather than a fixed lead keel, the boat uses a slab-like internal tank that fills with seawater to provide righting moment, then drains when the boat returns to the trailer. The ballast tank geometry exposes the fundamental limitation of this approach: the tank measures only about six inches in height on average, extending nearly fourteen feet fore and aft along the keel, and the water sits concentrated less than eighteen inches below the waterline. Compare this to the density advantage of lead — the same volume of water versus lead yields 1,200 pounds versus a theoretical 13,284 pounds — and the structural inefficiency becomes clear. The result is a boat that is noticeably tender compared to fixed-keel alternatives of similar size.
The centerboard sweeps back approximately fifteen degrees rather than dropping vertically, a detail that early factory brochures depicted incorrectly. With the board up, draft is a shoal twenty inches — genuinely useful for launch-ramp operations and shallow-water cruising. With the board down, draft extends to roughly five feet. The hull itself is solid fiberglass laminate using knitted fabric and a vinylester skin, with the deck cored in plywood for stiffness and the cabintop cored in end-grain balsa to keep weight low. The hull-deck joint uses a modified shoe-box configuration with both vertical and horizontal mating surfaces, bonded with filled polyester putty and secured with pop rivets on roughly three-inch centers — functional if not particularly elegant.
Rig and Sail Handling
The 250 carries a masthead sloop rig with the mast stepped on deck, supported by wire rigging over single spreaders with no runners or movable stays to manage. The arrangement simplifies the business of stepping and unstepping the spar at a ramp — a genuine advantage for a trailerable boat. The standard sail inventory comprises a full-battened mainsail with conventional reefing and a roller-furling 110 percent jib, a modest headsail by most standards, though the acutely swept-back chainplates positioned twenty-four inches abaft the mast prevent the boom from swinging far enough forward to make downwind sailing as efficient as it might otherwise be.
Sail quality out of the factory is described as serviceable but not high-performance, constructed of soft-lay Dacron. On a close reach, the test boat pointed within forty-five degrees and reached about five knots in the puffs. A suit of sails with flatter shape and less leech curl would add a useful increment of boat speed. The UV-treated Dacron on the roller-furling jib, supplied without sacrificial UV panels, will deteriorate in sunlight more quickly than sailcloth protected by a proper sunbrella strip.
Singlehanding the 250 is workable but imperfect: the jib sheet winches sit far forward on the cabintop, less than nine inches from the lifeline stanchions, requiring the helmsperson to abandon the tiller, move forward to the winch, handle the sheet, and return to the helm — all while the boat wanders through the tack. Moving the winches a foot or so forward on the cabintop and routing the direction of hauling to straight aft would substantially improve the arrangement.
Performance and Handling Under Sail
Cruising World's test, conducted in breezy conditions, found continuous strong weather helm that intensified in gusts, along with a tendency to oversteer during tacks and jibes. Movement along the deck fore and aft was described as compromised by narrow beam and tender behavior underway. Practical Sailor's test in lighter air painted a somewhat more charitable picture — relatively good balance given the sailplan and unusual underwater profile — though the boat needed a hand on the tiller at all times, wandering into the wind in puffs and bearing off in the lulls. Directional stability, in short, is not the 250's strong suit.
One characteristic that cuts both ways is the boat's relatively easy motion, which feels more settled than a lightweight might suggest. This quality traces directly to the spread-out water ballast acting as distributed weight in the ends — but that same weight distribution slows the boat through waves by increasing pitching inertia.
Accommodations
The interior is quite versatile for a boat this size, particularly with the companionway hatch raised for additional headroom. The layout follows a conventional plan: V-berth forward, a U-shaped circular settee around the mast compression post, an enclosed head to port with a Porta Potti, a small galley to starboard, and a large double berth aft beneath the cockpit. At four feet six inches of standing headroom — considerably less than competing designs of the era — this is a cabin where you crouch rather than stand. The extensive molded fiberglass hull liner dresses the interior cleanly and reduces maintenance, but effectively eliminates access to the outer skin for repairs or wiring runs.
The galley is honestly proportioned for its purpose: a single-burner butane stove, a five-gallon water tank that is difficult to remove for filling, and space for a portable ice chest rather than a built-in icebox. The aft berth offers generous horizontal dimensions but only seventeen inches of overhead clearance above the cushion — fine for sleeping, awkward for anything else. The forward hatch is solid fiberglass without a translucent panel, and ventilation on hot days is marginal.
Known Issues and Weak Points
Several structural and ergonomic shortcomings recur across independent evaluations. Early hulls experienced a water ballast tank leak serious enough to prompt Catalina to completely redesign the mold; the company subsequently retrofitted earlier boats, though verifying this on any given hull warrants attention. The standard fixed rudder is the deepest appendage on the boat, making it the most vulnerable to grounding damage — the optional kick-up rudder is strongly advisable and arguably should have been standard equipment from the outset. The anchor locker at the bow is sized too narrowly for many common anchor types, the stated 13-pound capacity notwithstanding. And the lack of through-hull fittings with seacocks on the galley and head drains, replaced by white plastic stubs approximately seven inches above the waterline, raises legitimate concerns about UV degradation and seawater intrusion when the boat heels.
The reefing system as originally rigged is missing a key deck block, making the single reefing line route impractical at sea. The test boat also arrived without a topping lift — an omission the owner corrected after the fact. The battery installation sits in an inaccessible position deep aft with no room to add a second battery without destroying the molded tray.
Refits and Upgrades
Later production years introduced meaningful changes. Owner comments note that the 2004 model year brought a wing keel variant and optional fixed diesel auxiliary in place of the outboard, representing a substantially different boat in sailing character. Buyers of later wing-keel examples report improved sailing qualities. For water-ballast examples, the most impactful upgrades center on reefing: adding the missing deck block for the reefing line and fitting a topping lift transforms what was an impossible offshore task into a manageable one. Moving the jib sheet winches a foot or so forward on the cabintop — or adding a longer tiller extension — improves singlehanded tacking considerably. UV protection for the roller-furling jib sail, either a sacrificial panel or a separate sock, addresses the sailcloth degradation issue. The optional kick-up rudder deserves priority on any boat that will see shallow water. Adding stanchions midway between the existing ones also improves safety when moving fore and aft on a heeled deck.
The Verdict
The Catalina 250 is best understood not as a sailing boat that happens to trail, but as a trailerable camping platform that happens to sail. Within those terms, it delivers: a large cockpit, large internal volume, and genuine ease of trailering with a medium-size vehicle. The water ballast system achieves its primary goal of allowing dry-land towing, while falling short of lead ballast in every measure that matters under sail. Workmanship sits a notch below Catalina's fixed-keel production, and the catalogue of ergonomic frustrations — winch placement, reefing arrangement, rudder vulnerability, battery access — reads like a list of things that could have been resolved at the design stage. The 2004-and-later wing keel versions represent a meaningful step up in sailing performance and are worth seeking out. For the right buyer on the right waters, the 250 earns its place; for anyone who wants a refined offshore performer, the company's own fixed-keel lineup offers better value.
