Design and Construction
The Mk II is built around a hand-laid fibreglass hull with a deck cored in balsa for stiffness and insulation, though solid fiberglass is retained in the high-stress zones where deck hardware mounts. This is a practical cruising structure rather than a blue-water fortress: the boat is not built to the standards of heavier, dedicated blue water yachts, and the keel-hull joint and deck fittings demand survey attention for any sign of water intrusion or stress. The Mk II also received a redesigned deck over the original, and underneath it carried the standard fin keel with bulb and spade rudder, or a shallower wing keel option for reduced draft.
Rig and Handling
Where the original 400 used a single wheel and smaller cockpit, the Mk II introduced a larger cockpit with twin helm wheels and a walk-through transom to a swim platform, letting the helmsman pick the windward side for clearer sightlines to sails and water. The rig was also changed: a taller mast with slightly swept-back spreaders delivered a marginal performance boost and a reworked sail plan, while the masthead configuration—forestay near the masthead—keeps things robust and simple, readily flying a 135% genoa on a roller furler. All primary control lines lead aft to the cockpit, so a single or double-handed crew can manage the boat without leaving the helm. With a 100% foretriangle of 408 square feet and a 400-square-foot mainsail, the sail area is generous for the hull’s moderate-to-light displacement.
Accommodations
Both two- and three-cabin layouts were offered, but the two-cabin version stands out for a very large aft master suite with a queen berth and two heads, a layout that trades some cockpit locker storage for private volume. The Mk II generally presents a more open-plan saloon and an updated galley with more storage than the original, and the compromise of limited external locker space is the liveaboard’s known trade for that big aft cabin. The walk-through transom and twin wheels also ease stern access, blurring the line between interior comfort and cockpit practicality.
Keel Options and Performance
The deep fin keel gives the better stability and upwind performance, while the wing keel buys shallower draft at the cost of a slight reduction in stability and upwind performance. Design ratios place the boat as a moderate-to-light displacement cruiser, and a Capsize Screening Formula of 2.00 sits in the acceptable range for ocean work. Taken together, the Mk II reads as a highly capable coastal and moderate offshore cruiser rather than a stripped expedition vessel.
Known Issues and Ownership Notes
The documented watch-list is narrow but specific: areas around deck fittings and the keel-hull joint should be surveyed for water intrusion or stress, the sort of detail a thorough pre-purchase inspection is built to catch. Otherwise the boat’s construction choices—balsa-cored deck with solid patches under loads, hand-laid hull—are conventional cruising practice for the era and contribute to a straightforward ownership profile.
The Verdict
The Catalina 400 Mk II is a measured evolution: twin helms, a walk-through transom, a taller rig, and a more open interior turned a competent 1990s cruiser into a comfortable 2000s one. It is not a heavy offshore specialist, but its numbers and layout make it a sensible coastal and moderate offshore candidate.
Pros
- Twin helm stations with walk-through transom and swim platform for easy stern access
- Taller mast with swept-back spreaders for a marginal performance gain
- Two-cabin layout with very large aft master suite and two heads
- Masthead rig flies large headsails easily on roller furler; all controls led aft
- Capsize screening of 2.00 acceptable for ocean work
Cons
- Not built to heavier dedicated blue-water yacht standards
- Wing keel trades stability and upwind performance for draft
- Large aft cabin reduces external locker storage
- Deck fittings and keel-hull joint need survey for water intrusion or stress
