Catalina 42 mk1 — Specs & Cruising Analysis
Alexandra
The Catalina 42 mk1 requires a marina slip roughly suited for a LOA of 41'10" and a minimum berth beam allowance of about 14 ft; air-draft clearance near 53 ft must be checked for fixed bridges. Its 20,500 lb displacement mandates travel-lift or crane equipment rated for at least 11 tonnes for haul-out and transport, while the wing keel option (4'10") improves access to shallow harbors and sheltered anchorages, reducing berth restrictions common to deep-draft marinas.
Design and Construction: Practical Implications for Owners and Charter Operators
Built between 1988 and 1991, the Catalina 42 mk1 pairs a Nelson/Marek hull form with Catalina Yachts production methods. The hull is primarily GRP below the waterline with a balsa-cored deck, producing a stiff structure that balances durability and weight. For operators and renters, the widespread availability of spare parts and the commonality of systems on production Catalina models make maintenance logistics straightforward compared to bespoke yachts.
The design’s massive aft beam translates into generous interior volume and a spacious cockpit, a clear benefit for charters: more passenger space at anchor, easier provisioning, and simplified deck work. Two main keel choices—deep fin and wing—allow owners to prioritize performance or shallow-water access depending on their cruising ground and the marina infrastructure they plan to frequent.

Performance Ratios: What They Mean for Cruising
| Ratio Type | Value | Interpretation |
|---|---|---|
| SA/D | 17.1 | Moderate sail power—good in light air without being over-canvassed. |
| D/L | 196 | Light-to-moderate displacement—capable of lively speeds and surfing down waves. |
| B/D | 40.5% | High ballast fraction—strong stiffness and confidence in gusty conditions. |
| CSF | 1.97 | Below 2.0—favourable capsize screening for coastal offshore work. |
| Comfort Ratio | 25.4 | Quicker motion than heavy bluewater types but comfortable for coastal passages. |
On-Water Behavior
The Catalina 42 mk1 excels off the wind and when surfing reaches, aided by its broad stern and moderate displacement. Upwind tracking improves noticeably with the deep fin keel, while the wing-keel version rewards owners cruising near shoals and in Mediterranean or Gulf marinas. The combination of a large cockpit and reachable primary winches suits charter operations and family sailing where ease of handling is a priority.
Cruising Accommodation, Tankage and Practicalities
Layout options—either a three-cabin family arrangement or a two-cabin owner version with a pullman berth—make this model flexible for rental fleets or private owners. The galley’s wrap-around configuration and significant refrigeration capacity facilitate extended coastal cruises. Tankage of approximately 115 gallons (435 litres) of water and 46 gallons (174 litres) of fuel frames typical provisioning and range: suitable for multi-day coastal trips but requiring planning for longer offshore legs.
- Pros: Spacious interior, stable platform, simple rig for short-handed sailing, flexible layouts.
- Cons: Not a heavy-sea bluewater tank, lighter hull schedule than hand-laid custom yachts, forward passage in owner’s layout can be narrow.
Structurally, Catalina used a grid to distribute mast and keel loads—this eases surveys and repairs, and helps keep long-term upkeep predictable for charter managers and private owners alike. The production volume of this model also supports resale value and parts availability in the used market.
