The Com-Pac Horizon Day Cat 20 represents a sophisticated evolution of the classic American catboat, merging the timeless lines of a Cape Cod traditionalist with modern manufacturing and rigging technology. As a staple of the Com-Pac Yachts fleet, this vessel is specifically engineered for sailors who desire the expansive social space of a much larger boat within a manageable 20-foot frame. Built on the same high-performance hull as its cruising sibling, the Horizon Cat, the Day Cat prioritizes an oversized cockpit—stretching over 10 feet in length—making it one of the most capable day-sailing platforms in its class. With its signature gaff rig and a broad 8' 4" beam, the Horizon Day Cat offers a stable, forgiving, and surprisingly spirited sailing experience that appeals to both downsizing veterans and families seeking a simplified entry into the sport.

Sailing Performance & Handling
The Horizon Day Cat 20 is defined by its high initial stability and a sail-to-displacement ratio that ensures momentum even in lighter airs. According to editorial analysis from BoatUS, which evaluated the shared hull design of the Horizon series, the boat’s 2,500-pound displacement is balanced by a generous 223 square feet of sail area. This results in a vessel that remains upright and composed when modern sloops might begin to heel aggressively.
Handling is dominated by the "Mastend" system, a proprietary Hutchins design that allows the mast to be raised or lowered in minutes without the need for a secondary gin pole. On the water, the gaff-headed rig provides significant power low to the water, which reduces the tipping moment. The boat tracks well thanks to its stainless steel centerboard, which increases the draft from a shallow 2' 2" to a substantial 5' 0" when fully deployed. Owners frequently report that while she is no windward racer, her reaching performance is exceptional, and the large rudder provides authoritative control even when the wind freshens. The hull's relatively flat section aft allows it to plane under the right conditions, a rarity for boats of this traditional aesthetic.
Interior Comfort & Variations
While the "Day Cat" moniker emphasizes outdoor living, the boat does feature an enclosed cuddy cabin that adds a layer of utility missing from smaller open catboats. The interior provides two 6' 6" berths and a dedicated space for a portable head, finished with the high-quality teak trim that has become a Com-Pac hallmark. This cabin serves primarily as a dry storage area or a shaded retreat for children, though it is sufficient for an occasional overnight "pocket-cruising" expedition.
The Horizon Day Cat is the more social sibling of the Horizon Cat. While the Horizon Cat features a full-length cabin trunk and four portholes, the Day Cat utilizes that volume to extend the cockpit, allowing for a crew of six to sit comfortably without knocking knees. For those seeking even smaller iterations, Com-Pac offers the Sun Cat (17 feet) and the Picnic Cat (14 feet), both of which utilize the same gaff-rig philosophy but lack the 20-foot hull's ability to handle significant coastal chop.
Popular Mentions & Media
The Horizon series has earned a loyal following in the "small boat" community and is frequently featured in publications like Small Craft Advisor, where it is praised for its build quality and ease of trailering. The model has become a favorite for participants in coastal rallies and "raid" style events where the ability to beach the boat (thanks to the kick-up rudder and centerboard) is a tactical advantage.
Known Issues & Buyer’s Checklist
Prospective buyers should focus their inspections on the unique mechanical systems that make the Horizon Day Cat versatile.
- Mastend Hinge & Gudgeons: Inspect the stainless steel tabernacle and the hinge points of the Mastend system for stress cracks or elongated holes, which can occur if the mast is not properly supported during transport.
- Centerboard Pennant: Check the condition of the cable or line used to raise and lower the 160-pound centerboard. These are prone to wear within the trunk and should be replaced every few seasons to avoid a "board down" failure.
- Teak Maintenance: Com-Pac uses a significant amount of exterior wood (coaming caps, handrails). If left untreated, these can grey and develop cracks. Look for signs of water ingress around the handrail bolts on the cabin top.
- Rudder Bushings: Because of the high torque generated by the large catboat rudder, the bushings can wear over time, leading to a "sloppy" feel at the tiller. Ensure the kick-up mechanism is lubricated and locks securely.
Community & Resources
The primary hub for technical support is the Com-Pac Yachts Owners Association (CPYOA). This community maintains extensive archives on rigging modifications, trailer maintenance, and regional rendezvous. Because the manufacturer, The Hutchins Company, is still in operation in Clearwater, Florida, owners have the rare advantage of being able to order OEM replacement parts directly from the builder for boats that are decades old.
The Verdict
The Com-Pac Horizon Day Cat 20 is a premium day sailer that successfully bridges the gap between historical charm and modern convenience. It is an ideal choice for the sailor who wants the "big boat feel" in a package that can be kept in a driveway.
Pros
- Unmatched Stability: The wide beam and heavy centerboard make it one of the safest-feeling 20-footers on the market.
- The "Mastend" System: True single-handed mast stepping that significantly expands cruising grounds.
- Cockpit Space: More usable seating area than most 30-foot cruising yachts.
Cons
- Upwind Angles: Like most gaff-rigged catboats, it will not point as high as a modern Marconi-rigged sloop.
- Weight: At 2,500 lbs (plus trailer), it requires a vehicle with a decent towing capacity, unlike smaller rotomolded dinghies.
- Varnish Work: The classic aesthetic requires a commitment to wood maintenance to preserve the boat's value.
