Operational history

In a 2008 review in ''Sailing Magazine'', John Kretschmer wrote, "although the Com-Pac 23 is a very practical boat, its wide appeal comes from its traditional appearance. The sheerline sweeps aft from the short bowsprit before bending up again just before the transom-hung rudder. The box cabintrunk, with round or oval bronze ports, flows naturally into the deck lines. From a distance the boat looks bigger than 23 feet. There is a shallow forefoot and a long, shoal keel with a draft of just 2 feet, 3 inches. Any more draft would make it difficult to launch on many ramps." In a 2010 review Steve Henkel wrote, "the Com-Pac 23 ... is now in its fourth iteration (called Mk IV). Along the way various changes have included a bowsprit which moved the sail area center of effort forward, reducing weather helm), a small increase in ballast weight, an on-deck anchor locker, improvements in hardware including a switch from round ports to rectangular ones, a PVC rubrail with stainless steel striker plate, a foil rudder blade in place of one made of flat plate, an optional 9 hp Yanmar inboard diesel engine, and others. (The company included the new bowsprit in the boat’s length, changing it from 22' 9" to 23' 11"; we use LOD, not LOA, as a measure of length, so we exclude the bowsprit.) Best features: The finish is above average, with lots of teak below and a teak-and-holly sole, Worst features: The draft of the Com-Pac 23 at only 2' 3", with no centerboard, limits the boat's ability to sail close to the wind." In a 2012 boats.com review of the Pilothouse model, Zuzana Prochazka wrote, "'cute as a button' is one way to describe Com-Pac Yachts’ 23-foot pilothouse sloop, but the emphasis on the diminutive is misleading because the CP 23 PH is much more than just loveable and small. It’s actually an innovative and serious trailerable cruiser, enhancing Com-Pac’s reputation for building tough boats with well-thought-out details."
