Delphia 40.3 Sailboat Review, Specs, and Listings

Design and Construction

Delphia built the 40.3 to Germanischer Lloyd’s quality standards. The hull is conventionally hand laid, with solid polyester laminate below the waterline; the topsides and deck are cored with Airex foam for lightness. Around the keel, the laminate is twice as thick—a sensible reinforcement in this high-load area.

The deck’s molded non-slip provides grip whether wet or dry. Slightly angled side decks are easier to negotiate when the boat is heeled, while chainplates and genoa tracks are tucked well inboard to leave an unobstructed passage. Teak inlays on the cockpit seats and sole lend a classy air. The helm seat drops down neatly to open a walkway aft to the boarding platform.

Shallow underwater sections, moderate beam, and a generous waterline are paired with a deep spade rudder. The standard deep fin keel has a bulb and draws 7ft 5in. The deep-keel model that reviewers sailed provided noticeable extra “bite” on the water and kept the ballast low for maximum stiffness. Buyers could also choose a shoal keel drawing 5ft 10in or a swing-keel version, which draws 3ft 3in with the keel up and 6ft 4in with it down and has twin rudders.

Rig, Sailing Performance, and Handling

The 40.3 carries a 7/8ths fractional rig. This keeps the headsail manageable and allows the backstay to flatten the mainsail when beating. The standard full-battened main holds a good shape and is easy to handle with the optional lazy jacks and zip bag, although one tester disliked having the mainsheet on a coachroof winch when sailing singlehanded.

Most control lines run through clutches to a pair of Lewmar 30ST winches on the coachroof. The genoa sheets lead to 48ST primary winches on the coamings beside the helm.

Under sail, the boat tracks well off the wind with little or no rudder adjustment. The Jefa rod steering feels positive but very light. Testers also found her quick for her size. Hard to windward, she made 5.4 knots in 12 knots of apparent wind, increasing to 6.2 knots on a close reach. At that point she was balanced enough for the helm to be left alone. The 40.3 also tacked briskly, even in light air, and accelerated back to speed within seconds.

Her most efficient point of sail is just over 40 degrees off the wind. Hard on the wind, she’ll sail at about 28 degrees to the apparent wind.

Interior and Accommodation

Buyers could order the 40.3 with two, three, or four cabins, spread across six arrangement plans. The raised-saloon coachroof follows the modern trend, with large windows and hatches that keep the interior bright. Headroom is a generous 6ft 6in, and six people can eat at the saloon table without feeling cramped. The joinery gives the saloon a pleasantly woody character without making it gloomy. Both heads are fully molded, hose-down compartments with good headroom.

The three- and four-cabin models have a conventional dinette and linear galley, an arrangement popular on charter yachts. The two-cabin version gains a larger U-shaped galley, which offers more security at sea, as well as an even larger aft berth with its own ensuite head and shower.

The three-cabin test boat had an ensuite owner’s cabin forward, with a generous V-berth and dressing area. Its aft cabins also had spacious berths. In the four-cabin version, a twin-bunk crew cabin replaces the forward head, which moves to the opposite side.

The forward-facing chart table is a little small. Its hinged console provides space for instruments, but there’s no bookshelf.

Ventilation and Handholds

Assessments of the ventilation conflict. One review noted a lack of ventilation openings, while another praised the excellent ventilation provided by the large skylights and numerous hatches.

There are handholds in the raised saloon, but none forward of the mast—a point worth noting when moving below on an offshore passage.

Engine, Systems, and Options

The standard engine is a 53hp Volvo D2-55 diesel with sail drive. It’s quiet, produces minimal vibration through the cockpit sole, and drives the boat at a comfortable 6 knots at 1,800 rpm, with a top speed of 7.5 knots.

An optional bow thruster makes close-quarters handling trivial. The deep anchor well contains the windlass, leaving nothing protruding that might catch a crewmember. Other options include a full cockpit tent to extend the season, lazy jacks, and twin wheels.

For easier fault-finding, the hinged electrical panel carries gauges. The battery bank consists of one 110AH engine battery and two 110AH house batteries.

The Verdict

The Delphia 40.3 is a thoughtfully engineered Polish cruiser with genuine layout flexibility, a stiff and well-balanced hull, and a finished interior that punches above its production status. She’s quick on the wind, manageable short-handed with the right options, and well suited to extended cruising.
