Dehler 25 Sailboat Review, Specs, and Listings

Design and Construction

The hull is single-skin fiberglass polyester with wood trim, while the deck is built in a balsa and fiberglass polyester sandwich. This construction keeps weight down while adding stiffness overhead. The hull has a raked stem and a gated, walk-through reverse transom—details that suit the boat’s ramp-launching purpose rather than pure coastal cruising.

Van de Stadt’s hull measures 24.77 feet overall, with a 21.83-foot waterline, an 8.27-foot beam, and a displacement of 3,245 pounds. Period assessments describe the Dehler 25 as very well made, nicely finished, and cleverly laid out for easy launching and retrieval at a ramp.

Rig, Keel, and Handling

The Dehler 25 carries a 7/8 fractional sloop rig with aluminum spars, wire standing rigging, and a deck-stepped mast supported by a single set of swept spreaders. Upwind sail area is 336 square feet. Downwind sail area is 530 square feet, including the optional 360-square-foot spinnaker.

Buyers could choose a lifting keel with a stub or a fixed fin. The lifting keel draws 4.50 feet when extended and 1.30 feet when retracted; the fixed keel draws 4.33 feet. The swing-keel model carries 827 pounds of fixed lead ballast and another 827 pounds of flooding water ballast, which drains for road transport. Testers noted that this water-ballasted arrangement, with an equal amount of lead, produces a 51% ballast ratio. They found the boat suitably stiff, unlike some other water-ballasted designs.

The heavy lifting keel is raised by inserting a standard winch handle into a deck socket forward of the mast, which operates a worm gear. A tiller controls the internally mounted spade rudder, and the rudder is easily removable.

Well-designed mast-lowering gear adds to the boat’s trailerability. A supplied road trailer with a four-wheel floating slipway trolley completed the trailerable package.

Accommodations

The Dehler 25 sleeps four. The bow cabin has a double V-berth with the head tucked beneath it, while two straight settees in the main cabin serve as quarter berths. Just aft of the bow cabin, the galley is to starboard and includes a two-burner stove and sink. The navigation station faces it across the cabin.

Headroom is 57 inches—4 feet 9 inches by testers’ measurements—which can make stays longer than a few days a test of will. A canvas dodger may reduce the sense of confinement.

Tankage is modest, with 10 gallons of fuel and 19 gallons of fresh water. Those capacities are consistent with ramp-launched weekend sailing rather than extended cruising.

Trailerability and Ownership

Dehler offered the boat either factory-finished or as the Dehlya 25 kit. It was available in various build stages for amateur completion using factory subassemblies.

The automatic water-ballast system and removable rudder simplify trailering. The reverse transom also carries a sliding outboard mount, which runs on tracks so the engine can be raised and lowered easily. It’s a practical feature worth preserving.

Owners of lifting-keel boats should keep the worm-gear keel mechanism serviced. For comfort, a dodger is the most useful refit.

Known Issues

The principal limitation is cabin height. The 4-foot-9-inch headroom is the boat’s one repeatedly cited drawback: tolerable for short trips, but cramped during longer stays.

The Verdict

The Dehler 25 is a clever, well-built small cruiser that makes the most of its length through smart ballast engineering and genuine trailerability. It suits sailors who want a van de Stadt-designed hull, have a modest budget and a driveway, and can accept limited living space.

Pros

High 51% ballast ratio from combined lead and water ballast keeps the boat stiff
Genuine trailerability, with draining water ballast, a removable rudder, and mast-lowering gear
Walk-through reverse transom and sliding outboard mount help with ramp launching
Fractional sloop rig and a sensible 336-square-foot upwind sail plan
