Design and Construction
The Montgomery 17 reads as a purposeful pocket cruiser rather than a scaled-down racer. Its short overhangs, spoon bow, fine entry, and simulated lapstrake topsides give it balanced proportions that reflect a beautifully functional aesthetic. The solid fiberglass hull is stiffened by those difficult-to-mold strakes, which double as miniature spray rails — a clever marriage of structure and sea-keeping in a 17-foot hull. To keep cabin and deck weight down, end-grain balsa core was specified, a choice that later owners would watch carefully. The keel-centerboard arrangement uses a keel-contained pendant and full-length bearing for the board, and both ferrous and later fiberglass centerboard versions were shaped for maximum lift. A deep but slender, vertically retractable wooden rudder completes the underbody. In the tested example, glasswork was excellent, with only minor gelcoat crazing at corners and stressed fittings, and owners broadly reported solid builds with no oil-canning or delamination.
Rig and Handling
The boat carries a masthead Marconi sloop rig supported by six shrouds, a headstay, and a backstay, with 154 square feet of sail on a 100% foretriangle and a sail-area-to-displacement ratio of 18.4. The standard rig clears a bridge at 25 feet 6 inches, though a few boats were built with a 21-inch taller mast. Owners describe the M17 as solid, stiff, stable, predictable, and fast as wind builds, with weather helm that is not excessive and a tendency to "shoulder in" until overpowered, then round up safely. Like most masthead sloops, she needs the right headsail to make good progress to weather, but with decent sails points well for a shoal-draft mini-cruiser. All owners said she was easy to heave-to and reef, most tying in the first reef around 15 knots, and a few sailed her in 30-knot winds feeling the boat could take far more than the crew. With an average PHRF of 294 and a hull speed of 5.3 knots, several owners reckoned her the fastest cruising boat of her size apart from the newer Montgomery-designed Sage 17.
Accommodations
Below, the original layout placed a V-berth split by the mast post — 6 feet 7 inches long on centerline, 5 feet 11 inches wide at the head, 6 inches at the foot, with 29 inches of headroom under the trunk. A very narrow starboard quarter berth and a tiny port galley rounded out the plan, with the head tucked under the starboard V-berth section. In 1978 a revised interior replaced the galley with a full-length port quarter berth/settee, and in 1987 that berth was shortened to 5 feet to gain a larger cockpit locker. The starboard settee berth runs 6 feet 6 inches, tapering from 15 to 19 inches wide, with 36 inches of headroom. Cabin headroom is 4 feet 3½ inches; the sliding companionway is a generous 32 inches wide but travels only 10 inches before meeting the mast step. The self-bailing cockpit is deep with high backrests, 5 feet 3 inches wide forward and 4 feet 1 inch aft, seats 6 feet 7 inches long, and two drained seat hatches secure for sea, with a wet locker added aft in 1981 improving drainage.
Known Issues
The vulnerabilities that matter on a used M17 are concentrated in the keel and core. A few owners reported the usual portlight leaks, balsa core saturation, and gelcoat fading of vintage fiberglass. More common and serious were rusting cast-iron centerboards in older boats and consequent binding inside the keel; most affected owners pulled the boards, sandblasted, faired, and epoxied them. Even graver is the rust expansion of the iron or steel ballast sealed inside the keel, which makes the keel bulge and lock the centerboard in place — correction demands extensive fiberglass surgery to remove the iron or steel and replace it with lead, reshaping and re-glassing the keel.
Refits and Ownership
Trailerability defines ownership: the test boat and trailer measured 22 feet 6 inches overall, stowed mast 8 feet 6 inches above the road at the bow pulpit and 9 feet 8 inches at the stern on the factory carrier. Most owners run a long-shaft 4- or 5-horsepower four-stroke outboard, and later boats gained a retractable mount. The 1987 upgrades — lighter fiberglass centerboard with lead core, lead encapsulated ballast, and total ballast raised from 550 to 600 pounds — addressed the rusting issues at source and are worth seeking. Teak replaced perforated-aluminum toerails in 1984.
The Verdict
The Montgomery 17 is a thoughtfully detailed pocket cruiser whose Lyle Hess lines and keel-centerboard pragmatism have kept her in continuous production for decades. She rewards a careful buyer who understands her ferrous-ballast and balsa-core weak points but delivers stiffness, seaworthiness, and trailering ease that punch well above 17 feet.
Pros
- Stiff, stable, and fast for a shoal-draft mini-cruiser with easy reefing and heaving-to
- Easily trailerable keel-centerboard layout with 21-inch retracted draft
- Excellent glasswork and sturdy rigging per owners and testers
- Continuous production and strong owner community support
Cons
- Encapsulated ferrous ballast can rust, swell keel, and seize centerboard
- Balsa core saturation and portlight leaks on vintage examples
- Companionway hatch travels only 10 inches before mast step
- Early cast-iron centerboards prone to rust binding without refit
