Design and Construction
Frers drew a modern hull with a raked stem, raised transom, and a fin keel carrying external lead ballast, paired to a semibalanced spade rudder described by one reviewer as part of a thoroughly contemporary underwater profile anchor. The boat is built predominantly of fiberglass with balsa cores in both deck and hull, trimmed outside and in with teak; the interior is predominantly teak with varnished pine trim. Hinterhoeller's construction followed the builder's typical method for the design: a fiberglass hull frequently balsa-cored, with external lead ballast bolted to a reinforced sump. The first 50 hulls carried a 13-horsepower Volvo diesel saildrive, while later boats moved to a 22-horsepower Westerbeke v-drive—an ownership-era detail worth noting for any survey, since the two propulsion layouts are not interchangeable.
Rig and Handling
The Niagara 31 is a masthead sloop—what period specifications also list as a Bermuda rig—with a tall rig whose foretriangle is not excessively large, so foresail handling is reduced relative to many comparable sloops anchor. The genoa sheets on tracks to two coaming-mounted winches, a coach-house roof winch tends the halyards, and additional winches handle reefing, while a 4:1 mainsheet mounted mid-cockpit and a Cunningham, outhaul, and boom vang complete the control suite. With 492 square feet of sail area and a sail-area-displacement ratio of 19.68, Practical Sailor found the 31 excels in performance and does nicely in light airs thanks to that big sloop rig anchor. Owners report she sails exceptionally well on all points—stable, well-balanced, and quick—and the owner of a 1993 model claimed she will outpoint most racer-cruisers. Her PHRF average of 156 and Portsmouth Yardstick of 84.0 place her ahead of the Aloha 32's 171 in the lower-number-is-faster convention. The trade-off noted by Michael McGoldrick is tenderness: she is a little more tender than most cruising boats her size, and the same big rig means most owners say reefing is required at about 15 knots, with nearly all agreeing reefing comes earlier than on heavier cruisers.
Accommodations
Below, the Niagara 31 is a focused cruiser-racer interior rather than a volume play. The galley sits to starboard at the foot of the companionway and includes a two-burner propane stove; the icebox is opposite on the port side in the aft part of the navigation station, whose seat and table both stow away when not in use. The head is forward, just aft of the bow V-berth, separated from the main and forward cabins by folding doors and fitted with a shower over a teak grating. Sleeping includes the bow berth plus two main-cabin settee berths, the port one a double. Ventilation comes from two translucent hatches—bow and main cabin—and of six ports, four are fixed with two opening. One owner summed her up as a technical cruiser/racer not suited to the beginner, which matches the performance-oriented layout and rig.
The Verdict
The Niagara 31 is a small, limited-production Frers design that delivers racer-cruiser pace without abandoning cruising accommodation. Her light-air performance and balance are genuine strengths, but the tender hull and early reefing threshold demand an engaged helm. With only 100 built and a split engine configuration across the run, careful identification of hull number and drivetrain matters more than usual.
Pros
- Big masthead sloop rig with 492 sq ft of sail gives strong light-air performance
- Well-balanced, quick, and outpoints many racer-cruisers per owner reports
- Focused cruiser interior with stowing nav station and forward head with shower
Cons
- Tender relative to most cruisers her size; reefing needed around 15 knots
- Only 100 built; early hulls use Volvo saildrive, later Westerbeke v-drive—two different systems
- Owner describes her as a technical boat not for the beginner
