Design and Construction
Hinterhoeller built the Niagara 35 with balsa coring in both hull and deck, using unidirectional rovings and bonding all structural bulkheads to the hull. The keel is massively faired into the hull with a substantial sump, and the chainplates tie into accessible interior knees heavily bonded to the hull. A bridge-deck keeps the companionway secure, and raised bulwarks give a far greater sense of security than mere toerails. Writing in Cruising World, one longtime owner described a sudden encounter with a rock in poorly charted Georgian Bay that assured him Hinterhoeller built a tough boat; no water came in, and the only visible damage was mangled lead on the leading edge of the keel. The hull is semicored and needs to be monitored, and Niagara 35s aren’t known to have blister problems.
Rig and Handling
On deck, a short bowsprit extends the foretriangle and supports double anchor rollers, with a rod bobstay making anchor handling easy. The keel-stepped, single-spreader rig is staunchly supported with double lowers and originally used Navtec rod rigging. Later models came rigged with an inner forestay on the large and secure foredeck, and many older ones have been similarly retrofitted once duly reinforced. Jibs can be sheeted to an aluminum toerail on the bulwark or to an inner track on the wide side decks, while the mainsheet traveler sits out of the way on the coachroof. Owners report the boat tracks and maneuvers well and rate her handling as above average, though off the wind some say she doesn’t track as well as she could. She is stable and stiff under way; one owner noted the rail of his boat went in the water only once, beating down Lake Huron in 20 knots, and he achieved over 8 knots downwind on a day when few others were out. Practical Sailor found her smaller sailplan suits her more to breezy conditions and offshore work, and that she cuts through the seas better than her smaller sibling, though she is not so fast nor closewinded and points respectably rather than sharply due to wide sheeting angles. Sail trim and the right sail combinations really make or break progress upwind or in light air.
Accommodations
The Classic interior is an unusual but intelligent design for extended coastal cruising for a couple. The companionway leads to an aft cabin with a smallish double berth to port and a quarter berth to starboard, plus a stand-up nav station on top of a large dresser at the head of the quarter berth. Doors lead from the aft cabin to the head and galley, and another opens to the head from the saloon. The saloon is largely forward of the mast, with over 6 feet of headroom, lit by four fixed windows, four opening ports, and four hatches; with doors open you see the entire length of the boat. Settees either side of the drop-leaf table make excellent sea berths with lee cloths. In the Classic, the forepeak is devoted to stowage — workbench, shelves, seat, and lockers — while the later Encore version places a conventional V-berth forward. Practical Sailor notes the Classic’s settees run 6 feet 7 inches and the aft double 6 feet 4 inches, with headroom 6 feet 4 inches in the main cabin and 6 feet 2 inches aft. Oiled teak bulkheads and joinerwork with varnished pine strapping complete the finish, and a drained, vented propane locker aft holds two 20-pound tanks.
Known Issues
The principal watch items are the balsa cores. On older boats, the decks of balsa construction should be examined for moisture intrusion around fittings, and the semicored hull more broadly needs monitoring. The cockpit is quite large — good for lounging but, as one owner observed, too wide for bracing the feet when heeled.
Refits and Ownership
Many older Niagara 35s have been retrofitted with an inner forestay once duly reinforced, bringing them in line with later factory practice. The engine sits behind the companionway stairs and is more accessible than on many boats this size, which eases routine service. A deep chain box low in the bow can be divided for chain and rode, and a Paloma instantaneous LPG water heater was a universally liked option. Original deck hardware included Barient (later Lewmar) winches and Atkins & Hoyle hatches, with massive chocks and cleats per owner description.
The Verdict
The Niagara 35 Classic is a thoughtfully laid-out cruiser with a genuinely tough, well-bonded structure and a stiff, predictable manner in a blow. Her forward-workshop Classic layout rewards the self-sufficient couple, and her accessible engine and secure bridge-deck suit long coastal use. She is no lightweight racer, but she carries her length with composure offshore.
Pros
- Stiff, stable hull with proven ground-tolerance and no blister problems
- Secure bridge-deck and raised bulwarks; accessible interior chainplate knees
- Intelligent Classic layout with full-length sightlines and proper sea berths
- More accessible engine than peers of this size; easy anchor handling via bowsprit
Cons
- Balsa core in hull and deck demands moisture vigilance around fittings
- Wide cockpit hinders foot-bracing when heeled
- Modest upwind angle and light-air performance hinge on sail trim
- Considered by many bluewater sailors too small for round-the-world use
