Niagara 35
sailboat class

The Niagara 35 is a Canadian sailboat that was designed by Mark Ellis as a cruiser and first built in 1978.
Production
The design was built by Hinterhoeller Yachts in St Catharines, Ontario, Canada and first shown at the Toronto International Boat Show in 1978. The company built the design from 1978 to 1990, with 260 examples completed. About half the production run went to customers in the United States.
Design
Ellis explained his design goals for the Niagara 35: "she is a cruising boat that made sense ... Her underwater shape is similar to racing boats of the 1970s ... The spade rudder is balanced and the keel form is a simple NACA foil without deep draught. Her sheer line is moderate and the ends are balanced ... I suppose you could say she is a moderate design, but that sounds dull – I hope the 35 is better than that!"
The Niagara 35 is a recreational keelboat, built predominantly of fibreglass over a balsa core, with teak wood trim. It has a masthead sloop rig with aluminum spars and a bowsprit, a spooned raked stem, a raised counter transom, an internally mounted spade-type rudder controlled by a wheel and a fixed fin keel.

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 1, 2026. The linked authority identifier is Q85788956. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1978 and 1990.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
