Design 1986 - Niagara

As it happens sometimes we can't find images that go along with the plans. I have been looking for images of this particular boat for quite some time and found these misfiled with another design. In any event, these are the only images we possess for Niagara and we're glad to have them.

Niagara was designed and built strictly for Canada's Cup racing. She was constructed of fiberglass with a balsa core by Bristol Yachts of Bristol, Rhode Island and launched in 1969. Her accommodations are actually more luxurious than required but produce a great layout.

Note the hollow in her stem profile, which is rarely seen in our archives.

Here are the plans. In regards to the sail plan, please note the permanent midstay or "babystay" and removable inner forestay along with the lower diagonal which is angled aft which was standard practice during this period of time.

Regarding the general arrangement and inboard profile plan, please note the engine located amidships, the horizontal propeller shaft which passes over the trim tab shaft and quadrant, the necessity of an intermediate coupling and pillow block due to the overall shaft length and the aperture well aft and just forward of the rudder.
