Spinnaker
forward sail
A spinnaker is a sail designed specifically for sailing off the wind on courses between a reach (wind at 90° to the course) to downwind (course in the same direction as the wind). Spinnakers are constructed of lightweight fabric, usually nylon, and are often brightly colored. They may be designed to perform best as either a reaching or a running spinnaker, by the shaping of the panels and seams. They are attached at only three points and said to be flown.
Etymology
Some dictionaries suggest that the origin of the word could be traced to the first boat to commonly fly a spinnaker, a yacht called Sphinx, mispronounced as Spinx. Sphinx first set her spinnaker in the Solent in 1865, and the first recorded use of the word was in 1866 in the August edition of Yachting Calendar and Review (p. 84). In addition, the term may have been influenced by the spanker, originally a gaff rigged fore-and-aft sail.
Another suggestion is that the idea for the sail was conceived in 1865 by William Gordon, owner of the racing yacht Niobe. He wanted to name the sail after his yacht but a crewman's comment, "Now there's a sail to make her spin" became "spin maker" which developed into the commonly accepted term spinnaker.
This brief starts where responsible research should: with the source description of “Spinnaker” as forward sail. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as forward sail. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Jul 29, 2026. The linked authority identifier is Q1137340. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1865 and 1866.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
