Boater
straw hat with a straight brim, flat crown and ribbon hatband

A boater (also straw boater, basher, skimmer, The English Panama, cady, katie, canotier, somer, or sennit hat) is a semi-formal summer hat for men, which was popularised in the late 19th century and early 20th century.
It is normally made of stiff sennit straw and has a stiff flat crown and brim, typically with a solid or striped grosgrain ribbon around the crown. Boaters were derived from the canotier straw hat worn traditionally by gondoliers in the city of Venice. The Venetian canotier has a ribbon that hangs freely off the back, and they are frequently edged with a matching color ribbon. Because of this, boaters were identified with boating or sailing, hence the name. Boaters were also identified more with sporting events and universities as well. They were also worn by women, often with hatpins to keep them in place. Nowadays they are rarely seen except at sailing or rowing events, period-related theatrical and musical performances (e.g. barbershop music) or as part of old-fashioned school uniforms. Since 1952, the straw boater hat has been part of the uniform of the Princeton University Band, notably featured on the cover of Sports Illustrated Magazine in October 1955.
This brief starts where responsible research should: with the source description of “Boater” as straw hat with a straight brim, flat crown and ribbon hatband. 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 straw hat with a straight brim, flat crown and ribbon hatband. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 19, 2026. The linked authority identifier is Q2286991. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1952 and 1955.
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.
