n. — Fishing, also attributively, e.g. fishboat skipper, fishboat owner, British Columbia
a fishing boat.
Type: 5. Frequency — The more frequent term in Canada is fishing boat. Changes in noun compounds from the long form with -ing to the short from without it have been ongoing for more than a century and depend on the lexical item, e.g. dump truck has long outnumbered the original dumping truck (Dollinger 2015b: 181-183, see note in drinking box). Fish boat or fishboat has some currency in Canada as in other countries (see Chart 2) and is especially common in BC (see Chart 1).
See also COD-2, which marks the term "Cdn (esp. BC)".
