Type of vessel in which François Gabart broke an around-the-world record in 2017 (8)

I believe the answer is:

trimaran

(Other definitions for trimaran that I've seen before include "Three-hulled craft" , "Sailing boat with three hulls" , "Three-hulled vessel" , "Three-hulled yacht" , "type of boat" .)

I've seen this clue in The Times.
