Boat strike? (5)

I believe the answer is:

smack

I believe this is a double definition.

'boat' is the first definition.
(smack is a kind of sailing vessel)

'strike?' is the second definition.
(thesaurus)

(Other definitions for smack that I've seen before include "Sharp slap" , "Hit - kiss - fishing boat - heroin" , "Heroin (sl.)" , "Hit with an open hand" , "Slap the fishing vessel" .)

I've seen this clue in The Globe and Mail.
