Glass vessel (8)

I believe the answer is:

schooner

This clue is a double definition.

'glass' is the first definition.
(I know that schooner is a type of glass)

'vessel' is the second definition.
(type of ship)

(Other definitions for schooner that I've seen before include "Item used for drinking" , "9 [CONTAINER" , "Two-masted sailing ship" , "Sailing vessel - drinking vessel" , "wooden vessel" .)

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