Glass boat (8)

Ross

I believe the answer is:

schooner

This clue is a double definition.

'glass' is the first definition.
(schooner is a kind of glass)

'boat' is the second definition.
(schooner is a kind of sailing vessel)

(Other definitions for schooner that I've seen before include "No chores on this sailing ship" , "Sailing vessel used in former times" , "Swift sailing vessel - sherry glass" , "9 [CONTAINER" , "wooden vessel" .)

I've seen this clue in The Sun and the Sydney Morning Herald.
