Vessel provided by club carrying granny with neckwear (6,4)

'vessel' is the definition.
(I know that banana boat is a type of cargo vessel)

'club carrying granny with neckwear' is the wordplay.
'club' becomes 'bat' (as in sporting equipment).
'carrying' is an insertion indicator.
'granny' becomes 'nana' (both can mean a grandmother).
'with' is a charade indicator (letters next to each other).
'neckwear' becomes 'boa' (boa can mean a scarf).
'nana'+'boa'='nanaboa'
'bat' going around 'nanaboa' is 'BANANA BOAT'.

'provided by' acts as a link.
