Madagascan lemur; a nautical term showing compliance (3,3)

I believe the answer is:

aye aye

(Other definitions for aye aye that I've seen before include "Sort of lemur" , "Yes, indeed" , "one of 28's local relatives [=>MADAGASCAR]" , "Rare creature of Madagascar" , "Yes, skipper!" .)

I've seen this clue in The Times.
