Unless the teak deck was recently done or the boat is extremely new, it is most likely a mechanically fastened teak deck... which can cause serious water intrusion problems... One easy way to tell if it is a mechanically fastened deck is to look for the bungs covering all the screws...

A glued deck won't have bungs, a screwed down deck will.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
