Hulls repainted and now leak. What could be the cause?

I just had my 1984 16" boat hulls repainted. It has never taken on water before, but now after a short sail we look into the inspection ports and can have as much as 6" of water.

Any advice?

Hmmm, I guess we need some more info here.
Were the hulls removed from the frame? If so are the foam plugs in place?
Was hardware removed? Was it reinstalled in a suitable way?
Some of the older Hobies have the deck to hull seam siliconed. I could imagine the silicone was removed as part of the prep work for the paint job. This could either fixed with new silicone or epoxy.
If nothing I described seems to apply try to detect the leak by creating mild air pressure in side the hulls (reversed shop vac connected to port hole or drain plug), use soapy water for detection.

The hulls were removed from the tramp frame. I am not sure about the "foam plugs". Where are these located?

The deck and hulls look to be one piece and don't have silicone joining them.

Thanks for the reply.

It is some closed cell foam inside the aluminum pylons - the stuff has the reputation to age and crumble.

Nee... all Hobie 16 hulls are made in two pieces - deck and bottom part - those are later joint together. This is not a uncommon place for a leak. \
