I am by no means a novice but nor a veteran boat owner. However we have just bought a taylor t500. Basically it's a 16' grp fishing boat with a fairly standard shape set up. It has no bilge area...it seems to be sealed.
We took it out for the first time today and it ran lovely and stayed dry inside pretty much.
My question is upon taking it out of the sea, water flowed out of two "drilled"(?) holes in the rear of the keel! Is this normal? Are they meant to be there? Is it part of the design for buoyancy?
Please help

PS. It isn't the drain plug, these holes are in the bottom by the keel
