    Good morning,
    Just joined the forum as need advice ,
    I have been using small fishing boats for 20 years or more but don’t know a lot about there actual build etc .
    I have recently got hold of a smaller one for single use etc
    It is GRP , it has a floor void in it with three plugs .
    I washed the boat out the other day and this void filled with water ?
    What is the point of the void Please ?
    I can only imagine the water got in from two pieces Of wood the cross the deck ?
    Or is this void for water ?? Any ideas please ?
    I need to make it water tight .
    Thanks in advance

    Hello Tom - a photo is worth a thousand words, so if you could post a photo (or two) that would help a lot.

    I am a bit baffled by your description above, and I think that Hoyte is as well.

    I am surprised there is no bilge drain on the transom. I have never seen bungholes like those placed in that manner. Have you any documentation of the boat's origin or manufacturer?

    There is a bung hole in the bottom corner that drains the Boat deck out .
    Those bungs in the picture are for this chamber below the deck .
    I intend to make sure it stays dry by sealing the wood on the deck .
    But still can’t figure out why it’s there ?
    Thanks it’s an old boat .

    I am still rather baffled - are the two bung holes in the top photo draining overboard through the hull bottom? Are they along the centreline of the boat?
    Do you have a photo showing the hull interior from above, including the 'chamber' below the deck?
    (What is this chamber used for?)
    What wood will you be sealing on deck - does this include the section of bare timber shown in a couple of the photos above?

    The hull looks like it was built using a mould taken from a traditional clinker / lapstrake timber rowing boat.

    The two pieces of timber are screwed to the deck of the boat
    which is where I think the leak is as to water going in the chamber .

    . No there is one hole That goes through the hull to allow the boat to be washed out .
    The other three bung holes are in to the chamber .

    I bet a former owner installed a live well circulation system. Those are it's inlet and exhaust ports.

    It is difficult to tell by the photos if the bung holes are in a vertical or horizontal surface. Is it at the bottom of the bulkhead on the forward tank?

    I would not seal it too tightly. Changes in temperature and pressure could cause structural fatigue leading to a leak in some inconvenient place.
