Hi I have a 640 and I have just scrapped the hull and found a rubber bung amidships port side is it a drain for the cabin as the cockpit bilg had water so i drained it 10mins later it had more, then I found two holes going into the cabin area?? DO I have a problem OR is it something simple I can, any help I can get would be grateful as this is my first shetland I'm lost as to were to start? rgds frank

Hi paddywak,
The underfloor in the cabin should be a floatation tank I believe in case of the boat taking on too much water when in rough weather, and should be airtight keeping the boat on the surface should the worst happen.
Unfortunately in time the sealing breaks between the cockpit and the cabin bulkhead and also at the bottom of the lockers under the cabin seating. ( I had the skinfitting from the sink drain sheer off and the sink drain fell inside leaving a fairly large hole just above the waterline). Woke up at 2am with 2 inches of water in the cabin. Simple repair, £8 for a new brass instead of plastic skinfitting, but the mess inside the cabin was another matter, and clearing out the water under the cabin floor was a pig.I had to cut a hole under the cabin step to pump it out, then reseal it
The Plug in yours was probably put in as a means of draining any water out of the cabin underfloor.
The answer is to reseal the bulkhead between cockpit and cabin and inside the lockers, make sure the plug is well sealed and also make sure no water is getting in elswhere.
Once done any water should stay in the bilge under the cockpit where i have a bilge pump and not get into the cabin area.
Hope this helps
