I am restoring a Vega 27, hull 709, and need to repair the bilge floor. Due to sitting outside neglected for many years water froze in the boat and broke the corners of the bilge floor. Water is now below the floor level inside the keel. I drilled a hole through the bilge floor and found what appears to be a rubber bladder. I was wondering if anyone has completed repairs like this. I am hesitant to tear the floor out and dig into the keel because the space may be too confined to properly put it all back together again. Mark
