I really need some help figuring this one out.I have cut out sole out of my O'Day 22 (actually only the top skin and rotten core). The bottom glass 'skin' is intact. There is another layer of fiberglass underneath this 'skin' and above the bilge. It is curved downwards on top of the bilge and I cannot tell how far it extends towards the berths. I need to know what in the world this piece is and what it is supposed to do. The reason I need to know this is because I have water accumulating underneath the berths that doesn't make it into the bilge. An aside, where is water supposed to drain into the bilge from?Also, I am making every effort to fix the leak(s) by rebedding the entire deck including toerail, rubrail and ports. It shouldn't leak after this, but I need to understand how the liner/sole/bilge construction is supposed to work. I feel that something (possibly the 'mystery fiberglass' sheet) has gotten compressed/broken and is not allowing water to drain to the bilge.Thanks for your help.
