Ok, so I have a head shower...not that its ever been used in the head...I stick the handheld nozzle up for rinses at the shrounds. But the water that rains down my mast "simulates" an inside shower...which makes its wat into the bilge by holes, when unclogged. No tubing etc. My guess is that all the stuff under the teak gets wet at some point... and I hope that it continues its merry way. Is Vemiculite SUPPOSED to collect water? What is its purpose...just stiffening? Mine's "cracking up" if you will...
