I think that the problem is that many fabricators DO NOT put baffles in the skin tanks to direct the water from side to side. The skin tank on Earnest is not partricularly big and we have never had the over heat bleeper go (95 degrees C) apart from when the water pump belt broke. -- Neil Arlidge - NB Earnest / Barge Maurice A (on the drawing board) Follow the traveled TNC at : http://www.tuesdaynightclub.co.uk ------------------------ Yahoo!
