Since 1989 we have lived and cruised as far as Australia in our old boat,an Oyster 435 from which we switched Bali Hai No 319 early last year,this was a vast improvement over the slow leaky Oyster. Since then we have sailed to the Med and been in a force 10 storm with no problems. We have no problems with the windscreen design.A piece of wood one inch by two inches by six will prop the window open as required. So far as the bimini top is concerned Amel retrofitted (welded) clear panels in the front and centre sections of the Vynil.If we had known this would have been a free or low cost item but there is a lot of time involved in taking the frame off.We then made up a white plastic patch which is attached to the underside with Velcro so that it can be removed as necessary. It works very well.
