Dutchman Marks
Hi Peter,I feel that I already replied to you on this but it does not show under the responses so here we go again and apologies if you have already seen it.I had the same problems as you with my Dutchman system. The surface of the cloth goes black when rubbed by the vertical lines and the sailcloth fibres are changed. After cleaning the marks remain and it is not dirt.Soon you will also have permanent marks where the sails fold every time you stow them plus other marks where they contact the mainsheet blocks. The black plastic material of the Shaeffer blocks seems to transfer to the sail. Oh then any oil in the blocks gets onto the sail too.I have abandoned the Dutchman after three years and a spoiled mainsail and have now made a sailcoat and lazy jack system combined. Now I zip up the sail every time we go into port. It is much tidier and the sail is protected against UV. Previously it was too much bother to fit the cover with all its fiddly zippers over the Dutchman lines etc.Wish I had the benefit of this advice three years ago. If you want to preserve the looks of your sail do not delay in changing. Most UK sailmakers have been supplying these sail covers for many years and they now seem to be catching on in your country too.I have never seen a Dutchman supplied as original fit on a UK made boat.Regards,Don
