E&B WEST Marine has all the materials and equipment you need to shrinkwrap your boat. Well almost. You can get the strappings from any lumber yard. There is a store on the junction of 93 and 95 south in Woburn. There is one on Rte 1 in Portsmouth. It's a long haul but I get my antifreeze, oil and gas stabilizer at the same time. A one stop shop. At this time of the year there is a big sale going on so it pays to look around.
