Jim & Joan: OK, you have some great photos for sure I know. Just put up a big tight white sheet on the viewing side of the vessel, or one on both sides/aft if you want. Set up one of those overhead projector one eye'd monsters and your laptop on the oppisite side of the boat, projecting the images and history onto the back side of the sheet. Set the laptop and projector on a table, and just move the table/projector to the other side if you have to turn about. Everybody loves history, particuarly when gathered around the waters. My guess is that you have some of the best photos taken of the lighthouse. Let the real light house shine to the folks on the banks. Saw this set up on a yard display telling the Christmas story. Great stuff. Not sure how large of a projection image you can get with the projector only 8' away...but, if you set it projector up front, and the screen aft.... 25' would give you a good size pic projection....or, a great opportunity to let some nice equipment get doused. We have used tupperware containers as protectors for the projectors outdoors and in tents and cut a hole for the light/projection to shine thru. Be sure to use clean sheets....cause once lit up....everything shows....even the cat walking between the projector and sheeet. :disgust :xnaughty
