I was asked to share the template I used to create the feluccas in the previous post, so here it is. It can be scaled up if needed.
The feluccas I made are based on 3/8th inch foamcore cut to shape, with cereal packet card for the sides and stern. I used Aileen's glue for the curved lengths of card around the hull, tacking them in place using a hot glue gun to hold them while the stronger Aileen's glue dried. Card can be used for a deck if required. It might also help to use another deck-shape cutout to base the foamcore hull on for added strength. I used a mini-dowel for the mast. Note that with the felucca rig the mast is comparatively short and thick. The diagram shows its location in relation to the yard. The felucca sail is just a triangle with one point cut off. I made mine from stiff paper with the yard being a thin strip of cardboard glued along the upper edge of the sail. It's best to assemble the mast, yard and sail before mounting it on the hull.
