Smallest working sailboat (?)

An attempt to make a tiny working sailboat. Works best going at 90° but it may just be able to go at 45° against the wind??? No sailor experience! Please be kind :) I found it easier to trim than my miniature inflatable raft. Having two sails I can loosen the prow sail so that the aft sail does the work but also makes an aft drag that turns the boat windward, somehow balancing the tendency to turn with the wind. Construction: Hull made out of a cork (cutting pattern coming soon) Sails are plastic bags for sandwiches. Also dog poop bags will work, since the plastic is really thin Masts are made out of a wooden toothpick and a cotton swab Rigging is sewing thread Fins are from a credit card Ballast is a sinking lead
