As a gimnasium school project, my two sons would like to repair a Laser sailboat. They have already got a broken boat hull, which they could acquire for free. Now, they are looking for other parts to make a complete boat - from mast and sail, over rudder and keel, to the pulleys and small loops where the ropes go, they don't have just anything. As it is a school project, their budget is very (very, very!!!) limited.
