Sunfish Sailboat Model

<h1>Post your MAKES</h1> I made another floating marker, but I made this one so it actually sails too. I used some Sunfish sales catalogues to get the hull lines right. The sail is deliberately slightly undersized for reasons of weight/balance. Use a 1/8" (3.5mm) steel rod for the tiller/rudder. You may want PTFE tape to tighten up the tiller fit. <h1>Notes on the Sail</h1> After the sail is printed, - Remove it, trim, and return it to the print bed. - Reheat the bed to an annealing temperature. Say 60-70C for PLA - Take the heated sail and manually deform it into a very gentle airfoil. The corners should be deflected by 2-to-5 mm from their "flat" position. The airfoil for the sail comes from two factors: the shape, and the fact that the printbed-side of the sail will be smoother than the topside, meaning there will be differential airflow.
