Hi I'm Ethan and I spent large amount of time on what I would call a very interesting project.

Step 1: What Made Me Choose a Sailboat.

For about a year now I have been following the progress of the Tally Ho project. The YouTube channel Sampson Boat Co documents the mission to rebuild the 110 year old classic sailing yacht Tally Ho. Ever since I started watching this project I have been intrigued by the detail and design that goes into a sailboat. When I began this project I severely underestimated the difficulty of doing this project on Inventor and overestimated my AutoCAD Inventor skills. Although through the 11 hours I have spent trying to design and fix the endless errors created by those designs I can happily say that I'm proud of what I made and that I have progressed my inventor skills.

Step 2: Understanding the Design

I got the design for this boat from studying other ships rib sketches and designs. I used CAD Inventor to spline the shape of each rib to create the shape of the hull. The 3d model required a large ammount of work to get it to print correctly.

Step 3: 3D Printing

To print the boat I put the files into my slicer and scaled them up to 643% because of how its loaded in. The hull should add up to be about 20 inches or so. make sure to print with the largest flat surface of each part as the base to prevent warping. In you slicer's settings your going to set infill to 0 and the top and bottom layer to the minimum thickness so that you can cut the parts open. Although for the bow and stern only change the settings for the first layer. After that you should have all 6 parts done. You will also want to sand out the hole that the mast will insert into.

Step 4: Assembly

For assembling the parts I used 15 minute Resin. you should attach sets of 2 and think of where you want it to split. I chose to have the split be before the mast as shown by the black tape. The split is where I put in all of the electronics. When sealing up the split part of the boat I used hot glue so I could peel it away and reopen it to access the electronics. I know that's not the best way but I was trying to stay away from designing a hinge door on the deck.

Step 5: Electronics

For the electronics I tore apart an old RC car for the servo and receiver with matching remote. I went to a hobby shop and bought a AA battery pack for the power supply. The Servo was placed into a cut out I made in the deck with a Dremel and the rest was placed inside. Remember that depending on what your using for ballast and where it is in the boat you might have to take into account where the battery pack is placed.

Step 6: Ballast and Rudder

For the ballast I used stainless steel bb gun ammo because of how heavy it is and that is more or less form fitting. you can use other materials for ballast but take into to account how you will secure it in place. The rudder is made out of a cut as sanded paint mixer and the shaft is a shaped piece of solder with a rivet head hammered onto the top end to make sure the servo doesn't disconnect.

Step 7: Mast and Lines

Around the hull are two loops and two rods that are used as tie down points for the lines the attach to the top of the mast. Mast was also assembled using resign. Once you insert the fully assembled mast you should take string or wire and tie each of the four points to the top of the mast. Once the lines are done I cut out the mainsail using a Zip-Lock bag. the joints are made of tape and the beam along the bottom of the sail is another piece of solder.
