Livo 3

thingiverse

**Dual #MakeItFloat and #CatchTheWind entry** This is the Livo 3, a trimaran (three-hulled sailboat) designed for speed and stability. Its two outer hulls can swing into three different positions: - In its fully extended configuration, it provides maximum speed and stability, especially in side-wind. - It can also be configured to have its out hulls at an intermediate distance from the central hull, swooping backward for increased maneuverability in tight areas. - Finally, it can be closed with its outer hull adjacent to the central one, occupying minimal space on a trailer or when docked. This is the third boat I've made as summer vacation projects. The first two were not 3D printed but carved in wood. The files are still temporary, but when complete, the boat should be fully functional and steer well with some wind based on previous test results. Coins will be used as moveable ballast on the leeward side to keep the boat level. Any suggestions, especially sailing/nautical ones, will be greatly appreciated. Apologies if my terminology is not proper :). **Updates** v 1.1: - The keel has been changed to a removable "daggerboard" to accurately represent modern trimarans. - The crossbar connecting the rudders now has a more aerodynamic shape and a handle in the center. v 1.2: - The rudder was modified to 'flow' with the crossbar. - A cap for the boom and mast was added to hold the sail/rigging. - The hinges pins were strengthened, and hooks were added to secure hulls in the desired position with string or rubber bands. v 1.3: - The rudder hold in outriggers was modified to make it simpler to print. - The rudder was re-sized accordingly. - A coin ballast holder (sized for dimes) was added. - The pins were re-sized with better tolerance, and hookups for boom-line and sail-line were added. v 1.4: - The model was cleaned up so it can slice and print. - The coin ballast holder was modified with a flat bottom for easier loading. v 1.5: - Individual STL files were uploaded with some minor modification after printing all the small parts. - A kitchen skewer was used instead of a 5mm dowel for the mast, and the sail is made of a plastic file folder. - A base holder will be designed if there's time. Due to printer limitations, large pieces won't fit. We'll cut them into smaller pieces, print them, and glue them together. A 'collar' was added to the daggerboard holder to keep it tight after regluing. It's not required if the print is in one piece. **The Water Test!** It floats!!! The glue seals seem to be holding well. The boat is relatively low on the water but moves around happily. **Coin Test** At first, it only held 17 coins before taking in water. However, after careful placement of more coins towards the bow, it held up to 24 dimes (12 per side) with a few more added before sinking.
