Summary

Dual #MakeItFloat and #CatchTheWind entry

This is the Livo 3, a trimaran (three-hulled sailboat).

Its two outer hulls swing into three different possible positions:

It can be locked into the fully extended configuration, which is the predicted main sailing configuration and should provide maximum speed and stability, especially in side-wind.
It can be configured into a middle position with the out hulls at an intermediate distance from the central hull, and swooping backward, for increased maneuverability in tight areas.
Finally, it can be 'closed, with the outer hull adjacent to the central one, as to occupy minimal space on a theoretical trailer, or when docked at port.

This is the third boat, in a series that I have made as summer vacation projects (hence the name and the three hulls), although the first two were not 3D printed, but carved in wood.

The files are still temporary, but when it is done the boat should be fully functional, and steer well, as well as go at a decent speed with some wind, based on results with previous tests.

Coins (in dedicated slots) 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 the terminology is not proper :).

Updates

v 1.1

The keel is now a removable "daggerboard" to more accurately represent modern trimarans.
the crossbar connecting the rudders has a more aerodynamic shape and a handle in the center

v 1.2

modified the rudder to 'flow' with the crossbar
added a cap for the boom and mast to hold the sail/rigging
strengthened the hinges pins
added hooks to secure hulls in the desired position with string or rubber bands for extra strength
made crossbar angled
added the 3 separate crossbars for each position

v 1.3

modified rudder hold in outriggers to make it simpler to print
re-sized rudder accordingly
added coin ballast holder (sized for dimes)
re-sized pins with better tolerance
added hookups for boom-line (in the back) and sail-line (in the front)

v 1.4

cleaned up model so it can slice and print
modified coin ballast holder with flat bottom for easier loading

v 1.5

uploaded individual STL files with some minor modification after we printed all the small parts
couldn't find the 5mm dowel for the mast so we decided to use kitchen skewers. the mast base and top were modified accordingly, and a connector was added to get enough length (files are called ****skwr)
the sail is made of a plastic file folder
we also designed a base holder, we'll put it up if there is time
our printer only does 10x10x10 cm, so the hulls, rudderbars and other large pieces don't fit. we will cut them and print them in smaller pieces, then glue them.
for the side hull we incorporated slots and connector to make the assembly easier and sturdier.
added a 'collar' to the daggerboard holder, to keep the two pieces (rear and middle) tight after reglueing. it is not required if the print is in one piece (still looks good ;))
When you award us the new printer, we will be able to print them whole! :)

when the boat is assembled, we will finally be able to test how many coins can the outriggers carry !

since there are already a ton of files and pics, we will document the build in the connected "I MADE ONE" page

THE WATER TEST !

it floats!!! :) :)
the glue seals seem to be holding well.
the boat is relatively low on the water but it moves around happily.

COIN TEST
at the first try it only held 17 coins, dispersed on the outriggers, before starting to take in water. the water came in from the back, and a lot of the coins where on the stern side.

tried again but with more care of putting in the dimes more towards the bow.
the picture above is at 24 dimes (12 per side), another 4-12 or so can be added before causing the boat to sink. it needs to be done with caution and the placement is important.

if the coins were also put in the main hull, the number raised up to 52 before it sunk.
with careful placement i think that the $6 limit could be reached
