We have collected parts for building our next Quadmaran. The floats, solar panels, trolling motors, and aluminum. Also have a welding machine. Had to get the machine here, get it wired up, and get some Argon gas. But learning to weld aluminum and making this boat is our summer project.

3D Test 1
For our first 3D printing experiment we just paid shapways.com to print the design. We also got a new friend in their forum that did the 3D design. We are now learning FreeCAD since that is what he used and it looks good. We can open his design and make small changes so far. The ShapeWays price goes up fast with the weight of the object so we printed 4 very small floats.
This model is really too small to make a good test in the winds of Anguilla. I have always used outdoor wave tanks (pools and ocean) and so don't have control over the wind. This means winds are always very high for my scale models. When I get to 5 foot models it is like we are testing house size boats in simulated hurricane conditions, which is ok. But smaller than that does not really work. But the point this test was really to test 3D printing. That did work.
We have ordered a 3D printer so we can print our own larger floats and will do so as soon as it gets here. Takes a couple weeks for stuff to get here.
