The boat was tested in the water for one hour, and did not sink, or show evidence of sinking at
The damage shown to the mast left occurred when a student flicked the design, and it hit directly the edge of the pool. This caused the mast to break off (as shown). However while the mast itself would sink when held below the water, the base of the boat would not even when it was held underwater on the base of the pool.
Given all the testing that was carried out in the last two days the design is practical in terms of its water durability and water tightness, a regular print will not sink as the PLA continually refloats. This design as shown while it is basic represents the first basic print and design in the series. The inention is for the students to design, manufacture and mount a motor onto the boat to allowed it to be semi-powered which will provide the next challenge for students.
