we found weight to be critical to good performance.
A simple Styrofoam boat waaaay outperformed our balsa wood constructed catamaran.
We tested quite a few different ideas… ultimately, weight was king.
I mean featherlight weight!
I don’t know what your rules allow… since I effectively got to write our rules, I made darn sure there was no restriction on boat material.
We had a Styrofoam hull, flat-bottom single piece design… and water-based clear coated printer paper for a sail (this way you can print a pattern on it).
If we ever try this again (no race this year, and my son is moving on to Boy Scouts…)…
I would want to try adhering a film of plastic food wrap to the bottom of the styrofoam hull… I’d have to weigh it all though…
we’re talking grams, not ounces for the weight of such a boat!
We had 6 foot lanes… way too short… my son ran them in just barely over 2 seconds after lots of practice.
Just playing, one time (luck more than skill) I managed to huff the little boat all the way down the lane… if timed, that run was under 0.5s!!! It was nearly impossible to repeat (think maybe 1-2 repeats of probably 50 attempts). If someone could figure out a perfect technique… it would be something else… even on a 10ft lane… a 2 puff, sub-2 second run would be possible.
