April Tools Video

[gfish]

I'm still working on a full April Tools write-up, but I edited all the video together last night. So if you've ever wanted to see me repeatedly tip over/sink in a very small, hastily constructed boat, today is your lucky day! (You'll just have to add the Yakety Sax soundtrack yourself.)

My inner physicist is ashamed of not being able to analyse the stability of your craft in a rational way. I'm afraid I couldn't do any better than you did. Though after the fact, I think I'd make a square tub and say to heck with streamlining.

the issue is roll stability. i can't do the exact math, but the general idea is to look at dVolume/dTheta; positive roll stability requires that as your roll deviates from vertical the displaced volume increases. A square cross section like we have doesn't do that (neither does a circle; various triangles and involutes and such do).
