Speed board volume
Interesting findings today when I measured the volume of my 43 and 41cm speed boards. Always wondered how big my custom Patrik Diethelm 41 was compared to the Patrik production 43.
The 41 is 233cm long compared to the 43 which is 228cm.
I haven't used the 41cm in Luderitz during the past two years because the wind hasn't been great and I have been on the "bigger" 43cm.
Bigger turns out not to be entirely true. I constructed a plywood box 2.445m x 60cm x 14cm, filled it up and then pushed my speed boards under the water. The amount of water they displaced then tells me their volume.
The 43cm, to my workings, displaced 54 litres of water and the 41 displaced 58 litres.
