Do all surfboards have this friction factor? And do you find it as a bad parameter?
If you look at the angle your thruster fins are set, you'll see why there's so much friction:
Both outer fins are generally aimed at the nose of the board, plus they are flat on the inside and foiled on the outside (like wings) to generate 'lift'
This is so you can slash up a wave face and carve hard turns....
But going in a staight line with the board flat in the water, it's like having little water-brakes permanently applied.
So a great thing when you want to dance on a wave,
a bad thing when you want to hum along in flat water (which is why TT's were invented
