Im 92 kgs and used to up haul on a 130 ltr, was a tad wobbly, you just tend to wanna learn to water start faster, if you want to learn to water start make sure its really windy so you get the feel. Drag ya bum, have straight arms, let the wind lift you up and stay low until powered up.
Dont worry you will know what I mean. It's a good thing

Cheers
