Once the kids sit in the right position, Im sure the bow will sit in a bit further, probably doesn't help that Billy's son is 12 kg below what it was designed for either. If I have to change anything it will be to add a bit of volume aft but Im loath to do that as I wanted the boat to be largely pitchpole proof so we don't scare the kids while they are still learning.
We will learn more this weekend when they are out again and hopefully we will see a bit more breeze so that they can push the boats a bit harder.
