My old club racer (v1) had a few issues,
It was based on a Stealth Military Craft (24in).
1 Would submerge if hit in the rear by another boat.
2 if flipped would not self right (not sure if new one will)
3 Not great in choppy water.
Sacrifice v1 to provide running gear.
New scratch build boat has a deeper 'v' profile, a few inches longer (27.5)
