Turns🚤 Boat

Spinning out in turns

The boat snaps sideways and spins mid-turn instead of carving through it.

💡 The idea: Reduce prop blow-out and rebalance a catamaran's sponsons.

Try these in order

Make one change at a time and re-test — that's how you learn what your car likes.

  1. 1
    Reduce negative rudder caster

    Excess negative caster causes prop blow-out and hop mid-turn.

  2. 2
    Add sponson weight opposite the spin direction (catamarans)

    Corrects a one-directional spin-out on tunnel hulls.

  3. 3
    Check turn fin alignment

    Must be parallel to the sponsons with zero toe.
