# =============================================================================
# Default PID tuning — 40 m planing motor yacht
# =============================================================================
#
# WARNING — Conservative bench/start values only.
# Scaled from the 30 m profile to account for the larger vessel: higher mass
# moment of inertia and longer time constants. Compared to the 30 m profile:
#   - kp slightly lower (slower response per unit rudder)
#   - kd slightly higher (more anticipation needed for the inertia)
#   - setpoint_rate_limit_dps reduced (gentler heading slew)
#
# As with the 30 m profile, these are commissioning starting points and
# must be replaced with the integrator's production tuning.
