🦦 River Otter Swim Lab: Wave Drag, Froude Number, Surface vs Dive and the Aerobic Limit

Swim a river otter at the surface or underwater and see why diving beats the wave-making hull-speed wall: friction and wave drag, power, cost of transport, cold-water heat loss and the oxygen-limited dive cycle, with a live Kelvin-style wake and independent numerical checks.
