Would David Beatty have been better suited to command in the age of sail?

Possibly: slower tactical movement offered more time to correct flag signals, although communications would still be a weakness.

Beatty might have been more effective in an age-of-sail battle because fleets moving at roughly ten knots gave commanders longer to recognize and correct a signaling mistake. An incorrect flag hoist could be hauled down, blamed on a junior signalman, and replaced before events moved as quickly as they did in a steam-era fleet action. That extra time would play to Beatty's appetite for dashing action while reducing the immediate cost of confused communications. This remains a counterfactual judgment, and his signaling problems would not simply disappear.
