Evening—Regatta Day
caught the crab
Rowing term for when an oar gets stuck in the water or misses it entirely—a catastrophic mistake in a race. The rower's blade digs too deep or skips the surface, throwing off the boat's rhythm and speed.
Craigie's Whaler
Naval slang: a whaler is a large rowboat carried on warships. "Craigie" likely refers to HMS Craigie, a rival ship in the regatta. This is ship-versus-ship competition.

Emperor Nero famously tortured Christians. The crew is half-joking about their planned beating—"playing at" suggests theatrical violence, though the keys-on-a-belt are real enough.
Port Mahone baboon
Port Mahon (Menorca) was a major British naval base. Calling someone a "Port Mahone baboon" suggests he's from a backwater posting—an insult to his seamanship and origins.
