Service scales with size. For six, DIY snacks are fine; for twelve, assign a food zone and a trash plan; for 25+, hire a steward or two so the host isn’t stuck juggling cups. Shade is non-negotiable in hot months—umbrellas tip at sea, so rely on built-in canopies. Confirm power outlets if you’re bringing extra lighting or a DJ controller, and ask about generator noise. Finally, respect the safety brief on weight limits for bow and flybridge. Comfort comes from space to breathe, not just max capacity.
