Marinas look orderly from the water: rows of white hulls, tidy finger piers, a fuel dock with a flag snapping in the breeze. Up close they are small neighbourhoods, and like any neighbourhood they run on customs that never make it onto the bulletin board. The posted rules cover speed limits, pets, and trash. Everything else, from how you handle a line to when you run the generator, decides whether your neighbours wave or wince.
None of it is written down, which is exactly why new boaters get sideways looks for things they had no way of knowing. Here are ten unwritten rules, grouped the way they actually come up: arriving, living alongside people, and looking after the boats around you.
Fenders and lines go out before you turn in, not while you are drifting sideways toward someone's bow. Fenders on the side that will touch, set at roughly the height of your neighbour's rail, and at least one line led forward and one aft so you step off with something already in your hand.
Practise on an empty end tie or a quiet mooring field until the motions are boring. Then brief your crew in plain language: "You take the bow line, wrap it around the cleat and hold. Don't jump." Handing a line to a nervous guest and shouting instructions at the last second is how fingers get hurt and gelcoat gets chipped.
The dock is full of people who want to be useful, and the quickest way to irritate a skipper is to grab a line off their bow without being asked. A boat approaching a tight slip is a machine in motion with a plan behind it. Your helpful tug can undo that plan in half a second.
So ask: "Want a hand with the bow line?" If the answer is yes, take the line they hand you, do exactly what they say, and nothing more. Hold, walk, cleat, stop. Don't pull the boat in by hand, don't step aboard uninvited, and don't push off a piling with your foot on someone's topsides.
If you are the one docking, be specific about what you need. "Take this line, put it on the cleat, then just hold it." A skipper who says what they want usually gets it, and nobody feels like they guessed wrong.
Sound carries across flat water in a way that surprises people who are used to houses. Posted quiet hours are the minimum, not the standard, and most marina residents are awake earlier and more lightly than you expect.
A few specifics. A halyard left slack will slap a mast all night; pull it snug or clip a bungee to it. Generators, engines, shop vacuums and power tools are morning noises. Running a generator at dawn to make coffee is the most reliable way to become the boat everyone discusses. Music at the dock is usually a private affair: check the volume from the pier rather than from the helm, and use headphones when in doubt. If you must run an engine to charge batteries, do it mid-afternoon and keep it short.
Dock carts, hoses, power pedestals, fish cleaning stations and the water tap all belong to everyone and to no one. Return the cart to the rack rather than the end of your finger pier, and never leave it parked across a gangway where someone will trip in the dark.
If two boats share a pedestal, split the outlets without a discussion and replace the cover. Never unplug a neighbour's shore power to test your own cord; if you genuinely need the outlet, knock and ask. Same with water: a quick "mind if I top up?" costs nothing, and using someone's spigot to wash your whole boat costs you goodwill.
Wash, first, is wake. Idle speed through fairways and no-wake zones is not just courtesy. Your wake lifts boats against their lines, tips drinks off cockpit tables and can slam a hand between hull and fender.
Wash also means soap. Hosing a boat down at the dock sends suds, deck dirt and whatever else was up top straight into the water, and many marinas and harbours restrict it. Rinse with fresh water, use a bucket when you can, and never spray across a neighbour's open hatches or a hatch you can't see. Keep oily bilge water out of the water entirely and use the pump-out and bilge pads instead. Rules differ from place to place, so ask the dockmaster what is allowed before you break out the hose and the brush.
When a blow is forecast, walk the dock. Double your own lines, add a spring line, and check that the boat beside you isn't hanging on one frayed line with the wind pushing it toward your hull. A quiet word now beats a claim later.
Noticing works both ways, though, and privacy counts. Don't step onto another boat, don't lift a cockpit cover to look inside, and don't photograph someone's vessel for your own feed. If something looks wrong, a drifting fender or a bilge pump running every few minutes, take a photo, tell the dockmaster, and knock if the owner is aboard.
Boats forgive bad weather far more easily than they forgive bad manners.
The rules above are easier to follow when you set yourself up well at the start. Give the first week a little attention and the rest of the season looks after itself.
None of this is complicated, and most of it comes down to asking rather than assuming. Be the boat that asks, that returns the cart, that keeps its halyards quiet and its wake small. In a marina, the highest compliment is that nobody noticed you at all.
