The first time you step onto a boat, the excitement can make you forget there's more than just waves and wind at play.

Ships carry their own traditions, rules, and unspoken etiquette—some practical, some rooted in superstition.

Ignoring them isn't just disrespectful; it can lead to accidents or awkward situations. Understanding these 13 taboos ensures smooth sailing for everyone onboard.

1. Never Step on the Threshold First

On many boats, stepping onto the deck without acknowledging the crew can be seen as careless. It's not just about manners—ships have moving decks, and a misstep could lead to a fall.

Practical tips:

1. Always pause at the entrance and look around before stepping aboard.

2. Follow crew instructions for where to place your feet first.

3. Keep your balance in mind, especially when the vessel rocks.

Even experienced travelers can trip if they ignore this simple step, so make it a habit to be mindful right when you board.

2. Avoid Pointing at Equipment

Pointing at ropes, sails, or navigation instruments is considered bad luck on some ships. Beyond superstition, it's also a safety concern—gesturing near moving equipment can distract the crew.

Practical tips:

1. Use verbal cues instead of pointing when asking about gear.

2. Keep hands away from ropes and rigging unless instructed.

3. Observe first before reaching out or indicating anything.

This small adjustment prevents both misunderstandings and potential hazards.

3. Don't Wear Green on Board

Green clothing has long been linked to sea superstitions about bad luck. While modern sailors may laugh at it, the tradition persists in some circles, especially on smaller vessels.

Practical tips:

1. Opt for neutral or bright colors that improve visibility.

2. Reserve green clothing for land-based activities.

3. Check with the captain if uncertain about local customs.

Even if it seems silly, avoiding green can help you blend in and show respect for the vessel's traditions.

4. Keep Shoes Clean

Boat decks are often slippery or delicate. Dirty shoes not only damage surfaces but also create hazards for everyone.

Practical tips:

1. Bring a separate pair of deck shoes or non-marking sneakers.

2. Wipe feet before stepping onto sensitive areas.

3. Avoid high heels or heavy-soled shoes that could scuff floors.

A little attention to footwear ensures safety and maintains the ship's upkeep.

5. Don't Whistle

Whistling on a ship is traditionally linked to summoning strong winds or storms. While it may feel harmless, crew members often discourage it to avoid distraction or panic.

Practical tips:

1. Keep music and sound low when indoors on deck.

2. Avoid loud whistles or calls near the helm.

3. Use hand signals if you need attention from crew.

This superstition actually helps maintain focus, especially during rough weather.

6. Avoid Sitting on Railings

Leaning or sitting on the railing may look fun, but it's risky. The deck can tilt suddenly, and a fall overboard is a real danger.

Practical tips:

1. Stand behind safety lines or handrails.

2. Always hold onto a stable surface if the boat rocks.

3. Save photos for safe spots rather than the edge.

Even small precautions prevent major accidents.

7. Don't Name the Ship

Some sailors believe saying the ship's name aloud invites bad luck, especially before a voyage. It's an old tradition that still influences maritime culture today.

Practical tips:

1. Refer to it indirectly, like “this vessel,” when onboard.

2. Respect crew habits regarding naming rituals.

3. Focus conversation on practical matters rather than superstition.

Following this keeps you aligned with longstanding customs without awkward moments.

8. Avoid Crossed Knives

Leaving knives crossed on a table or deck is considered unlucky and potentially unsafe. It can also signal conflict in some maritime traditions.

Practical tips:

1. Lay utensils neatly when dining onboard.

2. Store sharp objects securely after use.

3. Teach others, especially children, to follow this habit.

A simple change in placement keeps everyone safe and comfortable.

9. Don't Bring the Wrong Gifts

Offering the wrong type of gift, like a scissors or a clock, can be seen as inviting bad fortune. Thoughtful small tokens like baked treats or coffee are safe choices.

Practical tips:

1. Ask crew for suggestions if you want to bring something.

2. Avoid sharp or potentially hazardous gifts.

3. Consider items that show appreciation without superstition.

It's a small gesture that builds goodwill onboard.

10. Keep Decks Tidy

Cluttered decks aren't just unsightly—they're unsafe. Loose ropes, shoes, or bags can cause trips or block emergency paths.

Practical tips:

1. Stow personal items in designated lockers.

2. Coil ropes properly if handling them.

3. Encourage fellow passengers to keep their space neat.

Tidy decks make everyone's voyage safer and more comfortable.

11. Respect the Helm

The wheel and controls are off-limits to passengers. Interfering can disrupt navigation and put lives at risk.

Practical tips:

1. Observe the helm from a safe distance.

2. Ask before touching or learning about controls.

3. Offer help with non-critical tasks if crew allows.

Keeping clear ensures smooth sailing and builds trust with the crew.

12. Avoid Certain Words

Words linked to storms or bad luck, like “sink” or “storm,” are often avoided at sea. Speaking positively keeps morale high.

Practical tips:

1. Use neutral or positive language in conversation onboard.

2. Replace risky words with alternatives when joking.

3. Pay attention to crew reactions and adjust speech accordingly.

Even playful awareness shows respect for maritime culture.

13. Never Forget Safety Gear

Ignoring life jackets or emergency procedures is a serious breach of shipboard etiquette and safety.

Practical tips:

1. Always locate your life jacket as soon as you board.

2. Attend safety briefings and follow instructions carefully.

3. Check that personal flotation devices fit properly before departure.

Preparedness keeps everyone secure and avoids panic in emergencies.

Ships operate in unique environments where respect, attention, and awareness matter as much as skill. Following these 13 taboos isn't just about superstition—it's about safety, courtesy, and blending into life at sea. When you follow these practices, you sail not just with confidence but with a deeper appreciation for maritime life, making every voyage smoother and more enjoyable.
