🪼 Sea Nettle Forecast — Chesapeake Bay

NOAA probability-of-encounter maps for Chrysaora chesapeakei — the Chesapeake Bay sea nettle. Most abundant in middle Bay tributaries where salinity runs 10–20 ppt. Updated daily from NOAA NCCOS model runs.

Today (Day 1)
Sea nettle forecast — today
Tomorrow (Day 2)
Sea nettle forecast — tomorrow

What this means from Shady Side: Sea nettles are most common June through September when water temperatures exceed 78°F and salinity is in the 10–20 ppt range. The middle Bay tributaries — West River, South River, Rhode River — are prime nettle habitat. Higher probability doesn't mean guaranteed stings, but plan accordingly for swimming and crabbing.

Practical notes: Nettles concentrate near the surface in calm water and along current lines. Windy days and moving water can disperse them. Early season (June) is usually lighter; peak is July–August. Vinegar helps with stings — not freshwater.

Live Vessel Traffic

Commercial movement, bridge approaches, and why traffic matters to small boats

Real-Time Ship Traffic — Middle Chesapeake

Why Traffic Matters to Small BoatsOpen for the full small-boat traffic explainer.

Big commercial vessels do not stop quickly, cannot turn on a dime, and often have major blind spots ahead of the bow and along both sides. Even when they look far away, their speed, displacement, and wake can create real risk for a small boat, skiff, or center console.

Wherever you boat, pay extra attention in these four traffic environments:

Bridge & Causeway Approaches

Current, structure, narrow spans, and converging boat traffic compress decision time. Avoid lingering in marked navigation spans and give larger vessels the room they need to stay in the channel.

Harbor, Inlet & Marina Mouths

Ferries, charter boats, fuel dock traffic, sailboats, paddlers, and local traffic often stack into the same choke point. Expect crossing traffic, changing speeds, and limited sight lines.

Marked Channel Crossings

When you need to cross a shipping or ferry route, do it decisively, cross at as close to a right angle as practical, and spend as little time in the lane as possible. Never assume the bigger vessel can or will move for you.

Working-Waterfront Routes

Tugs, barges, ferries, pilot boats, fishing boats, and service craft often follow predictable deep-water or dredged routes close to recreational water. Build the traffic picture early, monitor VHF where appropriate, and avoid getting pinned between wake, current, shoals, and hard structure.

⚓ Boater's Cheat Sheet

The basics every operator should know before leaving the dock. Based on USCG Navigation Rules and COLREGS. Not a substitute for a boating safety course — but a quick-reference for the rules that matter most on the Chesapeake.

🧭 Navigation Rules of the Road
Meeting Head-On

Both boats steer to starboard (right) and pass port-to-port. This is the default for two power vessels approaching each other.

Crossing Situations

The boat on your right is the stand-on vessel — it holds course and speed. You are the give-way vessel and must pass behind it.

Overtaking (Passing)

The vessel being passed always has the right of way. The passing vessel must stay clear and bear full responsibility.

Power vs. Sail

Power-driven vessels must yield to sailing vessels — unless the sailboat is overtaking. Power also yields to vessels not under command, restricted in ability to maneuver, and vessels engaged in fishing.

Safe Speed

Operate at a speed that allows you to take proper action to avoid collision. Comply with no-wake zones — fully off plane, minimal wake. Conditions, visibility, traffic density, and your stopping distance all factor in.

📯 Sound Signals

Short blast ≈ 1 second. Prolonged blast ≈ 4–6 seconds. Required in restricted visibility and during maneuvering situations.

1 Short Blast

I intend to alter course to starboard (pass on your port side).

● ●
2 Short Blasts

I intend to alter course to port (pass on your starboard side).

● ● ● ● ●
5+ Short Blasts

Danger signal — I do not understand your intentions or disagree with your maneuver.

━━━
1 Prolonged Blast

Warning signal — approaching a bend, leaving a dock, or restricted visibility.

🛟 Essential Safety Equipment (USCG Requirements)
Life Jackets (PFDs)

One USCG-approved PFD for each person on board. Must be accessible — not buried in a locker. Properly sized. Children under 13 must wear them.

Throwable Device

Type IV throwable — buoyant cushion or ring buoy. Required on boats 16 feet and over. Must be immediately available, not stowed.

Sound-Producing Device

Whistle or horn. Required on all vessels. Boats 39.4 feet and over need both a whistle and a bell.

Fire Extinguisher

Marine-grade, USCG-approved. Required on boats with enclosed engine compartments, fuel tanks, or enclosed living spaces. Check expiration and charge.

Visual Distress Signals

Required on coastal waters for boats 16 feet and over. Three day signals and three night signals (flares), or a single USCG-approved day/night electronic signal.

Navigation Lights

Required from sunset to sunrise and in restricted visibility. Red (port), green (starboard), white stern, and masthead lights per vessel type.

📖 Key Definitions
Stand-on VesselHolds course and speed. Has right of way.
Give-way VesselMust take early, substantial action to avoid.
StarboardRight side of the vessel (green light).
PortLeft side of the vessel (red light).
WakeWaves produced by a moving vessel. You are responsible for your wake.
AbeamAt right angles to the centerline of your boat.
DraftDepth of water a vessel needs to float.
VHF Ch. 16Emergency and hailing frequency. Monitor at all times.
🚢 Vessel Types to Know
🚢 CargoDeep draft, limited maneuverability, large wake. Cannot stop or turn quickly.
⛽ TankerSecurity zones may apply. Give wide berth at all times.
🚤 Tug & BargeBarge may be far behind the tug on cable. Never pass between them.
⛴️ PassengerTour boats and ferries. Frequent routes, significant wake.
⛵ SailingHas right of way over power (usually). Race fleets can be dense.
🛥️ WorkboatWatermen know the water better than you. Stay clear.
