Overboard Bag List: The Ditch Bag That Leaves the Boat With You
Bag Lists Overboard Bag List
This is an overboard bag — the one bag that leaves the boat with you. It's built to get you found and keep you alive in the water until help arrives. Below is every item at three budgets, with the reason each one is in the bag.
This list is built for one person. Answer five quick questions and the builder sizes it for your people, your climate and how far you have to go.
Water
You can go three weeks without food and three days without water, and you'll be useless long before day three. Carry some, and carry a way to make more. The mistake people make: one bottle and no filter, as if the tap is coming back.

Datrex Emergency Water Packets, 3-Day Supply (18)
Coast Guard-approved water that packs flat and keeps for five years. |
✓ | ✓ | ✓ | $21.95Amazon |
Shelter and warmth
Weather kills faster than hunger. A poncho and a tarp get you out of the rain in ten minutes; a bivvy gets you through a night you didn't plan on. The mistake: packing for the day you leave, not the night you stay out.

SOL Emergency Bivvy with Whistle
A 4.5 oz bivvy is a sleeping bag you can afford to carry and never use. |
✓ | ✓ | ✓ | $28.78Amazon |
First aid
This kit treats what actually happens: cuts, blisters, burns, sprains, upset stomachs. It is not a trauma bay. Know what's in it before you need it. The mistake: a big kit you've never opened.
| Item | Essentials | Solid | Best gear | Buy |
|---|---|---|---|---|
Adventure Medical Kits Ultralight/Watertight .5
Treats what's likely: cuts, blisters, burns, sprains. |
✓ | – | – | $31.95Amazon |

On open water the sun hits you from above and off the water. A burn costs you water you can't spare. |
✓ | ✓ | ✓ | $8.42Amazon |
Bonine Motion Sickness Tablets (16 ct)
Seasickness throws up water you can't spare. Take it before you need it. |
✓ | ✓ | ✓ | $7.31Amazon |

A bigger, organized kit with more of everything, sorted so you can find it fast when your hands are shaking. |
– | – | ✓ | $114.95Amazon |
Signal and navigate
Being found is a plan, not luck. A whistle carries farther than a voice, a mirror reaches an aircraft, a compass works when the phone doesn't. The mistake: counting on a phone with 12% battery and no signal.
| Item | Essentials | Solid | Best gear | Buy |
|---|---|---|---|---|
ACR C-Strobe H2O Water-Activated Strobe
Turns itself on in the water, so rescuers can see you at night even if you can't reach it. |

Best Glide ASE Military Grade Glass Signal Mirror (2 x 3)
Being found is a plan, not luck. |
✓ | ✓ | ✓ | $49.95Amazon |
CACOE Floating Waterproof Phone Pouch (2-Pack)
A dry phone is a second radio near shore. This pouch floats, and you can work the screen through it. |
✓ | ✓ | ✓ | $9.99Amazon |
Ocean Signal rescueME PLB1 Personal Locator Beacon
The smallest beacon there is. No confirmation light, but it clips to a life jacket and you'll never leave it behind. |
✓ | – | – | $399.95Amazon |
Standard Horizon HX890 Floating VHF with GPS
Floats, and the red DSC button sends your GPS position to the Coast Guard and every boat in range. Program your MMSI number first. |
✓ | ✓ | ✓ | $265.00Amazon |
UST JetScream Floating Whistle
A whistle carries farther than your voice and never gets hoarse. This one floats, so clip it to your jacket or a strap and it stays with you even if the bag doesn't. |
✓ | ✓ | ✓ | $10.60Amazon |
ACR ResQLink View RLS Personal Locator Beacon
The return-link light tells you the satellites got your distress call and know where you are. In a raft, that's the difference between waiting and hoping. |
– | ✓ | ✓ | $529.95Amazon |
Garmin inReach Mini 2 Satellite Communicator
Two-way text messages and SOS over satellite, so you can tell rescuers what's wrong and hear back that help is coming. It needs a Garmin subscription; set it up before you need it. |
– | ✓ | ✓ | $299.00Amazon |
Ocean Signal rescueME MOB1 AIS Man Overboard Beacon
Clip it to your life jacket. If you go in, it alerts your own boat and boats nearby on AIS, and it can switch itself on when the jacket inflates. |
– | – | ✓ | $384.95Amazon |
Light and power
Everything is harder in the dark, and dark comes every day. A headlamp keeps both hands free; a power bank keeps the headlamp and the phone alive. The mistake: one flashlight with the batteries it came with.
| Item | Essentials | Solid | Best gear | Buy |
|---|---|---|---|---|
Dorcy Floating Waterproof LED Flashlight
Light after dark is safety, not comfort. |
✓ | ✓ | ✓ | $9.99Amazon |
Sirius Signal C-1003 SOS Distress Light
An electronic flare that comes with an orange day flag and a whistle. Together they meet the Coast Guard distress-signal rules, and nothing in it expires the way pyrotechnic flares do. |
✓ | ✓ | ✓ | $69.99Amazon |
Food
Calories keep you thinking straight. Freeze-dried meals weigh almost nothing; a stove that burns twigs means no fuel to run out of. The mistake: canned food (heavy) or nothing but granola bars (day two is grim).
| Item | Essentials | Solid | Best gear | Buy |
|---|---|---|---|---|
S.O.S. Millennium Emergency Food Bars (9 Bars)
Calories you can eat without cooking if you have to. |
✓ | ✓ | ✓ | $32.99Amazon |
Tools
The things that make everything else in the bag work: a knife, cord, something to write with, a way to fix what breaks. The mistake: a huge knife and nothing else.
| Item | Essentials | Solid | Best gear | Buy |
|---|---|---|---|---|
15-Pc. Emergency Survival Fishing Kit
If one day becomes three, a hook and line turns the water around you into food. |
✓ | ✓ | ✓ | $12.95Amazon |
Spyderco Atlantic Salt Rescue Knife
H1 steel won't rust in salt water, and the blunt tip won't puncture a raft or you. |
✓ | ✓ | ✓ | $118.42Amazon |
Carry it
Dry sacks keep the important stuff dry and let you find things without dumping the pack. The pack itself should fit you, not the other way around. The mistake: a bag that's full on day one.

|---|---|---|---|---|
ACR RapidDitch Express Bag
It floats, it's bright, and it has a handle you can grab on the way over the side. |
