Any sailboat or recreational vessel of any kind needs a ditch bag. Never assume, even when you have communication gear, that rescue will come before you would need the things typically carried in an abandon ship bag.
Although most liferafts are equipped with some basic survival equipment, also never assume that it has everything you need or may want. Life rafts typically have only minimal gear, because of space and weight limitations, and you can’t unpack them to check or add more.
The only way to increase your chances for rescue and survival until rescue is to have a well-stocked ditch bag.
The Bag Itself
You could make your own, but commercially available abandon ship bags are relatively inexpensive and usually the best way to ensure the bag has all the right characteristics:
- Positive flotation. You might drop it while scrambling to the liferaft or dinghy. Most commercial models such as the one shown have flexible foam sewn into the sides, top, and bottom to provide both flotation and padding. Air trapped in sealed plastic gear bags inside also adds flotation.
- Water resistant. It need not be waterproof (expensive) because critical items inside can be put in sealed pouches, but you don’t want it to immediately fill with water and possibly sink.
- Visibility. Most are yellow or international orange. You can improve nighttime visibility by attaching reflector strips, which will shine brightly in a flashlight beam in case you lose the bag overboard, and which may aid in a nighttime rescue.
- Sufficient size. Be sure your bag is large enough to hold everything you plan to include. If you have many crew, you’ll need a lot of space just for water.
- Sturdy carry and lanyard straps. Obviously you’ll need to be able to carry it easily off the boat, and in storm conditions you should also be able to easily tie or clip a strong lanyard to the straps before transporting it off the boat.
- Clearly labeled and stowed. Keep the ditch bag it a handy place below decks but where everyone can see it.
Considering a multitude of abandon ship scenarios, you will want to include both rescue and survival items along with optional personal or other items.
- Functioning, registered 406 EPIRB (emergency position-indicating rescue beacon) to inform rescuers of your need and location
- Handheld VHF radio (waterproof or in sealed pouch, with extra batteries)
- Selection of flares (parachute and handheld) and smoke signals
- Strobe light (may be present in inflatable PFD); combination with flashlight ideal
- Whistle (may be present in inflatable PFD)
- Signal mirror
- Water (individually sealed emergency water packets better than a jug)—as much as you have room for.
- Water filter if not in salt water
- Emergency food rations (commercially available sealed high-calorie bars formulated to decrease thirst) plus can opener if canned food
- Essential personal prescribed medications
- First aid kit
- Solar still (inexpensive) or hand-operated desalinating watermaker (expensive) if offshore
- Patch kit for inflatable dinghy or liferaft (or emergency clamps)
- Knife (preferably with rounded rather than pointed tip if in a raft)
- Rope can keep the crew together should a lifeboat not be available
Other Items (depending on space and needs)
- Handheld GPS (to communicate position by VHF or cell phone)
- Solar blanket (in cold climates)
- Simple fishing gear (line, jigs, hooks)
- Sunscreen (in tropics—liferaft canopies can tear off)
- Paper and pen in ziplock bag
- Spare prescription glasses, sunglasses (polarized to reduce glare)
- Small pair of binoculars (to confirm a boat or plane spotting before using flares)
Check your abandon ship bag at the beginning of every season and before a long voyage. Look for expired flares and any tears in water or food packets. (Mice may attack in the off-season!) Replace batteries.
Remember the old salt’s saying: You step up into the liferaft when abandoning ship. In other words, stay on the boat unless it is really, truly sinking—many boats have been found floating after a storm, abandoned by panicked sailors. You’re safer on your boat, even half full of water, than in a liferaft or dinghy in open water, and it’s much easier for rescuers to find you.
Finally, when going offshore, talk with all crew about their roles in all types of emergencies. Talk about who should grab what if it is necessary to abandon ship. While one or two launch the liferaft and someone else fetches the ditch bag, others can grab additional water jugs, more flares, the ship’s larger first aid kit, a prepared pouch of the ship’s documents and passports, etc.
