I seem to recall you take your boat out in salt water (seems unlikely there are lots of lakes or navigable rivers in Qatar
).
Salt water usually means you are in BIG water - open ocean and such. So marine grade equipment and planning is definitely in order.
The US Coast Guard website
http://www.uscgboating.org/ has lots of information about boating safety equipment and methods.
At minimum you should have the following:
-Fire extinguisher (rated for extinguishing fuels)
-Flare gun - visual signal devices (orange flag, flat mirrors)
-Life jackets
-Extra towels/blankets (hard to believe, but at night in wind this is important)
-Extra rope - towing strength for rescue or being rescued
- Audible signaling devices - hand held air horn, whistles (ideally attach whistle to each life jacket)
- First-aid medical kit in waterproof container.
For common repairs or troubleshooting:
- Extra spark plugs
- Spark plug wrench/socket (leave this with the boat)
- Tool box kit, screwdrivers, big pliers, cutters, adjustable wrench
- Hex key set (a lot of engine hardware is hex/allen key based)
- Waterproof containers/bags (for putting cell phone or radio in)
- Long nose pliers (for pulling out weeds, rope from jetpump)
- Bilge sponge and or bucket (for extracting water if the bilge pump or battery dies)
- diving mask and snorkel (so you can inspect under boat if necessary)
- 2-3ft length of extra fuel hose and water cooling hose plus hose clamps
- extra fuses
- Zip ties - the nylon tie straps you typically see your hoses tied back with.
What can I say, I like to be prepared.
