Your fire extinguisher must be Coast Guard approved
________________________________________________________________
How many and what type depends on the type of boat.
Look at Federal Requirements for Recreational Boats
Here's a summary of requirements for vessel type
All motor vessels are required to have a Type B fire extinguisher(s) on board if one or more of the following conditions exist:
So essentially if you have an inboard engine or permanent fuel tanks or enclosed compartments (for any size boat) you need at least one fire extinguisher. See the brochure at the link below. If the boat is 26 feet or over, you may need two or more.
Similarly, if your boat has an outboard motor and meets any of the other requirements in the list above, it too must have at least one B-1 fire extinguisher.
Each state may have additional requirements that may be more strict. Check with your state Boating law administrator.
Boats with outboards less than 26' and without permanent fuel tanks do not require fire extinguishers (unless they carry paying passengers).
Boats 26 - 40' require two B-I type portable extinguishers or one B-II type.
Boats 40 - 65' require at least three B-I type or one B-I type plus one B-II type portable extinguishers.
To clarify the requirements on Class A or Class 1 outboards:
What this means is simply if you have compartments or lockers on your boat, even though it is under 26 feet and has portable fuel tanks mounted in the open, you still must have a fire extinguisher. The only exceptions are completely open boats with no compartments or lockers, and no decks. Live bait wells are not considered compartments or lockers. But if you have a splash well for the outboard, and the tanks are under the splash well, and there is some sort of curtain, a hatch or door closing off the area under the splash well, then that is a compartment and you need a fire extinguisher.
A USCG-approved Type B-I (B-1) fire extinguisher is required on a powered personal watercraft when operating under USCG jurisdiction, because it has an inboard engine, or a fixed fuel tank, or a closed compartment, or all of the above.
Under US Coast Guard regulations, an inboard powerboat or one with permanent fuel tanks, must have at least one USCG approved B-1 extinguisher, if the boat is less than 26 feet long.
A fire on a PWC will most likely involve flammable fuel liquids, so an ABC or BC type extinguisher should be used.
If the PWC is operated on waters within the jurisdiction of the US or Canadian Coast Guard, or any state or territory that has adopted USCG standards for fire extinguishers, it must also be USCG-approved as Class B-I (or "B-1").
The Coast Guard requires that a class B-1 Coast Guard approved portable fire extinguisher in working condition be aboard every PWC

Class B
Usually one or more USCG-approved Class B-I or B-II are required. According to US Coast Guard regulations (46 CFR 25.30): At least one USCG-approved Class B-1 fire extinguisher is required on any powerboat with a permanently installed fuel tank. A UL-listed 5-B:C extinguisher, with 2 pounds of dry chemical, may provide the basis for the extinguisher, but it must ALSO conform to USCG-approvals (proper corrosion protection, labeling, mounting bracket, etc). A 4-pound CO2 extinguisher or 6 quarts foam extinguisher may also be rated for USCG B-1 service. Powerboats over 26 feet may require additional extinguishers, as detailed in the related questions. Up to 26 feet: one B-I extinguisher; Over 26 but under 40 feet: two B-I extinguishers; Over 40 feet but not over 65 feet: three B-I. Note that two B-I extinguishers may be substituted for a B-II extinguisher. NOTE: When a fixed fire extinguisher system is installed in the machinery space(s), it will replace one B-1 type portable extinguisher.
Powerboat, unless it is a small, open, outboard (Class A or Class 1) that otherwise qualifies for exemption. At least one USCG-approved Class B-1 fire extinguisher is required on any powerboat with a permanently installed fuel tank or carrying passengers for hire. A UL-listed 5-B:C extinguisher, with 2 pounds of dry chemical, may provide the basis for the extinguisher, but it must ALSO conform to USCG-approvals (proper corrosion protection, labeling, mounting bracket, etc). A 4-pound CO2 extinguisher or 6 quarts foam extinguisher may also be rated for USCG B-1 service. Powerboats over 26 feet may require additional extinguishers, as detailed in the related questions.
Yes, a bedroom fire could be quickly extinguished if there were a fire extinguisher handy. There is no particular rule that requires an extinguisher in any sleeping area. Check with your local fire code administrators for more ideas about where is the best place to position a fire extinguisher in a residential occupancy.
If that kitchen extinguisher is rated for Class A, B & C, and has a USCG B-1 rating, then yes, it could be used.The four basic classes and what they are used for are as follows:Class A - Solid combustibles that leave an ash residue after being burnedClass B - Gasoline, oils, liquid combustiblesClass C - Electrical firesClass K - Kitchen fire - stove-top or fryer oil cooking fire, for instance, but not for putting out a fire on a Jet-ski.If your ABC or BC extinguisher has no USCG rating on its label and mounting bracket, then it will not be sufficient to meet USCG requirements, even though it may work perfectly well on a fire.
A UL-listed 5-B:C extinguisher, with 2 pounds of dry chemical, may provide the basis for a B-1 extinguisher, but it must ALSO conform to USCG-approvals (proper corrosion protection, labeling, mounting bracket, etc).
