Good point re using CO alarm, John. Canadian regulations state that you must have an extinguisher in every sleeping quarter, cooking area and engine room. So on the 33, that makes quarter berth, engine, galley and V-berth, although I dare say one at the nav. table could serve the first three areas. Don't know what coast guard would think of that in an inspection, though. Any surveyors out there that would know?
No, not exactly.... from Transport Canada Minimum Safety Requirements
Sail and Power Boats over 9 m and up to 12 m (29’6” – 39’4”)
13. One (1) 10BC fire extinguisher if equipped with a motor
14. One (1) 10BC fire extinguisher if equipped with a fuel-burning cooking, heating or refrigerating appliance
Sail and Power Boats over 12 m and up to 24 m (39’4” – 78’9”)
13. One (1) 10BC fire extinguisher at all of the following locations:
at each access to any space where a fuel-burning cooking, heating or refrigerating appliance is fitted;
at the entrance to any accommodation space; and at the entrance to the machinery space.
14. One (1) axe
15. Two (2) buckets of at least 10 L each
So, on the 33 the automatic extinguisher in the engine compartment serves as 1, and 1 other in the cooking area meets regulations. That doesn't mean you shouldn't have more as 1 may not be sufficient to put out a fire if it spreads.
