The smoke alarms in my apartment building are both ridiculously sensitive and ridiculously loud. They regularly go off even when thereâs no smoke, and I often have to scramble up on top of a chair to reset them because a pot of boiling water is producing steam.here There's Smoke ... There are two main types of smoke alarms used in homes: ionization detectors and photoelectric detectors. Inside the ionization ones thereâs an ionization chamber with two plates and a source of ionizing radiation.
Preventing Running Aground. A pleasure craft is grounded (runs aground) when it gets stuck on the bottom. Never assume that water is deep enough just because you are away from the shore. Also, donât presume that all shallow hazards will be marked by a danger buoy.
Location: sausalito. Posts: 7,256. the best keel anchor ever made was a wing keel. my experience is that when you go aground in mud, you can forget about kedging a wing keel off. other disadvantage was getting the yard to paint the bottom of the keel, since the boat would be sitting on it in the stands.n my mind the advantage of a wing keel is the shallow draft. Since most cruising sailing is done off the wind, the wing will be as fast as the deeper keel version on the same boat. The disadvantage is they are often shaped like a bruce anchor and will be harder to get off in a soft grounding.
