The issue of the LifeSling not being accepted as a throwable device came up in Trawlers and Trawlering last Fall/winter. Several members of the CG Aux (or equivilant in Canada) said that it was not accepted at that time. I questioned this, because in my opinon it is a lot better than a life ring:
From: CANADA SHIPPING ACT
Small Vessel Regulations
CRC, Vol. XVII, c. 1487
"Pleasure Craft over 6 m but not over 8 m in Length
16.03 (1) Subject to sections 16.2 and 16.3, every pleasure craft over 6 m but not over 8 m in length shall carry personal protection equipment, boat safety equipment, distress equipment and navigation equipment in accordance with subsections (2) to (5).
(2) Personal protection equipment shall consist of
(a) subject to section 16.08, one personal flotation device or lifejacket of appropriate size for each person on board;
(b) either:
(i) one buoyant heaving line of not less than 15 m in length, or
(ii) one lifebuoy with an outside diameter of 610 mm or 762 mm attached to a buoyant line of not less than 15 m in length; and
(c) a reboarding device, if the freeboard of the pleasure craft exceeds 0.5
(From Definitions section: "reboarding device", in respect of a small vessel, means a ladder, lifting harness or other apparatus that does not include any part of the vessel's propulsion unit and that assists persons in gaining access to the vessel from the water. )
Currently in the Canadian Transport Fishing vessel brochure, they show an item similar to the LifeSling.
The 610 mm outside is 24" and the 720mm outside is 28.3 inches--still difficult to get "into".
I am not aware of anyone being cited for not having a lifering. We had Canadian CG aboard our vessels for social functions a number of times, and had a horseshoe bouy and a life sling--never commented on, so I suspect it is not enforced--if it is really a requirement--but it appears to be on the books...
