Onboard security is a matter for everyone. Standard equipment onboard should include a rescue block and tackle to enable even people who are weak or weakened through stress to haul someone out of the water. With a 4 to 1 purchase, cleat and two carabiners to hook into a life harness, a woman would manage to pull her heavily built husband out of the water. The block and tackle has a 33m rope with breaking load up to 2300 DAN.
