Sailboat Offshore Damage Control Check-list

Request Price  |  length:   |  

In addition to being an industry supporter of the Newport-to-Bermuda Race, McMichael Yacht Yards & Brokers is a sponsor of the upcoming Storm Trysail Hands-on Safety-at-Seminar that provides a range of safety tips and guidelines for sailors of any level. Here is what STC prescribes for damage control equipment for boats going offshore. Even coastal cruisers should have most of these tools.

Damage Control tools and supplies should be stowed in containers so they are available at short notice. Location should be noted on the posted Emergency Chart. Larger items such as timber, spare shroud, drogue, and emergency tiller should also be noted. In the corner photo is a charged power pack drill, rolled lead sheet with pre-drilled perimeter, self- tapping screws with matching nut-driver, and rubber mallet. This hull patching package is stowed together since in an emergency it would be used together, along with Lifecaulk.
