  • Page 22: Safety Facilities

    There is no harmonization of obligatory safety equipment across the European Community. You should seek information about national requirements for CE-marked boats.

  • Page 23: Handling, Transporting, Haulout

    When craning, take care that the slings are correctly positioned and are not fouling the propeller, the sail-drive or a fragile sensor. Lifting frames should be wide enough, or fitted with spreaders to avoid exerting excessive lateral pressure on the rubbing band. Avoid letting slings foul the lifelines.
