Hurricane or Windstorm Preparation

Best Practices Guideline

The Marine Community knows, boats suffer less damage during Heavy Weather or Windstorms if they are properly prepared using the suggested methods and recommendations below.

BOATS KEPT IN WATER FOR HURRICANES

  • Lines should be set in a spider web formation. Use the minimum size and number of lines listed.
  • Anchors or ground tackle should be set to keep hulls away from solid objects.
  • Strip all loose gear, sails, canvas, Bimini tops, dodgers, awnings, enclosures, Isinglas®, cushions, booms, poles, covers and similar items and valuables and valuable equipment including detachable electronics be removed and stowed in a secure location.
  • Ports, hatches and other above-the-waterline openings into the hull should be sealed with Duct tape to reduce or prevent water ingress from wind-driven rain and spray.
  • Duct tape covers over non-removeable electronics.
  • Scuppers & drains free and clear to prevent water accumulation.

BOATS NOT KEPT IN WATER FOR HURRICANES

  • Strip all loose gear, sails, canvas, Bimini tops, dodgers, awnings, enclosures, Isinglas®, cushions, outriggers, booms, poles, covers and similar items and valuables and valuable equipment including detachable electronics be removed and stowed in a secure location.
  • Ports, hatches and other above-the-waterline openings into the hull should be sealed with Duct tape to reduce or prevent water ingress from wind-driven rain and spray.
  • Duct tape covers over non-removeable electronics.
  • Scuppers & drains free and clear to prevent water accumulation.
  • Garboard/Bilge drain plugs removed. Remember to reinstall before launch!
  • If possible, store above the anticipated Storm Surge.
  • Straps, when required, should be placed midships. A minimum of two (2) straps are required or four (4) tie-down lines.

Layup methods by preference

  1. Stored in a hurricane-rated building.
  2. Stored on a rack, strapped securely.
  3. Stored in a cradle, strapped securely to padeyes or augers.
  4. Stored in a Hurricane Pit, strapped securely to padeyes or augers.
  5. Stored on Jackstands or Jackscrews, chained together with chains welded, safety wired or otherwise secured to prevent removal of chains.
    Jackstands not on concrete should be set on minimum 3/4-inch (19mm) Plywood pads.

Boats on Jackstands should be strapped securely to padeyes or augers.

  • Duct tape covers over non-removeable electronics.
  • Scuppers & drains free and clear to prevent water accumulation.
  • Garboard/Bilge drain plugs removed. Remember to reinstall before launch!
  • Lift outboard motors
  • Strap or otherwise secure your boat to the lifting apparatus.
  • Secure your boat from swinging or drifting away.
  • Use fenders where your boat could contact pilings, seawalls, decks or other objects.
