Seasonal Dock Care: Preparing for Hurricanes and High Tides

Water looks peaceful until it does not. One windy afternoon, one storm line on the radar, and the calm turns pushy. If you own a dock, seasonal prep is less about panic and more about small routines that keep structure, hardware, and boats where they belong. Let’s slow it down and set up a plan you can actually follow.

Start with a simple inspection

Walk the dock slowly. Bring a marker and your phone.

• Note loose boards, soft spots, and any fastener that sits proud.
  
  
• Check cleats, ladders, hinges, and pile guides for play.
  
  
• Look at fenders and rub rails. If they are chalky or torn, replace them.
  
  
• Photograph everything, even the stuff that looks fine. Those “before” photos help later.
  
  

If you find one problem, assume there are two. Not always, but often enough to be useful.

Hardware and anchoring matter most

Storms do not politely test the center of a deck. They pull on the edges and joints.

• Use 316 stainless where possible. Galvanized works, but salt and time win eventually.
  
  
• Tighten cleat bolts with backing plates, not just washers.
  
  
• Inspect chains, lines, and shackles for rust or abrasion. Replace early rather than late.
  
  
• For floating docks, confirm pile guide rollers spin freely and have room to ride higher water. Add blocking to keep the dock from wedging under the cap during big surge.
  
  
• For fixed docks, check batter piles, cross-bracing, and all connections to the stringers.
  
  

Electrical and water lines

Turn the breaker off before storms. Sounds obvious, but it is easy to forget in the rush. Elevate cords, secure junction boxes, and add drip loops. Water lines should have accessible shutoffs and flexible sections where the dock moves. Label valves so a neighbor can help if you are away.

Trim what can hit you later

Branches over the fairway or drooping near the gangway become hammers in strong wind. Trim back with care. Bag the debris right away so it does not blow back into the water when the first squall hits.

Build a storm setup you repeat

You do not need a perfect plan. You need the same plan every time.

• Remove loose gear: chairs, cushions, hoses, small tables, grills.
  
  
• Add spring lines and chafe protection at fairleads.
  
  
• Lower Bimini tops and secure covers or remove them.
  
  
• Raise lifts to manufacturer limits, then add safety stops and tie the bow and stern to pilings to reduce sway.
  
  
• If the forecast calls for surge, move PWCs and small craft to a safer spot inland.
  
  

Write this on one page, laminate it, and keep it in a dock box. When weather ramps up, your brain will appreciate the checklist.

High tides and king tides

Not every risk is a named storm. High tides creep. They test freeboard and the small places water sneaks.

• Check that gangways can ride higher water without binding.
  
  
• Add anti-submersion measures for electrical pedestals and outlets.
  
  
• Use taller fenders or foam blocks to keep hulls off the face of the dock when wake stacks on top of tide.
  
  
• If flooded, resist the urge to wade around. Hidden fasteners and live circuits are real hazards.
  
  

After the blow

Go slow. Document first, fix second.

• Take wide photos, then close ups of damage, water lines, and hardware failure points.
  
  
• Look under the deck if you can. Joist hangers and bolts tell the truth about loads.
  
  
• Replace sacrificial anodes, cracked rollers, and any line that looks “almost fine.”
  
  
• If anything shifted, re-square the layout and re-tension lines before normal use.
  
  

Maintenance rhythm that actually works

Storm prep is easier when the baseline is healthy.

• Rinse hardware and floats with fresh water after busy weekends.
  
  
• Tighten a few bolts every month, not all at once in October.
  
  
• Keep a small kit in the dock box: spare shackles, line, chafe guards, cleat bolts, silicone spray for rollers, dielectric grease for terminals.
  
  
• Schedule one short deep check each season. Put it on a calendar so it happens.
  
  

A quick checklist you can copy

• Inspect deck, fasteners, cleats, ladders, pile guides
  
  
• Verify electrical shutoffs and label valves
  
  
• Trim branches over water and walkways
  
  
• Stage extra lines, chafe gear, and fenders
  
  
• Remove loose items before any watch or warning
  
  
• Add spring lines and secure lifts or relocate small craft
  
  
• Photograph before and after for records and insurance
  
  

A quiet closing thought. Preparing a dock for hurricanes and high tides is not about eliminating risk. It is about stacking small advantages. Better hardware. Cleaner lines. Clearer routines. Do those simple things on calm days and the rough days become manageable. The water will still push, of course. Your dock will be ready to ride with it.
