Dock protection: the whole tie-up in one box

Every transient dock is the same trap: bare lumber at a height you didn't choose, a tide or wake rolling through, and a line of boats behind you at the fuel pump. The Greenfield Dock Kit answers with one box — two fenders, two stretch lines, and no-knot Rope Locks — that rigs in seconds and stows when you leave.

What's in a dock protection kit?

Four components, chosen to work as one system:

• Two cylindrical PVC fenders — made in the USA — in 4.5-inch or 5.5-inch diameter. Call them boat bumpers for docking if you like; either way, they take the dock's hits so the hull doesn't, and the damage they prevent is specific: scratches, gel-coat chips, fiberglass repairs.
• Fender lines to hang them from a rail or cleat, with the height set by the Rope Locks.
• Dock Buddy bungee dock lines (2-pack) — hollow-braid polypropylene over a bungee core, foam grips, sliding eye adjusters, 1,100 lb breaking strength. They float if dropped, which matters at a fuel dock where a sunk line finds the prop. And the pedigree is real: Dock Buddy was the world's first bungee dock line, introduced in the 1990s.
• Rope Locks — patented, USA-made feed-and-lock clamps, strength-tested to 1,600 lb. They replace every knot in the operation.

The kit carries a 2-year manufacturer warranty, from the family-owned company that has been holding America's boats since 1959.

How do Rope Locks work?

Feed the rope through and it locks — that's the entire skill requirement. The same device does two jobs:

Fender height. Hang the fender line over a rail or cleat, feed it through the Rope Lock, slide the fender to where it meets the dock face, and lock. Re-docking at a higher or lower dock later means feed and re-lock — seconds, not re-tying a fender hitch.

Dock lines. Loop the Dock Buddy over the cleat, feed the tail through, lock. Removal is just as fast, which is the whole point when boats are waiting behind you.

For anyone eyeing a plastic clamp with suspicion: Rope Locks are strength-tested to 1,600 pounds — more than the 1,100-pound line they grip. They're for everyone whose cleat hitch is more of a suggestion, and for everyone else who'd rather be done in five seconds.

What size boat fenders do I need?

Two sizes, one decision: 4.5-inch fenders (the Small kit) for PWC, jet skis, and small boats; 5.5-inch fenders (the Large kit) for mid-size boats up to about 25 feet. The industry rule of thumb runs about an inch of cylindrical-fender diameter per 4 to 5 feet of boat, which lands in the same territory. Between sizes? Take the Large — a bigger fender never scratched a smaller boat.

Hang height matters as much as diameter: a fender rides just above the waterline, so it meets the dock before your hull does. The two classic ways to waste a fender are hanging it too high (decorative) and letting it drag in the water (a small sea anchor). The Rope Lock exists so fixing either takes five seconds.

How do you rig it at the dock?

Fenders first, lines second — everything locks, nothing ties.

1. Size up the dock on approach

   Fixed or floating? Flat face or pilings? Spot where the dock edge will meet your hull — that's your fender position: one at the widest point of the hull, the other where contact happens fore or aft.

2. Set fender height before you're alongside

   Hang each fender line, feed it through a Rope Lock, slide the fender to just above the waterline, and lock. Vertical against a flat dock edge; horizontal works against pilings.

3. Come alongside and loop the Dock Buddy

   Drop the line's eye over the dock cleat — the sliding adjusters size the loop. Fumble one into the water? It floats; fish it out and carry on.

4. Feed and lock — no knots

   Feed the tail through a Rope Lock and lock it. Snug is right: the bungee core keeps tension as wakes and tide move the boat, so don't leave a slack belly in the line.

5. Repeat at the second cleat and step off

   Two fenders set, two stretch lines locked — the boat rides against padding, not dock lumber.

6. Leaving: release, lift, stow

   Rope Locks let go as fast as they set, and the kit goes back in its compartment. Nothing stays behind on the dock.

Where the kit earns its keep

Day docking is the job: marina stops, fuel docks, pump-out stations, launch ramps, restaurant docks — anywhere you tie up for minutes to hours at a dock that isn't yours and has no padding. The kit is the underway answer: light, stowable, rigged in seconds, gone when you are.

Two fenders is honest coverage for exactly that duty — small craft, and alongside tie-ups where one side touches. A boat living full-time in a slip deserves more: the slip-outfitting rule of thumb is one fender per 10 feet of waterline per side, minimum three, and that's dedicated slip gear, not a grab-and-go box. For a bigger boat at a rough transient dock, a second kit is the straightforward fix.

Is this an anchor kit?

No — the Dock Kit protects your boat at the dock, and there is no anchor in the box. If anchoring is the job, start with the boat anchor kit guide. And the name worth untangling: Dock Buddy is the bungee dock line inside this kit; Anchor Buddy is Greenfield's stretch anchor line for holding a boat off a beach — that one has its own guide, Anchor Buddy: what it is (and what it isn't). Same family, different ends of the boat day.

Already own fenders? Then you want lines only: Stretch 'n Slide, the seven-loop bungee dock line, is the cheaper answer — the bungee dock lines guide covers it, rafting included.
