Mooring Components:

  • 6' pickup buoy

  • 5/8" 3-strand nylon pendant w/ thimble

  • 5/8" shackle w/ SS wire

  • Polyform A-3 mooring ball

  • 1/2" Polyform shackle w/ SS wire

  • 5/8" eye-eye swivel - 7/16" remaining

  • 1/2" shackle w/ zip tie - 7/16" remaining

  • 3/8" chain, 15' length - 1/4" remaining but w/ no significant corrosion, too long for top chain

  • 1/2" shackle w/ zip tie

  • 1/2" chain, 6' length - good condition but far too short to be effective bottom chain

  • 5/8" shackle w/ SS wire - 1/2" remaining, heavily corroded

  • 3/4" shackle w/ SS wire  - 1/2" remaining, heavily corroded

  • ~200lb? mushroom anchor w/ 7/8" eye - completely buried, weight is a guess

Mooring Maintenance — 6/20/20

Replaced the mid-chain 3/8" shackle with a 1/2" shackle in good condition (reused from another RSYC mooring).

Mooring Inspection — 5/6/20

This mooring is in good shape overall, with some worn components but everything in good/fair condition.

The chain rode uses a 3/8" shackle which is not recommended for use in a boat mooring. 3/8" shackles have half the WLL of chain, so a 3/8" chain rode should use 1/2" shackles/swivels so the WLL matches.

This is the only RSYC mooring I found that's currently using some 1/2" chain, but unfortunately it only has 6' length when it should have ~20' (1.5x the seasonal max depth), so the short length is still largely ineffective in terms of catenary effect / preventing shock loading.

When the current 3/8" chain rode wears out, recommend adding 21' of 1/2" chain (27' total) with 6' of 3/8" top chain.

Recommend replacing the 3/8" shackle with a 1/2" shackle.

Cursory Mooring Ball Inspection — 11/19/19

This mooring has two separate 3-strand nylon pendants set up as a bridle, but are attached to opposite ends of the chain swivel which makes no sense (one pendant can swivel, one can't). The thimbles are rusting through to the point where they will no longer protect the line. The pickup buoy line is brittle & very thin.

Recommend replacing the pendants/bridle, adding a shackle at the top of the swivel to attach the new pendant, replacing the swivel, & replacing the failing mooring ball chain with a Polyform buoy shackle.
