7. Today’s Mooring Situation
33 moorings afloat, ??? lost
Chain (various sizes) with concrete blocks of various sizes
All inspected in 07
Need more moorings in spring but mostly in fall

8. Lessons learned from Inspection
Flat mooring blocks are better than any other shape. All top corners should be rounded.
Anchor loop in concrete must be substantial in diameter to allow for abrasion wear.
The chain at the very bottom MUST be protected against abrasion from the concrete. We found moorings with perfect looking 1/2" chain at the top and at the bottom it was corroded to about 1/4". This happened because the galvanizing was abraded off from rubbing on the top of concrete pad and the chain began to corrode galvanically.

9. Lessons learned from Inspection
We should use the largest size hardware at the bottom that can be fitted. All 1/2" chain is heavy and tends to sink the balls partially.
For the minimal cost, the shackles at the top should be replaced every season on all moorings. We found a lot of shackles that still had the paint on the pin handle, but the threads were gone completely.
The divers found most of the plastic tie wraps at the bottom to be broken or missing. They highly recommend an aircraft grade tie wire instead of plastic ties. Plastic ties are fine at the top, where they can be inspected and replaced annually.
A swivel at the bottom is recommended.

16. Nylon mooring system
Cost advantage $300 vs $445 ($76 vs $208)
½” chain breaking strength 18000lbs
1” nylon three strand lbs wet
Both need chafe protection, regular inspection
Nylon versus Chain for shock absorbing
May hobby horse more on a nylon mooring
Will require upgrading of pontoon boat.
Won’t rust, still have steel shackle issues.
Painters should be 1.5 to 2.5 times freeboard maximum!
