Excerpts from the article:
Quote:
New Hampshire requires registration of "Sunfish" boats. Doesn't the Marine Patrol have the resources to check decal numbers? Quote:
I'd say to always "ship" those fenders while underway (underweigh?), and check your mooring chains. I replaced my BIL's mooring chain and noticed how much corrosion had occurred to the old chain. The following photo shows the very same length of galvanized chain with varying diameters in its length due to the effects of freshwater corrosion. ![]()

For twelve years we kept our sailboat on a mooring in about 16' of water here in West Alton. Every year or two I would have the mooring chain, shackles, swivel, etc. checked by a diver. Consistently, the chain would be in very good condition near the surface, but the further down it went the more corroded it would be. This appears to be what APS is demonstrating with the photo of his mooring chain. Any theories on why the lake water is much more corrosive at 16' than at the surface? Is it a function of depth, or is the water more corrosive near the bottom regardless of depth?

Could it be that lower part of the the chain is resting on the bottom, and therefore constantly being rubbed against it as the boat moves? Wouldn't this, in addition to wearing the chain on it's own, also rub off each new layer of rust making way for a new layer of rust to corrode it further?

I have a neighbor who for many years had a sailboat on a mooring that used a similar underwater float arrangement, and he observed the same corrosive effect on his chain ... after a few years the chain got progressively thinner the further down it went.

Perhaps its a corollary to Murphy's Law. The problem is always located in the hardest spot to reach ??

Siksukr, you're probably partially correct. That, plus the fact that there's more oxygen in the colder water (that's why trout like it better).

I've pulled mooring chains in 6' of water that have gone from 5/16" to 1/8" in the course of 3 years. No wearing or rubbing on anything. Just corrosion from ?. No dissimilar metals or anything. Just have to keep checking them.

Stainless steel chain solves the problem.

I've lost my sanity, do you think they found it?

This thread makes me think that I should write our name and number on everything outside!
![]() It is possible that is our stern light. We lost one overnight after the Wolfeboro fireworks. Didn’t notice it was missing until the following Friday night when we were trying to head to the island after dark. As it was replaced it the next morning, we do not need it back. I had no idea that a stern light would float. Next time I will call MP, especially given how many times I have called to report found stuff myself. |

My friends got a dock section once that we held onto for a year and added in the next year. A couple years back, when they were selling, they didnt set up the dock but a piece on stilts ground just past their ramp so we used that all summer. The new owner never took it in though and it floated away over the winter.

Is there any chance my little sailboat paddle found its' way to the state's lost & found? Lost on a windy afternoon, last June, west of Mark Island - a three foot, wood paddle, painted white w/ a single red stripe, and "HELP" in 3" high letters on the other side.

Just watched the rerun of Dirty Jobs replacing moorings. It made me want to take a swim. Of all the things I've lost its my mind I miss the most. ![]() |

It must have to do with the local currents but I have found three fenders over the years while having lunch on Garwoods deck. They just seem to collect there. Jumping the rail and snatching a fender may look cheap but after shelling out three bucks for a Tuckerman's Pale Ale I'm looking for a bargan!
As for chains, I have a 1/2 inch chain on the bottom to help compensate for the removal of the passive film that rust provides. This is attached to a 3/8 chain going up to the moorings via swivles. The 3/8 chain gets rotated, top to bottom, every three years or so and replaced as necessary. As for Dave's "dirty job"... As a professional diver he could do a lot worse than ploping moorings in shallow water that is so clean you can drink it! Misy Blue. |

I just happened on this thread. I lost a kayak paddle this summer on July 23rd. I can't remember the brand, but it had orangle paddles with a black shaft. I have since replaced it, and am not looking to get it back. We think that maybe a mischievous person took it. It would make me feel better if maybe it just floated away... Was wondering if the paddle Gatto Nero found might have been mine.
