I want to measure the load on a chain hook with an inelastic snubber and then with an elastic snubber. Because I have a cat and the snubber is a bridle the hook is at, or very near, the water surface and the load cell will inevitably get soaked. The load cell is not stainless and I imagine the cabling will not react well to immersion. To make any measurements, that are of any value - no need to debate why or for whom they might have merit
) this will take a few hours to set up and measure - so the load cell would be well sodden.
I can measure the load at the 'end' of the 2 snubbers - where they are secured to the yacht (and its nice and dry - I'm not going to do this in the rain!)
The loads tend to be on one side of the bridle or the other (as the cat yaws) so measuring one side should give a (or the) maximum for any gust or snatch which I can then correlate with wind speed and scope (of the chain).
If I place the load cell between the securement point and the snubber will the load I measure be the same as the load at the chain hook - assuming no friction. The inelastic snubber is not really the question - its whether the load on the end of the elastic snubber is the same as the load at the chain hook (10m away). In my naivety I assume they are the same but stand to be corrected.
