I need to combine these metals in an anchor rode rig and think that probably some corrosive action or worse may result. What think guys?
The above-water concern would be much less as you say--- I went back and added that to my previous post.* But it will all depend on the environment.* If the components are getting dowsed with water regularly*and have salt buildups on them--- which is the issue with floatplanes--- the problem can be accelerated.Delfin wrote:
Marin, I can see that happening on a mooring chain permanently in the water but do you think it is an issue when anchoring?* I understand the theory, but having used stainless steel siezing wire on shackles for 20 years without sign of degradation I wonder if this is a real concern.
Eric--- I believe for catenary to be significantly effective in an anchor rode, the whole rode needs to sag, thus lowering the angle of pull.* All-chain rode does this automatically.* But while putting a weight just a few inches away from an anchor shank should help hold the end of the anchor shank down, I don't think it will affect the catenary in the rode very much or at all.* What you're doing is adding weight to the anchor itself (albeit a few inches away from the anchor).* If you actually want to increase the catenary and lower the angle of pull on the anchor, I think the weight needs to be somewhere in the middle of the rode beween the anchor and the boat.nomadwilly wrote:
I would think this would cause a maximum catenary effect to enhance anchor performance.
No, I don't disagree with that at all.* Which is why I think your weight right next to the end of the anchor shank will help it assume a better position to dig in and set.nomadwilly wrote:
*And we've always disagreed about this Marin but I think the closer the weight is to the end of the anchor shank the more good it will do and keeping the shank down low keeps the flukes or fluke pointed down.

I suspect that doing so would be pretty easy for an engineer schooled in the use of the appropriate computer application.* Ever see what they can do with Computational Fluid Dynamics?* I have, and it's pretty staggering.nomadwilly wrote:
you could do this w a computer you could do the whole anchor test w a computer.
