Hi Rich- Yes I noticed that beauty on your previous post... It is solid, while the Mantus is bolted together. Will those bolts still be strong after 20 years???
The bolts on the Mantus are a non-issue IMHO.. Remember the CQR has but ONE pivot pin that rotates and wears... The Fortress is also bolted together as is the Spade...
It would cost you all of about four dollars to replace the bolts every ten years or so if you wanted to. They are simple grade five galvy bolts.
Each bolt in the Mantus Anchor, and there are four, is usually larger than the diameter of your shackle pin, larger than the wire diameter of your chain, and, for that matter, larger the bolts on the cleat for your boat that are holding the anchor...
The nice thing about the Mantus is that it can be stowed and made ready for a storm pretty quickly. Also if you were to bend any part of the anchor Greg will ship the part to you where ever you are...
