Anchor and chain is so afecting performance that I remove everything (anchor, cahin, rope, roller battery and
windlass) off the boat for racing season. And I only have 15 meters (50 feet) of chain, the rest is rope.
My
anchor weighs 24Kg (50 lbs). And its enough for my crusing needs. I have a secondary 14Kg one in case I need a tendem set up.
If you think in terms of momentum...you will have 6 or 7 tons load there.
