My first experience with a "new generation" anchor
was a Sarca which I bought in Western Australia
because my CQR
was just not working there. I recenly got a Mantus
which is now my favourite with the Sarca in honorable second place. If you still own any pre 1990 anchors that simply means you haven't tried a new generation anchor yet.
After you've had a new gen type you'll agree that plows, bruces and danforths etc. should all be banned. The proper way to dispose of them is to take them to the scrap metal yard, after first cutting them up into little pieces so that nobody will attempt to anchor a boat
with them again.
The only thing that keeps me awake at anchor now is that too many people are still using those old obsolete anchors, and I find it extremely aggravating to see someone anchoring
upwind of me with a plow, or any other old gen anchor. If you own any of those old things, destroy it. Please do your part to stamp out plows once and for all, so we can all sleep better in the anchorage.
