Re: andiamo
There are different anchors for different fishing areas. What works in sand may not work in weeds. All of these are prone to getting stuck in reefs. Specialty anchors made from heavy pipe and re-bar work on reefs. So, figure out what kind of bottom you need to anchor in.
On the smaller boats, the Danforth anchors are popular, They lay flat when stowed away. The Delta and CQR are great anchors, but don't stow well unless mounted on an anchor pulpit.
IF you fish in shallow, weed infested areas, that have tidal movement, a heavier anchor will be needed to settle down through the weeds to the ground.
Now, if you're a bass fisherman, there are electric anchor retrieval systems. The anchor is a simple weight with flukes. The electric motor is nice for retrieval. The weight cuts through the weeds.
More important is having enough chain and anchor rode to get a 7 to 1 angle. For shallow water, I use a 100'er. For emergencies, I keep a 300'er stowed away.
