No one mentioned Bulwagga Anchors
I attended a Docking and Anchoring seminar at the AC Boat Show this winter. The speaker had good things to say about it with the exception of storage due to its shape.
I liked it also, but I went with a Fortress FX 16 for my C&C 30 because it is LIGHT and I don''t have a bow roller. The design seems to suit the sandy/muddy bottoms here in LI/Bock Island Sound.
