Large - Offshore/Sport to 40', Cabin Cruiser to 32' With no chain and a 2 to 1 scope, it's the best and easiest anchor you'll ever buy! The state-of-the-art anchoring system for boats of all sizes and types, in any water. Developed for the most severe water conditions - it requires NO lead chain* ... Half the anchor line of conventional anchors... SETS quickly in almost any bottom condition... retrieves easily... and folds flat for storage! Just toss it and GO... no chains required*, and no powering down! The BOX ANCHOR sets on either side it falls. In deep or shallow water, it's fixed scoop design and narrow side panels set like a "cookie cutter" into sand, mud, grass or rock. Narrow side panels elminate resistance upward for easy retrieval. Wind or current changes are no problem - resets in seconds. The stainless stell stabilizing bar and return spring make quick work of locking the anchor open for use - or collapsing the anchor for compact storage. Hot-dip galvanized with stainless stell hinge pins, stabilizing bar, return spring, and nut for years of corrosion-resistant performance, including in salt water. (*) while the Box Anchor works great offshore, it is advised that when using the Box Anchor offshore to use a length of chain on the anchor in the unprotected waters to compensate for the swell and to further reduce line chaffing.
