Summary

This is a scale model of a Danforth type anchor, one of the most popular and useful small boat anchors, particularly excelling in sandy bottoms.  

I've owned a variety of these anchors myself over the years, and still keep one as my backup.  It stows very conveniently as far as anchors go, making it a great choice for a second anchor.  This model articulates exactly like the real thing.  I've added a picture of my smallest real danforth snug in its locker as a bonus.

This one is scaled to make with 1/16" basswood or basswood plywood, but can be scaled up or down to fit any thickness of material.  (I'm planning on making a really tiny one of out of .040 cardstock to use as a anchor for a scale model sailboat I've been building.) Check the "Tab generation" slider to keep the pieces together before assembly if you want to make it into a kit card.
