Lineage:

This design kit is a modification of our similar 24 footer (#467). It has been built in both console and tiller versions for a large scale infrastructure construction & engineering firm for use on their marine projects. It's a relatively portable, support boat for marine services- essentially a rugged, self-propelled tool box, work platform and personnel shuttle. The shape, with an easily twisting bottom and little curvature elsewhere, is quite easy to build.
