With the good fortune of having built the Godzilla 22 tug and seeing how she moved through the water and experiencing just how damn much fun a small cruiser/workboat like her can be, I was inspired one afternoon to start working on drawings for a small workboat/launch that could be serviceable for our boatshop.
What was needed was a boat small enough to not be a hassle to maintain and keep up properly and yet be stable enough to do all the myriad of jobs such a vessel is required to do with stability and style. We needed a launch to do jobs that could be as simple as ferrying us out to the moorings in deep water of our bigger boats, setting crab pots, or when needed, to tug larger vessels into the Marine Railway for bottom painting or servicing. That is a lot to expect of a small boat and a couple of extra requirements were necessary that really could put a crimp into the design of a boat. Our shop inlet is very tidal with a daily average of a 12 - 14 foot range from high to low water. At low tide, there virtually isn't any water in the immediate small cove that the shop sits beside and the docks sit on soft deep mud with clams and barnacle covered oysters strewn about on its surface. Thus any small workboat that is going to be really serviceable should have the capability of sitting out the tide on its mud berth day after day without damage or excess wear.
An inboard diesel engine would be nice for the "tug" purpose of this small design but I discarded the option of the inboard due to the deeper keel necessary to protect the propeller and rudder.
