Boat that pulls itself ashore

[Jon]

Hard Drive Marine Landing Craft LC7, with the patented Maxgate landing system, for, ahem, "maximizing" your landings. This is a private craft; that's "marine" as in pertaining to the sea, and not as in naval-based infantry force.

The Maxgate hydraulic spikes perform both push and pull motion. This is an unusual display that looks like this boat is wriggling up on dry land in a critical moment of evolution, or a famous scene in a B-movie where boats develop consciousness and break free of their restrictive watery prison, with the help of sympathetic humans, driving ATVs of course.

Judging from the video, this beauty is targeted to the driving-an-ATV-off-of-boat crowd, which to be perfectly honest, looks like a lot of fun.

Naval 'Landing Craft' are a little simpler. Being nearly flat bottomed and shallow draft, they run up under power to beach themselves. Normally this synchronized with rising or high tide. Their length is sufficient to allow the propellers to remain submerged. Diameters are small in proportion to pitch of common non-planing hulls, and designed for good efficiency run in reverse, allowing the boat to retract unassisted. The draft of course is reduced when troops/ equipment are offloaded. Larger [LCU] craft are equipped with a rear anchor and dedicated winch diesel for longer unloading periods, or when loads are taken on that increase the draft. That anchor, invented for landing craft in WWII, by the way is the 'Danforth', became a fixture in private boats and yachts. It is lightweight, holds securely in a variety of seabeds, and easily is disengaged by backing down on the rode. Fishing Huntington Beach and other areas off CA, with chain heading that rode of approximate boat length, I've anchored securely in rolling swells with scope of near vertical ground tackle; 100' of 1/2'' dacron + 30' feet 1/4'' chain in water at depths of 100-115'.
Anchors have been created in many designs over the centuries, search for perfect tackle continues. That isn't likely, with variations in conditions too many to compensate for. https://en.wikipedia.org/wiki/Anchor#Overview

Needs a dozer blade on the bow and a backhoe on the stern then you would have the perfect sand castle building machine
