The Science

The Shorehold Booty 5000 water bladder anchor system has been tested in the real-world and is backed up by science and experience on Lake Powell's shores. 

Here you will find two  research papers investigating the physics behind the Booty 5000 water bladder deadweight anchor. One paper is written with for the engineering audience and the other is written for the average houseboat owner (see below). 

Expert Summary

Based on a detailed analysis of the underlying physics and engineering principles, the Shorehold Booty 5000 | 600-gallon water bladder anchor is a very effective solution for mooring houseboats at Lake Powell. Its success is not just about its heavy weight but is the result of a careful balance between that weight, the friction of the materials, and how it is placed. The system's effectiveness depends completely on choosing the right spot—specifically, a shoreline with a very gentle slope.

For the best performance and safety, it's recommended that houseboaters follow these simple rules:

• Look for Gentle Slopes: The anchor's holding power gets weaker as the slope gets steeper. Choosing a location with a gentle incline is the most important thing you can do to ensure stability.

• Know Your Surface: The friction is different on sand versus sandstone. Boaters should be aware that sandy beaches, while often easier to access, may provide slightly less friction than a flat, rocky surface.

• Plan for Outside Forces: The calculated holding power is the maximum the anchor can resist from sliding. You should always use multiple anchors as a safety factor to account for forces from wind, currents, and boat movement.

• Keep It Maintained: This system is not passive. You need to regularly check the tension in the lines to assure the system stays stable.

The water bladder anchor, when used correctly and with an understanding of its physical limits, is a strong and essential tool for modern houseboating that respects the needs of recreation while also protecting the environment.
