Building a Root Cellar Using a Burying a Sailboat

Introduction

This guide details the process of constructing a root cellar using a fiberglass sailboat buried in a hillside. This innovative approach repurposes an abandoned boat into a functional and durable food storage solution. By following these steps, you can create a unique shelter that not only preserves food but also serves as a potential emergency shelter.

Selecting the Right Boat

Choose a fiberglass sailboat with a durable hull and no metal parts. A 29-foot sailboat with intact decks and no hardware is ideal. Ensure the boat is free of rust or metal parts that could degrade over time. Fiberglass is preferred for its water resistance and durability. Inspect the boat thoroughly for any cracks or damage that could compromise its integrity.

Digging the Hole

Use a backhoe to excavate a 12-foot-deep hole into a hillside. The hole should be slightly larger than the boat’s dimensions to allow for maneuvering. Create a ramp of sturdy logs to roll the boat into the hole. The ramp must be strong enough to support the weight of the boat and any workers. Ensure the hillside is stable and free of loose soil or rocks that could collapse during the excavation process.

Sealing the Boat

Apply a thick layer of black foundation sealer to the entire exterior of the boat. This step is crucial to prevent water seepage. Install PVC pipes for ventilation, lighting, and solar panel conduit. Ensure all pipes are securely fastened and sealed to prevent leaks. The pipes should be positioned strategically to allow for proper air circulation and easy access to the root cellar.

Insulation and Structural Modifications

Add 2-inch foundation foam insulation between the cockpit and cabin for thermal control. This step is essential for maintaining a consistent temperature inside the root cellar. Cut the transom for easy entry. Reinforce the transom with additional framing to ensure structural integrity. Add side walls and a peaked roof to accommodate the boat’s curved shape. Ensure all modifications are structurally sound to prevent collapse. Custom-built furniture should be made from weather-resistant materials to withstand the damp environment inside the root cellar.

Testing and Outfitting

Store a 50-pound sack of potatoes in the bow to test the root cellar’s effectiveness. Temperatures should remain above 35°F even in winter. Regularly check the temperature inside the root cellar to ensure it remains within the optimal range for food storage. Outfit the root cellar with shelves, a bed frame, and storage compartments. Future plans may include converting the cockpit into a heat source for a bunkhouse and adding a false floor in the keel for expanded storage. Custom-built furniture should be made from weather-resistant materials to withstand the damp environment inside the root cellar.

Summary

Building a root cellar using a fiberglass sailboat buried in a hillside is an innovative and practical solution for food storage and emergency shelter. By following the steps outlined in this guide, you can create a unique and functional space that repurposes an abandoned boat into a valuable asset. This project demonstrates the potential of repurposing old materials into functional and innovative solutions for food storage and shelter.

TLDR: Choose a fiberglass sailboat, dig a 12-foot-deep hole, seal the boat with foundation sealer, add insulation, and outfit with custom furniture. Ensure all modifications are structurally sound and regularly check the temperature inside the root cellar.
