Introduction
This document discusses the innovative design and construction of the SeaRock XR7, a high-performance exploration boat made from high-density polyethylene (HDPE). The document highlights the unique properties and advantages of using HDPE in boat construction.

Specifications
The SeaRock XR7 is a 7.20-meter-long exploration boat with a beam of 2.40 meters and a draft of 0.47 meters. It has a displacement of 1,350 kg when empty and 2,700 kg when fully loaded. The boat is powered by an outboard motor ranging from 200 to 300 HP.

Construction Method
The construction of the SeaRock XR7 is similar to that of aluminum boats, using HDPE panels of varying thicknesses. These panels are cut using CNC technology and then interlocked and welded together. The welding process uses extruders at low temperatures, minimizing energy consumption and avoiding toxic fumes.

Material Advantages
HDPE offers several benefits, including being indestructible, unsinkable, flame-resistant, and maintenance-free. It is also recyclable and does not require antifouling treatment. The material's robustness and elasticity make it highly resistant to collisions and grounding.

Limitations
The boat's weight is over 1,300 kg when empty, and its aesthetic is limited by the availability of UV-filtered HDPE sheets, which are currently only available in black. This results in a minimalist, "post-apocalyptic" look. Additionally, the use of HDPE panels restricts the hull's design to simpler shapes without double curvatures.

Conclusion
The SeaRock XR7 represents a novel approach to boat construction, utilizing a new material and method designed for maximum safety and durability in extreme conditions. SeaRock is awaiting a patent for this construction method, which promises to revolutionize the nautical industry.
