The hull should be constructed from FRP (Fiber Reinforced Plastic) or GRP (Glass Reinforced Plastic) for superior corrosion resistance and high strength-to-weight ratios. Key components to inspect include the release mechanism (on-load/off-load), which must be fail-safe, and the buoyancy material, typically high-density polyurethane foam, which must ensure the boat remains afloat even when flooded. Additionally, check for UV-resistant gel coats to prevent material degradation under prolonged sun exposure.
