Description

Dinghies usually range in length from about 6 to 20 feet (2 to 6 m). Larger auxiliary vessels are generally called tenders, pinnaces or lifeboats. Folding and take-down multi-piece (nesting) dinghies are used where space is limited. Some newer dinghies have much greater buoyancy, giving them more carrying capacity than older boats of the same size.
Many modern dinghies are made of synthetic materials. These require minimal care and do not rot but can suffer from fibre glass pox which is caused by the ingress of saltwater through the gel coat. Inflatable dinghies can be made of fabrics coated with Hypalon, neoprene or PVC.[1] Rigid dinghies can be made of glass-fibre reinforced plastic (GRP) but injection-moulded one-piece hulls are also available. Other materials for modern rigid dinghies include aluminium, marine plywood which tends to be much lighter than most types and, with the advent of sturdy, UV resistant polyurethane varnishes, wood. Some wooden dinghies (especially of classic or historical form) are built using the carvel or clinker methods. Favoured woods, in order of rot-resistance, are White oak, Black locust, species of cedar and pine, true as well as African and Asian mahoganies, fir and spruce. Rot resistance depends on paint as well as protection from rainwater . Plastic hardware is sometimes used, but bronze and stainless steel are good corrosion-resistant materials for hardware, although stainless steel can be subject to crevice corrosion after many years especially in a boat using an outboard or other motor and must be inspected. Stainless steel should never be used for fittings permanently in the water. Owners should check that the correct grade of stainless steel is used in a fitting .Working boats may use lower-cost galvanized steel, but the hardware may need to be re-galvanized or replaced eventually.
