Definitions

  • the invention relates to water boards, and particularly, but not exclusively, to surfboards, paddleboards, crossover surf/paddle boards, bodyboards, skimboards and wakeboards.
  • surfboards many types of board for use on water, such as surfboards, paddleboards and crossover surf/paddle boards, exist. These comprise a basic elongate shape, providing a flat deck or platform for a user to stand on and a generally curved base which contacts the water.
  • Surfboards are made in various lengths, from 'longboards' of lengths between 2.4m and 3.7m to 'shortboards' of lengths between 1.8m and 2.1m and several varieties inbetween.
  • Paddleboards where the user lies, kneels or stands on the board) are also made in different lengths, from 2.7m to 5.5m or more.
  • the curve of the base of these water boards can be concave and/or convex, continuous or staged, steep or shallow. Details of the outline shape of these boards, particularly at the front end, the nose, and at the rear end, the tail, varies, for example the tail shape can be square, rounded, pin (pointed), swallow, etc.
  • Water boards are normally provided with one or more fins, usually attached to the tail of the board. One, two, three or more fins can be used, providing various degrees of stability and manoeuvrability. The variation of the characteristics of water boards which is available allows boards to be created which can be used for different functions, e.g. surfing or paddling, and which can be customised to suit the user's skill and experience.
  • Water boards as described above can be 'hard' boards, usually made from plastic or fiberglass, or 'soft' boards usually made from a foam material.
  • Soft boards in particular, generally comprise a number of components, such as a core of foam material, surrounded by a deck, a base and a rail, which are attached together using a variety of methods.
  • Such soft water boards are light and buoyant and sufficiently strong to support the user, and are designed and manufactured to different levels of robustness and durability.
  • Soft water boards are often used by beginners and less experienced users, such users can subject the boards to a high level of abuse.
  • Soft water boards are also often used in schools for teaching surfing and paddleboarding, etc. and are used a large number of times per day. The boards are also subject to varying temperatures, from cold seas to summer sun.
  • AN of these ca n result in problems with the robustness of the boards. For example, delamination may occur, where the base or deck separates from the rest of the board. When the base of the board is made from plastic, sharp edges can be created on the base through damage. These problems cannot usually be repaired and renders the board useless. It is an objection of the invention to provide enhancement of robustness in water boards.
