초록

플레저 선박은 주로 FRP(Fiber reinforced plastic)를 주재료로 제작되고 있으나 2000년대에 들어오면서 FRP 선체에 대한 환경오염 및 해양안전에 관한 법규 규제가 강화되고 있다. 즉, FRP는 재활용이 불가능하며 폐기시 자연에서 분해되는 데 100년이상 걸리는 매우 반환경적 특성을 가지고 있다. 일반 선체 재료로서는 강, 알루미늄, FRP를 제안하고 있으며 이에 따른 구조설계규격 및 재료설계강도를 제안하고 있다. 그러나 소형 선박에 적합한 염가 재료에 대한 연구는 전혀 진행되지 않고 있으며 단지 소형조선산 업계에서 카누나 카약 선체를 폴리에틸렌을 이용하여 제작하여 판매하고 있다. 따라서 본 연구에서는 고 밀도 폴리에틸렌을 이용하여 보트를 설계 및 제작하기 위하여 실적선을 기초로 선체의 선형을 완성한 뒤 ISO 12215-5의 소형 선체에 대한 구조설계기준을 적용하여 선체 치수를 결정하였다.

Boat or yacht hulls are mainly built using FRP composite materials. FRP boat hull manufacturing has been restricted since 2000 under international regulations on ocean environment safety. FRP composite materials cannot be recycled and require more than 100 years to biodegrade. Therefore, alternatives to FRP have been proposed by many boat builders. Steel, aluminum, and FRP are commonly used as boat hull materials. Their design specifications are proposed as Korean register of shipping. However, the design specifications for inexpensive materials for a small boat have not yet been studied. Small shipbuilders manufacture and sell HDPE canoes or HDPE kayaks. In this study, a hull form was designed based on actual boats. The thickness of an HDPE boat hull was determined based on ISO 12215-5 structural design specifications.
