China is the emerging market of yacht industry, and our current registratied records of the yacht have more than 1000 ships. The import value of the yacht reached $110 million in 2008, and the rate of increase was more than 40% in 2009. In the yacht industry, China has become a second only to Japan and Hong Kong, then in five years we will be expected to rank first in Asia. In the next 10 years, China's yacht industry will have an annual average rate of more than 30% to embrace a new boom in this industry. Various kinds of activities of those professional BBS, such as Haikou Yacht Economic BBS, World EXPO Yacht BBS, Across-strait Yacht Cooperation BBS, Jalor Industry BBS and so on, not only attracted wide attention from all fields but also enhanced the public comprehension of yacht and promoted the industry and policy-making department's communication.

Our company steps into the new yacht industry based on crosslinking PVC construction foam core material. In order to reduce the weight of high-speed hull, we adopt FRP sandwich structure on side plating, deck, hull bottom, bulkhead, and wall board of the superstructure deck room. These boards are mainly affected by some different load-carrying forms like lateral bend, compressing and shearing, therefore they needs a higher requisition of the core materials. At present, Cinch Sun corporation has made great achievements in the applications of yacht FRP sandwich materials.

l Cellular material: This kind of material can be metal, aramid/ phenolic aldehyde composite material, plastic and paper. Features: High compressive strength, and low density; but it is not suitable for liquid resin molding process and also not for manufacturing some products which contacts with water.

l Balsa Wood：Natural products, grow in Ecuador and many other countries of South America. Features:The vertical fiber structure, high compressive strength and shearing strength; but uneven performance, easy to mildew, and restricted output.

l Structural foam material: Synthetic materials products. Features: Uniform and stable performance, favorable fatigue resistance, waterproof and mildew proofing.
