A brand of Shanghai Danfeng Yacht Sales Co., Ltd., it mainly produces rubber boats for work purposes. Colman's rubber boats are used extensively in the armed forces, border maritime and maritime security units, and are suitable for water search and rescue and border patrols. Colman's bottom is equipped with an inflatable keel and bottom wear strips for beaching, and the teardrop-shaped hull design and narrower bow allow for quick "take-off". Colman rubber boats are made of thicker materials than sport boats in their class, and the hull is heavier, allowing them to travel at high speeds even when fully loaded with people and goods, while carrying a larger motor. Due to the solid materials used, the price is also slightly expensive, which is suitable for users who have high requirements for the durability of the boat.
