The "Small Split Boat" is a boat designed to be disassembled and assembled by dividing the hull into two or three parts, either front and back. By splitting the hull, it allows for easy transportation and storage, while still providing a substantial size and a fully functional shape during operation, ensuring convenience in terms of navigability and interior space. Additionally, our FRP split boat employs a unique "full circumferential interlocking method" that has a long track record in connecting the hull. It not only flexibly withstands complex forces such as wind and waves but also allows for assembly and disassembly in just 10 to 20 seconds once accustomed, making it easy for even first-time users to handle alone. [Features] - Easy transportation and storage by splitting the hull - Becomes a substantial and fully functional boat during operation - Ensures convenience in navigability and interior space - Adopts a unique "full circumferential interlocking method" - Easy for even first-time users to handle alone *For more details, please refer to the PDF document or feel free to contact us.

The "OPA Light 3 Origin" is a compact split boat that has been lightened by 6 kg from the split boat "OPA S3," designed specifically for a 2-horsepower outboard motor. It meets the standards for mini boats, so no boat inspection or license is required. It can be easily used by many as an introduction to boating life, or as a transition from canoes, kayaks, or inflatable boats. It is recommended for those who find rowing unsatisfactory but do not want to incur too many fixed costs. Additionally, we offer many optional items for those who want to further enhance safety and convenience. 【Features】 ■ 6 kg lighter than the split boat "OPA S3" ■ Designed specifically for a 2-horsepower outboard motor ■ No license or boat inspection required ■ Fully complies with the technical guidelines that define the safety of mini boats ■ Hull features a full surround interlocking design *For more details, please refer to the PDF materials or feel free to contact us.

The "OPA S3 II" is a small boat that excels in balancing price and performance, not only loved by many fishermen but also used by professionals for tasks such as environmental surveys. It pairs exceptionally well with the "Miracle Float," a flip-up float that can be installed in 10 seconds and flipped up in 1 second. When using a 6-horsepower outboard motor for fast travel, the float in the flipped-up position does not hinder movement at all, allowing for smooth sailing. With a total length of less than 3.3 meters, when used with an outboard motor of less than 2 horsepower, it is classified as a mini-boat (2-horsepower vessel), which does not require a small vessel operator's license or vessel inspection. [Options (excerpt)] ■ Flip-up float ■ Original dolly ■ Wave blocker ■ Original float & hull modifications ■ Wooden outboard motor stand *For more details, please refer to the PDF materials or feel free to contact us.

The "Opa Light 3 Advance" is a small split boat that has reduced the weight of the split boat "Opa S3" by 3 kg while accommodating outboard motors up to 5 horsepower. While inheriting the main specifications and features of the Opa Light, it is compatible with higher horsepower outboard motors. Additionally, we offer a variety of optional items for those who want to further enhance safety and convenience. It complies with vessel inspection standards, making it suitable for those who find mini boats insufficient and eventually want to obtain a boating license for longer trips. 【Features】 ■ 3 kg weight reduction of the split boat "Opa S3" ■ Compatible with outboard motors up to 5 horsepower ■ Sturdy and convenient split design ■ Complies with vessel inspection standards ■ Well-suited for the "Miracle Float" (flip-up side float) *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce the philosophy and theory behind the design of the "float" for our boats. The float body features the excellent durability of the "Big Fender" manufactured by the American company Polyform, which protects large cruisers worth hundreds of millions of yen. Our FRP boats can typically be used for over 20 years. Additionally, the support brackets can be auto-locked with just the insert, and they feature a new mechanism that allows for unlocking in two stages. 【Features】 ■ Durable and long-lasting ■ Easy to maintain ■ "Flip-up float" that does not obstruct during operation ■ The ability to flip up the float significantly enhances comfort during operation ■ A unique structural design that skillfully blends areas focused on strength with areas focused on flexibility *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce the philosophy and theory behind the design of the "hull" of our company's boats. Through various tests, including those conducted at industrial testing facilities, we have demonstrated that our hulls possess the strength to withstand pulling tests exceeding 3 tons. By using the same FRP material as the hull throughout the entire joint cross-section and significantly reinforcing the joint areas compared to the average strength of the hull itself, we achieve overwhelming strength and durability. The hull section that supports the floats incorporates structures and theories that were being researched and developed at the time for aircraft and racing cars, which are applied to the hull reinforcement areas. 【Features】 ■ The boat body is produced in-house with a consistent process. ■ A thorough commitment to using world-class materials. ■ A special reinforcement structure theory for the hull area where the floats are attached. ■ Designed to ensure the entire bottom of the boat is flat. ■ The bow section is rounded, adopting a wide-bottomed hull structure. *For more details, please refer to the PDF materials or feel free to contact us.
