Arrowhead manufactures a wide range of custom fiberglass compartment doors tailored for the boat and marine industry. These molded fiberglass doors are commonly used as access hatches or storage covers on a variety of watercraft, offering strength, durability, and long-term performance even in harsh marine environments. Built with quality and consistency in mind, each fiberglass compartment door we produce is engineered to withstand exposure to sun, saltwater, and impact.

Typically manufactured at a thickness of 1″, our fiberglass compartment doors provide a robust, solid feel that gives boat owners and operators confidence in their long-term durability. In fact, these doors are often designed to outlast the life of the vessel itself. Marine manufacturers trust Arrowhead because our products hold their shape, resist degradation, and maintain their performance season after season.

A key advantage of choosing a fiberglass compartment door is the design flexibility it offers. Various surface textures can be incorporated directly into the mold—such as non-skid patterns or decorative finishes—to meet both safety and aesthetic requirements. This eliminates the need for secondary coatings or treatments, reducing production costs while ensuring a consistent surface finish.

Whether you need a compartment door for a small fishing boat, a high-end yacht, or a commercial marine application, Arrowhead can develop a custom fiberglass solution to match your exact specifications. We work closely with boat builders to ensure proper fit, finish, and function—delivering high-quality molded components that enhance the performance and appearance of every vessel.

The open molded fiberglass hood is a popular solution for large, contoured components in the transportation industry—especially in applications like buses, trucks, and specialty vehicles. One of the key reasons fiberglass is the preferred material is the significantly lower tooling cost compared to other molding processes. This is especially important for large parts that feature compound curves, complex surfaces, or molded-in details. Open molding allows manufacturers to produce durable, cost-effective hoods without investing in expensive, multi-cavity tooling systems.

An additional benefit of using an open molded fiberglass hood is the material flexibility it offers. The type and quality of fiberglass reinforcement—such as chopped strand mat, woven roving, or multi-axial fabrics—can be selected based on the strength, weight, and cost requirements of the project. This customization enables design engineers to fine-tune performance characteristics, ensuring long-term durability with minimal added weight. This is particularly advantageous in industries where reducing vehicle weight can lead to increased fuel efficiency and improved overall performance.

The open molding process also provides flexibility in integrating functional features into the hood. Structural brackets, reinforcing ribs, hinge mounts, and other hardware can be mechanically fastened, laminated in place, or bonded to the backside of the part during or after the molding process. These additions enhance both the strength and usability of the hood, allowing for seamless assembly with surrounding vehicle components.

Arrowhead specializes in producing high-quality open molded fiberglass hoods and similar components, offering engineering support, in-house tooling, and precision manufacturing to meet your unique project requirements. Whether you need a single custom prototype or a low-to-medium production run, open molded fiberglass offers the versatility, cost savings, and performance you’re looking for.
