The bow wing tubes were built in-house using a foam core construction, allowing seamless integration of the bow net lashing tubes and full control over geometry and laminate quality.
The plans call for a 75 to 80 mm fiberglass or carbon tube. Instead of buying such a tube, I decided to make the bow wing tubes myself using a simple and lightweight foam core construction. The core consists of five laminated layers of 15 mm Corecell, shaped to the required diameter.
This construction method also allows the bow net lashing tubes to be integrated seamlessly into the bow wing structure, without secondary bonding or complex joints.
This photo gallery (24 images) documents the complete construction of the bow wing tubes, from foam core lamination and shaping to installation, vacuum bagging, and the integration of the bow net lashing tubes.
