What this video covers
Sven Yrvind modifies the bow mast holder on his boat to function as a reinforced bollard. The construction utilizes a D11 epoxy laminate pipe that extends down to the waterline, providing structural integrity for towing or hauling the vessel.▶ 0:57 The assembly features a roof-like cap to prevent lines from slipping off the top.▶ 1:44 Yrvind reinforces the structure by applying two layers of 450-gram glass fiber oriented at 45-degree angles.▶ 1:56 This bollard design allows the boat to be pulled by a tractor while on land or towed by a fishing boat when grounded on a beach.▶ 2:35 The completed installation provides a high-strength attachment point capable of supporting the weight of the small vessel.
