That final mixture turns into a solid section of fiberglass after the liquid-string mixture exits the gun and hardens. The air-rich mixture is then rolled or squeegeed into a tight mix of fiberglass, facilitated by a catalyst. The resin and “string” mix in the air and splat against the mold for whatever size fiberglass part is needed. It’s then sliced or chopped in a specialized “chopper” handheld spray gun. Layup only required a conventional chopper gun and some hand work.Ĭhopper gun refers to the process where the resin is mixed in the air with fiberglass that is in a string form. The 26-foot length only required a single hull mold. Plank edges and all the minor details were copied and/or replicated to create the two hulls.Īll the fiberglass hulls came from the same mold at Lyman Boat Works using the equivalent wooden model. A wooden hull was always used to mold the fiberglass hulls thus the shape was the same. The fiberglass Lyman hull in this case is a clone of the wooden version. I sea-trialed both fiberglass and wooden-hulled models this past summer, and I’m now sharing my personal observations with you. The author took a ride in a 26-foot wooden Lyman at CBMM's Antique and Classic Boat Festival in St. The very slight movement of the individual planks definitely allows for a softer ride in the wooden-hulled boat than in the fiberglass model. The same hull shape done in fiberglass rides differently than the same model with a wooden hull. They feature a “clinker-built” hull planking that in a wooden boat model works with any chop in such a way that it cuts through the chop, delivering a ride that is sublimely softer than a hard-chine fiberglass boat.
