The MacGregor 26 is built to outlast all of us. Each boat is built of individual layers of fiberglass fabrics, laid in place by hand, in a carefully controlled process. Hulls and decks are light, but strong, with extra reinforcement at all high stress points.
Most of our competitors use "chopper guns" to build their boats. These are devices for spraying a mixture of resin and very short strands of fiberglass. We don't use them, even though they reduce cost. They result in heavy laminates with low fiberglass to resin ratios, accounting for much of the excess weight found in many competitor's boats. Light weight is the key to easy trailering and to high performance.
We have stayed away from sandwich construction. Most of the failures of fiberglass hulls involve the rot or delamination of balsa or foam core materials. We use only solid fiberglass laminates in the 26's hull. If exposed to water for long periods, balsa coring material can rot and literally turn to soup, causing major structural problems. Balsa is fine, in our opinion, for decks and structures that are not constantly immersed in water, as long as there is no balsa near holes for hardware. Foam cores are also widely used for stiffening hulls, however, they offer less than 200 lbs of adhesion per square inch. That is not much better than rubber cement. It takes over 2500 lbs per square inch to delaminate the resin bond that holds our hull laminates together.
Our bolted hull to deck joining system is strong, but compact, and adds little to the width of the boat. Many of our competitors use wide joining flanges, which contribute a lot to their beam, but add very little to strength or usable inside space.

Production begins with the spraying of the exterior color (polyester gel coat) on a highly polished and waxed 3 ton hull mold. The waterline and accent stripes are also sprayed on at this point.

Alternating layers of fiberglass fabrics are then applied. Each layer is saturated with resin and all air and excess resin is removed. The resulting laminates are of the highest quality.

Here the cured hull is being removed from the mold. Notice the high gloss and molded in stripes. All the fiberglass parts are built in precision molds in the same manner as the hull.

This is the deck being removed from its mold. The window accent color and the non-skid surfaces are molded in. The deck liners have already been bonded in place.

Hardware is then attached to the deck and hull. The fiberglass thickness is greatly increased where each load carrying item is located, and all items are thru bolted, with large backup washers.

The hull and dick are joined with 3/16" bolts on 4" centers. Top grade adhesive is used to insure a watertight seal. Many builders use screws or pop rivets for this joint. Bolts are better.

These are the parts that make up the boat. At the left is the hull, still in its mold. Notice that the water tank and centerboard trunk are molded in as part of the hull. Next is the hull liner, then the deck, and then the deck liner. Rudders, bullkheads and other smaller parts are around the perimeter.
