Alajuela Yachts Original Brochure
This photo is a color copy of the original factory brochure for the Alajuela 38.
Here is another page from the original factory brochure for the Alajuela 38. This page gives details about the hull construction, deck construction, molding, and hull-to-deck joint.
Pay careful attention to the section labeled “Hull to Deck Joint”. It’s rare to find boats that are constructed this carefully. Quoting from the brochure,
The joining of the hull to the deck is perhaps the most serious deficiency in most fiberglass construction. Mechanical fasteners employed by the vast majority of builders work loose as the deck and hull flex against each other. Leaks and a general weakening of the entire hull-deck combination is the result.
To overcome this deck-to-hull joining problem, the Alajuela deck and hull are designed to lock together with double bonded, absolutely watertight fiberglass seams that run the entire length of the hull. While this method is much more costly than the mechanical fastening method, it is the only type of construction that should be used for the blue water cruising boat where maximum strength and safety are a must.
