Resin Infusion
Vacuum infusion is a fabrication technique that uses vacuum pressure to drive resin into a laminate. Dry materials are laid into the mold and the vacuum pressure is applied before resin is introduced. Once a complete vacuum is achieved, resin is forced into the laminate via vacuum tubing. The vacuum infusion process offers a better fiber-to-resin ratio than hand lay-up or vacuum bagging.






Why Infuse?
Resin infused parts generally obtain higher strength-to-weight ratios than hand lay-ups or traditional vacuum bagging. Utilizing a dry lay-up with unlimited set-up time, vacuum pressure is used to drive resin into the laminate. The process is clean, efficient, and capable of producing stronger and lighter parts!





Practical Guide to Handling the Core Materials
To maintain the effectiveness of the sandwich structure three conditions must be met. First, the core must be strong enough to withstand the compressive or crushing load placed on the panel. If the core collapses, the mechanical stiffness advantage is lost. Second, the load bearing skins must form a rigid bond to the core surfaces so the skins don't creep or peel during use. This interface is called the BOND LINE. Finally the core must resist the shear forces involved. If the core shears, the skins shift and the mechanical advantage is again lost.





Rigid Pour Foam
This foam is a rigid, closed cell material with excellent thermal and floatation properties. While it is not generally suited to the classic sandwich core laminate described in this brochure, it can be poured into any closed cavity to stiffen the structure. The free rise density is 2 lbs. per cubic foot, but closed mold techniques can increase the density when required.





Tips for Using Trim Tabs
Independently controlled trim tabs compensate for differing loads and hold the boat’s attitude in crosswinds or crossing seas, easing the captain’s job of giving his crew a smoother ride. A trim tab presses down on the water coming off the transom, lifting that side of the boat — effectively changing the running surface to suit changing conditions....Read More





Buying the Right Outboard Engine:10 Tips
In the past, picking an outboard tended to be a fairly simple choice between two- and four-stroke. On the one hand you had the lightweight simplicity of two-strokes, with their excellent hole-shot and vigorous throttle response – and on the other, you had the cleaner, more refined four-stroke engines. But the need to comply with environmental standards (and the modern customer’s wish to pick the cleanest and most efficient option) has seen the choice of outboards expand enormously, with four-strokes now available from two to 350 hp, Direct Injection two-strokes across a slightly less extreme power spectrum, and an ever-expanding range of squeaky-clean electric options...Read More
