Laminate Repair: Infusion vs. Wet-Bag

By Rachael Geerts – GBI Technical Advisor

Many products, especially boats, are now being manufactured with a process called Vacuum Assisted Resin Transfer Molding (VARTM), also frequently referred to as infusion. The main topics of this article are: what infusion is, how to repair an infused part with vacuum bagging vs. infusion, and the results of our study comparing a vacuum-bagged repaired laminate and an infused repaired laminate.

THIS LITTLE PIGGY racing on Tawas Bay, Michigan

Sea Hood Repair

By Terry Monville – GBI Technical Advisor

After a few years of racing on the J22 This Little Piggy, the owner was ready to take a step back and gave me the first option to purchase it. I took advantage of the opportunity. As with many boats I’ve owned over the years, the first couple winters I plan on spending money upgrading and doing repairs. Not that a lot has to be done, but a few changes in hardware placement and re-bedding the deck hardware are at the top of my list. Continue reading

Fiberglass Repair on a Yamaha WaveRunner

By Jordan Teddleton

I wanted to purchase a personal watercraft so I’d be able to join my friends at the local lake for some fun in the sin this summer.  Like most people on a budget, I searched Craigslist for the best deal.  I needed something low maintenance, so a WaveRunner™ felt like a good fit.  After a week of looking, I found a 2004 Yamaha GP1300r that appeared to be in decent shape; however, a strangely placed sticker on the top port side turned out to be covering a painful past.

Triple Threat, 38 years old and counting

A case study in remediating gelcoat blisters

By Bruce Niederer

My father, rest his soul, and I bought Triple Threat together sometime in the mid-’80s. We raced our ’81 Pearson Flyer hard together for the next 15 or so years, including 12 Port Huron to Mac races. The purchase date is lost to history, but the details surrounding how many times the boat needed a new bottom—meaning a new epoxy barrier coat—are forever etched in my psyche. It’s all the sanding that accompanies repairing gelcoat blisters that has addled my IPA soaked cranium. One just doesn’t forget those seemingly endless hours of self-imposed torture.

Cockpit Sole Repair

by Don Gutzmer

As a technical advisor, part of my job is to guide our customers to the correct product selection and discuss proper repair procedures. Sometimes it’s a fun challenge to take on my own projects to stay busy, and it helps me learn what my customers are up against when they do similar projects. This project was repairing the cockpit sole (floor) of a 1994 Four Winns 190 Horizon. The pictures will help tell the story. Continue reading

Sea Ray 400 Seat Repairs

By Sam Magruder

I have a 1996 Sea Ray 400 Express Cruiser that I purchased in April 2014. The vinyl is in excellent condition in the cockpit. However, when someone sat in the front passenger seat (45″ wide) the back looked like it wasn’t attached. I went to the Sea Ray Owners Club website to explore the repairs and a fix for the seat. I learned that if I waited until the seat back broke, the vinyl would be damaged, and it would be costly to replace. Continue reading

Techniques for Fiberglassing Overhead

The prospect of having to fiberglass the bottom of a hull can be a bit ominous. Any type of overhead work can be frustrating, but the thought of trying to hold fiberglass in place while applying epoxy can produce nightmares for some people. This is especially true if you will be working alone. Continue reading
