Building a Fibreglass Catamaran – Engines & Sanding Details
In the latest episode of Life On The Hulls, Sam, Zach, and Janet delve into the intricacies of building a fibreglass catamaran. With meticulous attention to detail, they explain how to prep Yanmar engines and ensure every part of the boat is perfectly sanded for the final spray.
Fitting Yanmar Engines
The team first discusses their approach to preparing the Yanmar engines. They share tips on checking impeller integrity and explain how to inspect, remove, and replace impellers. This is crucial for ensuring the engines operate efficiently without any risk of damage from broken fins.
Sanding The Deck
Next, Sam, Zach, and Janet take viewers through their sanding process on the boat’s deck. After six hours of sanding with orbital sanders, they discuss how this extensive work pays off in achieving a smooth finish. The episode reveals that each person dedicatedly spent 6 hours to this task, making it clear just how significant this step is for preparing the deck before the final spray.
Plumbing Fuel and Cooling Lines
In addition to engine prep and sanding, the crew focuses on plumbing fuel and cooling lines. They detail how to prime the fuel system correctly and set up a secondary filter before testing. Furthermore, they discuss strategies for protecting their work from dust and possible damage.
Final Thoughts
The episode wraps up with an appreciation of the progress made thus far in building this fibreglass catamaran. It showcases the dedication required to maintain high standards of workmanship and preparation. This insightful video offers valuable lessons on engine fitting, sanding techniques, and important safety measures that can benefit both amateur and professional boat builders alike.
There seems to be no end to the sanding required to finish a Fibreglass Catamaran. Building it right the first time is our mandate, no leaky seams, no failing deck join, it is obvious that some Cat owners are doing it tough out there fixing known and unknown quality issues, I won't have any of that, do it once and do it right.
Our YouTube build series is all about what it takes to build a Catamaran from Scratch. There is so much detail in a build of this size and so many different techniques involved in bringing her to fruition. I trust you will find something that may help with your current or future project, repair or dream boat build.
