Working within the Windsurfing Industry has taught me many things, one being that people LOVE their Fiberspar Carbon Booms. These booms were, and still are, top of the line carbon booms that perform to the highest standards. With features such as durability, weight reduction, and many other performance driven aspects. Keeping your Fiberspar Booms up to par and functional is one of Wind Power’s top priorities, we offer many different Fiberspar parts to keep them on the water. Link to Fiberspar products.
Today we want to discuss a common issue with the Fiberspar Carbon booms, the issue regarding why some windsurfers need to replace their Fiberspar Carbon boom Twist Locks when the tabs on the inside fingers of the Twist Locks start to wear down. Located below in Image 1 is a close up of how the locks are positioned on the boom end and in Image 2 the tabs on the fingers.

When this happens, the boom end is able to slide freely, not allowing the tabs to properly lock onto the certain notch. This is an obvious issue when wanting to rig different sized sails. Luckily Wind Power has a large quantity of OEM replacement Fiberspar Twists Locks and the “know how” to help you replace them yourself. With the help from this short blog, you will be able to fix any Fiberspar Boom whose twist locks have failed!
Wind Power has created a great video starring Wind Power’s very own Kevin Gratton. It is a fantastic video that goes into great detail on how to replace the Fiberspar Twist Locks and little hints to make sure everything goes smoothly through the process. This video is a great guide and the visuals will help you to understand the process. The link to Wind Power’s Fiberspar Repair Video can be found here.
Alright, let’s get into the first steps in replacing your Fiberspar Twist Locks! The first step in the process is to gather your Fiberspar Carbon Boom and all your equipment/tools needed for the repair. The tools needed for this install can be found on the instructions sheet which is located here. Next we will remove the boom end to easily work on the boom and to avoid any damage to the boom end. We need to remove the old twist locks, the best method we found is using a hacksaw and cutting at an angle lengthwise. Make sure to only cut into the plastic and to not cut too deep that you cut the carbon arm, just go slow and you will be fine. After it looks like you have cut all the way through the plastic, take a Flathead screwdriver and twist your wrist to pry open the cut you just made. This will force the twist lock off of the carbon arm and remove the twist lock. After you have removed the plastic lock, you will need to sand the excess epoxy that is on the arm.
When you begin to sand the arm to remove the epoxy, the best method is to rip a large piece of emery cloth and sand it similar to how you would polish a shoe. This is shown in the video, this will give you the most even sand on the arm and ensure you get each side evenly. Start on the bottom of the arm, then flip the emery cloth over and continue on the top. Continue to check to see how the new lock slides onto the boom arm, it should slide on and off very easily, if not continue sanding. After your twist locks fit onto the boom extremely well, sand the inside of the locks themselves. This helps for the adhesive to stick to the plastic and helps ensure that it adheres properly. After sanding everything it is suggested you wipe down the surfaces that were sanded. This is a precautionary measure to make sure everything is clean and there’s no debris.
Now that your locks fit properly and you have everything sanded and prepped you are now ready to begin mixing your adhesive! Kevin has a great little trick to remove the adhesive from the package quickly and mess free, just simply take the stir stick and use it to push the adhesive out. Stir the two parts together and begin applying the mixture generously to the boom arm and inside the lock itself, any surface that is being glued is suggested to receive a little adhesive. Now that your adhesive is applied to your boom arms you can begin putting the locks on, while pushing the locks onto the arms, slowly turn the lock in a clockwise motion to evenly distribute all of the adhesive. Position the lock tabs where you believe is the best location.
After your locks are firmly pressed onto the boom arms it is essential that you look into the tubes where the boom end slides into. Take a rag or paper towel and wipe any excess adhesive out of the tube, if there is any adhesives in the tube and it drys like that you won’t be able to install the boom end and you will need to use a Dremel tool or sandpaper to remove the excess adhesive. It is also recommended to remove any excess adhesive from the outside of the locks, removing this adhesive give the locks a more professional appearance after the adhesive dries. After everything is cleaned and positioned correctly we recommend taking packaging tape and tape the locks into place. Use a decent amount of pressure to ensure a solid connection, sometimes when the adhesive dries it pushes the locks forward and out of position so it is better to just tape them into position ensuring they will not move. Let you boom sit for approximately 2 hours and you will be able to remove the tape.
Once you remove the tape exposing your brand NEW Fiberspar locks, it is EXTREMELY important to put the twist lock caps ONTO the locks. This is displayed in Image 4 located below. If the caps are not put onto the locks then you risk the chance of breaking the fingers off of the locks when trying to install the boom end. This is a simple step but can be overlooked at times… speaking from experience. Once the caps are placed onto the locks you are ready to install your boom end! It is recommended you find a partner when installing the boom end, it makes it much easier, but it can be done solo. If you are attempting to install the boom end solo, apply pressure to the boom end pushing the ends towards each other and taping the boom end. For a reference to this, you can find it in our video when Kevin installs the boom end himself.
