Cutting into a fiberglass boat can be a tricky and unpleasant task, but it is often necessary for installing new equipment, such as a radio or a plug receptacle. Before cutting, it is important to plan ahead, use the right tools, and take the necessary safety precautions. Safety goggles, gloves, a dust mask or respirator, and long sleeves are recommended to avoid contact with dust and debris. Drilling holes into fiberglass requires careful measurement and placement to avoid costly repairs in case of mistakes. When cutting, it is crucial to use a sharp, fine-tooth blade designed for metal cutting to prevent chipping and cracking of the fiberglass.

What You'll Learn
Wear gloves, a dust mask, goggles, and long sleeves to avoid contact with dust
When sawing a fiberglass boat, it is important to wear gloves, a dust mask, goggles, and long sleeves to avoid contact with dust. This is because working with fiberglass is, at best, an unpleasant experience.
Goggles will protect your eyes from any flying debris, and a dust mask will prevent you from inhaling the fiberglass dust, which is an irritant and can be harmful to your lungs and respiratory system. It is also a good idea to wear long sleeves to protect your arms from the dust and any other debris. Gloves will protect your hands and wrists from irritation and any cuts or splinters.
It is also important to vacuum up any dust immediately to avoid tracking it all over the boat. This will help to ensure that you do not accidentally come into contact with it later or breathe it in.
Before you begin sawing, it is also a good idea to prepare the fiberglass in advance with appropriate boat cleaners. You should also ensure you are working on a relatively clean, smooth surface.

Use a jigsaw with a fine metal-cutting blade
When sawing a fiberglass boat, it is important to take the necessary safety precautions. Wear gloves, a dust mask, goggles, and a long-sleeved shirt to avoid contact with the dust. Vacuum the dust immediately to avoid spreading it all over the boat.
When using a jigsaw with a fine metal-cutting blade to cut a fiberglass boat, there are several steps to follow. First, choose a jigsaw blade with a fine pitch, ensuring that at least two teeth are in contact with the fiberglass at all times. This will help prevent the blade from burning out due to excessive heat.
Next, mark the cut-out area with a template or pencil, ensuring that the corners are rounded to prevent spider cracks. Drill holes at each corner, being careful not to drift outside the marked line. Then, insert the fine metal-cutting blade into the hole, making sure the base plate is clean, smooth, and firmly in contact with the gel-coated surface.
Cut slowly and steadily just inside the line, repeating the process between each hole. To prevent chipping, you can apply painter's tape to the boat and the bottom of the jigsaw. After cutting, clean up any mess and fit the equipment into the new hole. If necessary, use a suitable file to ease the opening.

Avoid coarse blades intended for wood
When cutting fibreglass, it is important to avoid using a coarse blade designed for wood. Coarse blades can cause the fibreglass to vibrate, which may lead to chipping and cracking of the surface and laminate. The thinner the fibreglass, the more susceptible it is to vibration and potential damage.
Fine-tooth blades are more suitable for cutting fibreglass. A jigsaw fitted with a fine metal-cutting blade can be used to cut between holes in the fibreglass. Alternatively, a hand-held hacksaw with a fine-tooth blade, a portable bandsaw, a chop saw with a diamond-cutting blade, or an abrasive blade cutter can be used.
When cutting fibreglass, it is important to take safety precautions to prevent injury and damage to the material. In addition to using the correct blade, it is recommended to use a guide to ensure accuracy and prevent mistakes. It is also important to wear protective clothing, such as gloves, a dust mask, goggles, and a long-sleeved shirt, to avoid contact with dust and debris.
Some people have reported success using a carbide grit or carbide-tipped blade with a sawzall when cutting fibreglass. These blades are durable and able to handle the abrasive qualities of the material. However, it is important to consider the thickness and length of the blade, as well as the specific project requirements, when selecting the appropriate blade.
It is worth noting that cutting fibreglass can be challenging and unpleasant due to the dust and vibrations. Taking the time to choose the right tools and following safety precautions can help ensure a successful and safe outcome.

Seal out moisture if cutting through cored fibreglass
When cutting through cored fibreglass, it is important to seal out moisture to prevent water intrusion. Water intrusion can cause core degradation, weakening the structure of the boat.
To seal out moisture, you can follow these steps:
- Drill a hole through the outer fibreglass skin and the coring, but not through the inner fibreglass skin. Use a drill bit that is the appropriate size for your screw.
- Ream out the core around the hole and vacuum away any debris.
- Backfill the hole with thickened epoxy resin. Allow the resin to soak into the coring for a few minutes without curing, then push out any excess.
- Drill a pilot hole in the epoxy plug using the appropriate size drill bit for your screw.
- Apply a heavy coat of epoxy resin to the inside of the hole before applying thickened epoxy to create a plug. This will help to create a stronger seal.
- After installing any hardware or accessories, bed them in marine sealant to prevent water intrusion.
It is important to note that different types of sealants have their own strengths and weaknesses. Common sealants include silicone, polyurethane, polysulfide, elastomeric, and butyl tape products.
Additionally, it is recommended to remove deck fittings and accessories every three to five years to scrape away old sealant and re-bed them with new sealant.
By following these steps, you can help to seal out moisture when cutting through cored fibreglass, maintaining the structural integrity and performance of your boat.

It's safe to leave a fibreglass boat in saltwater for up to two weeks
It is safe to leave a fibreglass boat in saltwater for up to two weeks. However, constant exposure to saltwater and the sun's UV rays may cause minor cracks and give your boat a faded look. Therefore, it is recommended to use a growth repellent and wax the boat regularly.
When cutting fibreglass, it is essential to take the necessary precautions as the process can be unpleasant and hazardous. Wear gloves, a dust mask, goggles, and a long-sleeved shirt to avoid contact with the dust and fibres. It is also important to use the correct tools, such as a drill with a sharp twist bit or a hole saw for larger radiuses. A jigsaw with a fine metal-cutting blade can be used to cut between holes, but a coarse blade intended for wood should be avoided as it can crack the fibreglass.
When cutting, it is crucial to work slowly and steadily, and a vacuum can be used to immediately remove any dust and debris. Additionally, the cutout for any equipment will typically have rounded corners, which can be achieved using a drill.
While fibreglass is durable and water-repellent, leaving it in saltwater for extended periods may corrode metal parts and cause algae, barnacles, and other organisms to grow and damage the hull. Therefore, regular maintenance, such as washing the boat and applying gel coat and wax, is essential to prolong its life.

Yes, it is safe to saw a fiberglass boat. However, it is important to take the necessary precautions and use the correct tools and safety gear.
When sawing fiberglass, it is important to wear gloves, a dust mask or respirator, goggles, and a long-sleeved shirt to avoid contact with the dust and debris.
A jigsaw fitted with a fine metal-cutting blade is recommended for cutting between holes in fiberglass. A drill is also necessary for creating the holes.
It is important to work on a clean, smooth surface and use masking tape to protect the boat's surface. Thin fiberglass may flex, so extra caution is needed to avoid cracking the surface.
A fiberglass boat can be cut into smaller pieces for disposal. A reciprocating saw with a metal-cutting blade can be used for this purpose, but it is important to take your time and wear a mask to avoid inhaling dust. Additionally, leaving a fiberglass boat in saltwater for an extended period may result in marine growth and corrosion.
