Sell or donate boats that are still seaworthy

If your fiberglass boat is still seaworthy, you have the option to sell or donate it.

Selling your boat

Selling a used boat is similar to staging a home for sale. You want to showcase the boat in its best light, so ensure it is clean and well-maintained. Small fixes can make a big difference, such as tackling loose fixtures, peeling paint, or any worn-out upholstery. Presenting a thorough maintenance log can also reassure buyers and portray diligence in your boat's upkeep. This should include service checkpoints and repair histories.

Before selling, it is important to immerse yourself in current market research to understand what buyers are looking for. This knowledge will help you refine your selling strategy and highlight your boat's unique appeal. You can gather insights from recent sales in your category on boat trading platforms or through brokers' listings.

When it comes to determining the listing price, consider the base price of similar boats, plus any unique additions or upgrades, minus depreciation and repairs. It is also crucial to get the sales agreement and contract in writing, outlining the terms of the sale and the obligations of both parties. This should include a description of the boat and engine, the purchase price, and details about delivery and finalization of the sale.

Donating your boat

Donating your boat to a registered charity is another option if you no longer want it. Organisations like Boat Angel in the USA and LWSA in New Hampshire accept boat donations and provide you with the necessary legal paperwork for a tax deduction. Boat Angel uses boat donations to produce life-changing values-based children's books and animations, as well as uplifting media for teenagers. LWSA, on the other hand, focuses on supporting important programs for young people. By donating your boat, you can receive a tax write-off for the boat's full fair-market value while avoiding the hassles of selling.

Use a boat salvage yard

If your boat is still seaworthy, you can sell it or donate it to charity. If it is no longer seaworthy, you can dispose of it at a boat salvage yard.

Boat salvage yards are available in some areas of the U.S. They will take your old ship and dismantle it, selling off any parts that are still in working condition. They will also take care of removing hazardous fluids and disposing of the fiberglass body.

However, the cross-linking of polyester and fiberglass in boat hulls makes them extremely strong, which also makes it very difficult to separate the components for recycling. While the fiberglass could be shredded and used as filler, this is not an ideal solution.

In some cases, the only option is to send a boat to a landfill. However, regulatory restrictions in Europe have made this practice illegal in some countries, encouraging the development of alternative solutions. For example, in Germany, used giant turbine blades are shredded and burned in cement kilns as an alternative to burning fossil fuels.

In the U.S., Rhode Island has launched a pilot project called the Rhode Island Fiberglass Vessel Recycling (RIFVR) Program, which collects dead boats, strips them of valuable materials, and crushes and shreds the remaining fiberglass hulls for use in cement kilns.

Reuse or downcycle fiberglass composites

The recycling of fiberglass composites is challenging due to the unique characteristics of the material. Fiberglass, often referred to as Fiber Reinforced Polymer (FRP) or glass-reinforced plastic (GRP), is a composite of two chemically bonded materials: reinforcing fibres and plastic. The process of recycling it involves addressing both components simultaneously while accounting for their distinct qualities.

One method of reusing or downcycling fiberglass composites is mechanical recycling, which involves breaking down the FRP into small pieces or powder. This technique was employed in the Rhode Island Fiberglass Vessel Recycling (RIFVR) program, where ground fiberglass from boat parts was processed into approximately 2-inch (50mm) pieces for utilisation in a cement kiln. This approach is advantageous as it is relatively simple and allows for the utilisation of 100% of the waste material. However, one drawback is that the resulting glass fibres are shortened, rendering them unsuitable for high-strength applications.

Another approach is thermal recycling, which includes processes such as pyrolysis. In pyrolysis, the fiberglass is heated to a sufficient temperature to transform the organic compounds in the plastic into gas. This gas, similar to natural gas, can be collected and refined to produce fuel. The oil extracted during this process can be blended with other types of fuel oil. While this method effectively recycles the plastic component of FRP, it leaves behind the fibres, which can be separately recovered and reused.

Chemical recycling is another viable option for dealing with fiberglass composites. This process involves dissolving the polymeric matrix of the composite using chemical solutions such as acids, bases, or solvents. This approach has been explored in the wind energy sector, where wind turbine blades made of composite materials can be recycled with higher efficiency through chemical processes.

While the recycling of fiberglass composites presents challenges, the development of new technologies and collaborative efforts between industries is leading to advancements in this field. These methods provide environmentally friendly alternatives to landfill disposal, which has been the predominant strategy for dealing with fiberglass waste.

Use as fuel for the cement industry

The end-of-life disposal of fiberglass boats is a complex issue. Boats, unlike cars, were not designed with disposal in mind, and the cross-linking of polyester and fiberglass in boat hulls makes them extremely durable but very difficult to recycle. Most boats from the past 50 years were constructed using fiberglass, and many of these are now reaching the end of their lives. As a result, old boats are piling up in harbors, backyards, boatyards, and landfills.

The issue of fiberglass boat disposal was discussed as part of the London Convention and London Protocol in 2016, which led to the International Maritime Organization (IMO) commissioning a study to review options for boat disposal and recycling. The report, published in 2019, highlighted that there is currently no viable financial market for recycled boat materials as they are not particularly useful or valuable. This means that, in most countries, including the US, fiberglass boats usually end up in landfills.

However, there are alternative disposal methods available, and these are becoming more common where regulatory pressure prohibits landfilling. For example, some areas of the US have boat recycling and disposal programs. California's Vessel Turn-In Program allows boat owners to turn in their boats to a local agency for proper disposal. Some marinas also have boat salvage yards that will take old boats, dismantle them, sell off any working parts, and dispose of the hazardous fluids and fiberglass body.

One innovative approach to fiberglass boat disposal is to use the ground-up material as fuel for cement kilns. In 2019, the Rhode Island Sea Grant and RIMTA completed a pilot project that examined and verified the viability of using ground fiberglass boat hull material in cement-kiln co-processing. This method has the potential to reduce the number of abandoned fiberglass boats and provide an alternative fuel source for the cement industry.

Cut out panels from old boats to reuse

If you're looking to cut out panels from old boats for reuse, there are a few things to keep in mind. Firstly, it's important to assess the condition of the boat and determine if it is still seaworthy. If the boat is in good condition, you may consider selling or donating it instead of cutting it up for parts.

Now, if the boat is no longer seaworthy and you're set on cutting out panels for reuse, you'll need the right tools and safety gear. This includes power tools such as a grinder, cutting equipment, and protective gear like gloves and eye protection. It is also important to work in a well-ventilated area or outdoors to avoid inhaling any dust or fumes.

The process of cutting out panels can vary depending on the boat's construction and the condition of the panels. In some cases, you may need to remove glued or fastened components to access the panels. Be careful when working with old boats as they may contain hazardous materials like lead paint or asbestos, which require special handling and disposal.

Once you've gained access to the panels, use a pattern or template to cut them out cleanly. You can use the old panels as a pattern or create a new one, depending on your desired outcome. Take precise measurements and mark the cut lines clearly to ensure an accurate fit for the new panels.

After cutting out the panels, you can choose to reuse them in your current project or find another application. Old boat panels can be reused in various ways, such as creating new furniture, artwork, or even building materials. With some creativity and craftsmanship, you can give these old panels a second life.
