Jacking up a fiberglass boat is a task that many boaters will have to do at some point. It is important to know the safest and easiest way to do this. The process involves blocking the boat on a hard, level surface, removing straps and covers, and placing jacks and jack stands to lift the boat. The boat should be lifted evenly on both sides, with support blocks placed under the strut along the center. The trailer can then be pulled out, and the boat lowered onto blocks and stands. This allows for maintenance such as trailer repairs, cleaning, or painting to be carried out.

What You'll Learn
Use jack stands to lift the boat
To use jack stands to lift a fiberglass boat, follow these steps:
First, ensure you have the right tools and a partner to assist you. Place the boat on a hard, level surface, such as plywood, especially if the ground is soft or made of asphalt, to prevent the stands from sinking and causing collapse. Block the wheels of the trailer to prevent any movement. If the boat is covered, remove the cover and undo the straps to clear the way.
Next, place the jack stands on either side of the boat under the transom, ensuring they are properly positioned so they don't push through the hull. Raise the jacks evenly and simultaneously with your partner to lift the boat. You want to lift it high enough to see a small space between the hull and the boat trailer bunks. As you raise the boat, build up support blocks below the strut along the center of the boat.
Once the boat is slightly higher than needed, place blocks in the center to bear the weight, and then lower the boat slightly so the blocks take the weight while the stands balance and support the boat. Now, place additional jack stands on the port and starboard sides to further stabilize the boat. Tap the bottom of the hull with a small hammer to identify supported areas, which are stronger than non-supported areas, and mark these areas with masking tape. These marked areas are where you will place the hydraulic jack to lift the boat.
Finally, place a hydraulic jack under the center of the hull, using a piece of wood to protect the hull, and jack up the boat until it lifts above the bunk carpet runners. You can now remove the wood from the tires and slowly pull the trailer out. Stop before reaching the first support crossmember to prevent knocking out the hydraulic jack. Place a second hydraulic jack, then remove the first one, and continue pulling the trailer out.

Positioning the boat on a hard, level surface
Firstly, choose a suitable location with a hard, level surface. This could be a garage floor, asphalt driveway, or a boat ramp. If you're using an asphalt driveway, it's important to place plywood sheets, such as 5/8" plywood cut into 2' x 2' sections, to prevent the stands from digging into the asphalt, especially during hot weather.
Next, carefully position the boat on the chosen surface. Ensure that the boat is securely blocked or chocked to prevent any unintentional movement. You can use wooden blocks or concrete blocks with wood on top for this purpose. Place the blocks at the rear of the boat, under the transom, and make sure they are solid and stable.
Before jacking, it's crucial to identify the supported areas of the hull, as these are stronger and safer for blocking. Use a small hammer to gently tap the length of the bottom of the hull, listening for different sounds. You'll hear a high-pitched sound in the hollow areas and a dull sound in the presence of a support or bulkhead. Outline these supported areas with masking tape, as these are the safe zones for placing the jack.
Now, you can proceed to place a small hydraulic jack, with a protective piece of wood to prevent damage to the hull, below the center of the transom. Position the jack within the outlined safe zones on the hull. At this point, you're ready to start jacking up the boat.
Remember, always exercise extreme caution when jacking up a boat. Ensure that the boat is securely blocked, and never leave the majority of the weight on jack stands or side supports. It's crucial to use a combination of blocking methods, such as wooden cribbing or timber stacks, to distribute the weight safely. By following these steps, you can effectively position the fiberglass boat on a hard, level surface before proceeding with the jacking process.

Using a bottle jack
Jacking up a fiberglass boat with a bottle jack is a delicate operation and should be done with caution. Here is a step-by-step guide on how to do it safely:
Firstly, lower the front of the trailer as close to the ground as possible. This can be done by lowering the tongue of the trailer. It is important to ensure the trailer is secure and will not roll or shift during the process. Once the trailer is lowered, place jack stands under the transom, or rear, of the boat. These jack stands will bear the weight of the boat, so ensure they are placed on a stable surface and are able to handle the load.
Next, you can begin to use the bottle jack. Place a piece of wood, such as a 4x4 or 6x6 timber, under the keel, towards the front of the boat. The wood will help distribute the load and protect the keel. Place the bottle jack on the wood, centred along the keel. Operate the bottle jack to begin lifting the front of the boat. Ensure the bottle jack is on level ground and stable.
Once the front is raised, you can now reposition the jack stands from the rear of the boat to the front. This will support the boat while you lower the rear. After the rear is lowered, you can now move the bottle jack to the rear, placing it on a piece of wood under the keel. Operate the bottle jack to raise the rear of the boat. With the front supported by the jack stands and the rear raised by the bottle jack, you can now remove the trailer.
It is important to note that bottle jacks have a small footprint and a very small point of contact with the wood, which can make them unstable. Therefore, it is crucial to use jack stands to support the majority of the weight and always have a helper to spot you during the process. Additionally, always ensure that no one is under the boat when it is jacked up, and be cautious when working underneath.

Removing the trailer
First, ensure the boat is secure and cannot move. Place blocks in front of the trailer wheels to prevent it from rolling forward. If your boat is covered, remove the cover and any strapping that is connected to the trailer.
Next, position your hydraulic jack. Place a small hydraulic jack under the centre of the hull, using a piece of wood to protect the hull while jacking up the boat. You want to jack up the boat enough to create a small space between the hull and the trailer bunks.
Now, place boat stands on the port and starboard sides. Ensure these are supported with blocks. You can then release the hydraulic jack and place wooden blocks in its place. The weight of the boat should now be sitting on the centre blocks, with the boat stands providing balance and support.
At this point, you can carefully and slowly pull out the trailer. You may need to jack up the front of the boat to create enough clearance to remove the trailer. Once the trailer is out, you can adjust the blocking to move it as far forward as possible. Do this by raising the boat stands, sliding the blocks into position, and then lowering the stands again.
It is important to work slowly and carefully when removing the trailer from a boat. This task has safety risks, so consider finding an experienced friend to help you.

Placing the boat on wooden blocks
When placing a boat on wooden blocks, it is important to follow safety precautions and use the correct tools. First, ensure the boat is on a hard, level surface. If using a soft surface like dirt or asphalt, place plywood underneath to prevent the stands from sinking into the ground and risking collapse. Additionally, block the trailer wheels to prevent any accidental movement.
Next, place a small hydraulic jack with a wooden board attached underneath the centre of the transom to protect the hull. Jack up the boat until you observe a gap between the hull and the bunk carpet support runners. At this point, you can remove any wood from the tires. Now, pull the trailer out slowly until you reach the first support crossmember, then stop. Get a second hydraulic jack and place it behind the crossmember, then jack it up to release the first jack.
Pull the trailer forward again until the rear axle is almost at the second jack. Place boat stands on the port and starboard sides, ensuring they are snug and secure. Release the hydraulic jack and put wooden blocks in place. Then, lower the side boat stands until the boat's weight is resting on the wooden blocks. Ensure the majority of the boat's weight is on the centre blocks, with the boat stands providing balance and support.
Finally, tap the hull's bottom with a small hammer, listening for hollow and dull sounds to indicate unsupported and supported areas, respectively. Outline the supported areas with masking tape as these are the stronger points where the hydraulic jack can be placed to lift the boat further.
