Why Pontoon Boat Storage Blocks Are Necessary
From my experience, pontoon boat storage blocks are absolutely essential for keeping my boat safe and in good shape when it’s out of the water. Without proper support, the boat’s weight isn’t evenly distributed, which can cause damage to the pontoons or the frame over time. Using storage blocks helps prevent warping, dents, or cracks that could lead to costly repairs later on.
I’ve also found that these blocks make maintenance much easier. When my pontoon boat is securely elevated on storage blocks, I can access the underside for cleaning, inspections, or repairs without hassle. This not only saves me time but also helps me catch any potential issues early before they become serious problems.
Lastly, storing my boat on proper blocks protects it from moisture buildup and ground contact, which can cause rust or mildew. It’s a simple investment that preserves the longevity and value of my pontoon boat, giving me peace of mind every time I put it away for the season.
My Buying Guide on ‘Pontoon Boat Storage Blocks’
When I first started looking for pontoon boat storage blocks, I quickly realized there are quite a few factors to consider to keep my boat safe and stable during storage. Here’s what I’ve learned through my own experience, which might help you find the right storage blocks for your pontoon.
Understanding Pontoon Boat Storage Blocks
Pontoon boat storage blocks are essential for keeping your boat elevated and stable when it’s not in the water. They prevent damage to the hull and frame by distributing the boat’s weight evenly. I found that choosing the right blocks can make a big difference in protecting my investment.
Material Matters: Wood vs. Plastic vs. Rubber
From my research and usage, I discovered that storage blocks come in different materials:
- Wooden blocks: Traditional and affordable, but they can rot or weaken over time if exposed to moisture. I made sure to choose treated wood to avoid this issue.
- Plastic blocks: Lightweight, durable, and weather-resistant. They don’t absorb water and last longer, which I appreciated during wet seasons.
- Rubber blocks: Provide excellent grip and cushioning but tend to be pricier. I used rubber blocks for added protection on sensitive parts of my pontoon.
Size and Weight Capacity
One of the first things I checked was the size and weight rating of the blocks. My pontoon boat is quite heavy, so I needed blocks that could support the full weight without cracking or sinking. I always recommend checking the manufacturer’s specifications and opting for blocks with a higher weight capacity than your boat’s actual weight for extra safety.
Stability and Safety Features
I paid close attention to the shape and surface of the blocks. Some blocks have notches or grooves that help hold the pontoons in place and prevent slipping. Stability is crucial, especially if you live in a windy area or store your boat outside. Blocks with a non-slip surface gave me peace of mind.
Ease of Use and Portability
Since I often move my boat around my property, I preferred storage blocks that were easy to carry and position. Lightweight plastic blocks were much easier to handle compared to heavy wooden ones. Some even have handles or stackable designs, which made storage and transport more convenient.
Price and Longevity
Balancing cost and durability was important for me. Cheaper blocks might save money upfront but may need replacement sooner. I found investing a bit more in high-quality blocks saved me time and hassle in the long run. Consider how often you’ll use them and the storage conditions to decide what fits your budget.
Final Tips from My Experience
- Always use multiple blocks to distribute weight evenly.
- Place blocks on a firm, level surface to prevent shifting.
- Regularly inspect your blocks for wear and replace them if you see cracks or damage.
- If storing your pontoon for a long time, consider covering the blocks to protect them from weathering.
By keeping these points in mind, I was able to choose pontoon boat storage blocks that keep my boat safe and stable year-round. I hope my guide helps you find the perfect fit for your pontoon too!
