Why Pontoon Boat Storage Blocks Are Necessary

From my own experience, using pontoon boat storage blocks has been a game-changer for maintaining my boat’s condition. These blocks provide a stable and secure platform that keeps the boat off the ground, preventing damage to the hull that can happen if it rests directly on uneven or rough surfaces. Without proper support, the weight of the boat can cause stress points that lead to warping or dents over time.

I’ve also found that storage blocks make it much easier to work on my pontoon during maintenance. Elevating the boat gives me better access underneath, so I can inspect and clean areas that would otherwise be hard to reach. Plus, keeping the boat elevated helps with air circulation, reducing the risk of moisture buildup and corrosion, which is crucial for extending the life of my vessel.

Overall, pontoon boat storage blocks are a simple investment that protects my boat, makes upkeep more convenient, and ultimately saves me money by preventing costly repairs. From my perspective, they’re an essential part of responsible boat ownership.

My Buying Guides on Pontoon Boat Storage Blocks

When it comes to storing my pontoon boat safely and securely, choosing the right storage blocks is essential. Over time, I’ve learned what features matter most and what to avoid. Here’s my detailed guide to help you pick the best pontoon boat storage blocks for your needs.

Why Pontoon Boat Storage Blocks Are Important

I quickly realized that proper storage blocks prevent damage to my boat’s pontoons while it’s out of the water. They keep the boat stable, distribute weight evenly, and protect the hull from scratches and warping. Without sturdy blocks, my boat could shift or even suffer costly damage during storage.

Key Factors I Considered When Buying Storage Blocks

1. Weight Capacity

One of the first things I checked was the weight capacity of the blocks. My pontoon boat is quite heavy, so I needed blocks that could support the full weight without cracking or compressing. Always choose blocks rated for more than your boat’s weight for extra safety.

2. Material Durability

I looked for blocks made from durable materials like high-density polyethylene (HDPE) or solid hardwood. These materials resist moisture, rot, and weathering, which is important since the blocks are often stored outside. Avoid soft woods or cheap plastics that degrade quickly.

3. Size and Shape

The size and shape of the blocks matter a lot. I picked blocks wide and tall enough to support the pontoon’s cylindrical shape evenly. Some blocks have grooves or cutouts designed specifically for pontoons, which help prevent slipping. Make sure the blocks fit the diameter of your pontoons comfortably.

4. Stability and Anti-Slip Features

I found blocks with rubberized or textured surfaces helpful because they keep the boat from sliding off. Stability is key since I store my boat on uneven ground sometimes. Blocks with a broad base also reduce the chance of tipping.

5. Ease of Handling and Storage

Since I sometimes need to move the blocks around, I chose ones that were not too heavy but still robust. Some blocks have built-in handles or are stackable, which makes storage more convenient when not in use.

Types of Pontoon Boat Storage Blocks I’ve Used

  • Plastic Storage Blocks: Lightweight and weather-resistant. Great for easy handling but be sure they’re thick and dense enough to support your boat.
  • Wooden Storage Blocks: Usually hardwood like oak or maple. Very sturdy but heavier and need occasional maintenance to avoid rot.
  • Rubber-Coated Blocks: Provide extra grip and reduce damage risks. I found these especially useful on slippery or uneven surfaces.

Tips From My Experience

  • Always place the blocks on firm, level ground to prevent shifting.
  • Use multiple blocks under each pontoon to distribute weight evenly.
  • Inspect your blocks regularly for cracks or wear, especially if you store your boat outdoors year-round.
  • Consider getting adjustable stands if you want more versatility in storage height.

Final Thoughts

Choosing the right pontoon boat storage blocks made a big difference in how secure and protected my boat feels during storage. By focusing on weight capacity, material, and stability, I found blocks that keep my pontoon safe and make storage hassle-free. I hope my experience helps you find the perfect blocks for your boat!
