Worried about your favorite, hard-earned Alumacraft getting nasty mold and that musty smell?

The good news here is that you can stop it before it starts, with the right high-quality Alumacraft boat covers

In this blog post, we are going to discuss mold and water damage start, why it’s such a threat to boats, and what features to look for in boat covers that truly protect your investment.

So, keep reading!


What Causes Mold and Water Damage in Boats?


The first thing that comes to mind after hearing about mold and water damage is, Why does this happen? This is because mold and mildew just love damp, closed-up places, and boats have plenty of those. Even if you don't see puddles, just humid air can start mold growing on carpets, seats, in storage areas, and under cushions.

Here are the usual suspects that cause this problem:


  • Rain or melting snow sitting on your boat.
  • Condensation (like sweat) building up under a cheap or poorly vented cover.
  • Not enough air moving around, especially when your boat is stored.
  • Poor drainage, letting water sit inside the boat or on the seats.


If you let moisture problems go, they can lead to:


  • Bad smells
  • Ugly stains
  • Rotting parts inside your boat
  • Rusty metal pieces
  • Your boat being worth less money if you try to sell it.


So, what's the best way to stop all this? Keep water from getting in, and make sure any moisture that does get trapped can easily get out.


How a Quality Boat Cover Prevents Moisture Damage


Now, what makes a boat cover truly protect your Alumacraft? It's really important to pick one that's made specifically for your boat's shape and model. Here's what you should look for:

Custom or Semi-Custom Fit


A good fit changes everything. If a cover is too loose, water can just sit and collect on it. But if it's too tight, air can't move around, which traps moisture. On the other hand, custom Alumacraft boat covers for your specific Alumacraft will hug its unique shape perfectly. This means you get full protection without any sneaky gaps.



Marine-Grade Fabric


Not just any random material can handle being out on the water. That’s why look for high-performance fabrics built for marine environments, such as:


  • Solution-dyed acrylics (you might know brands like Sunbrella®)
  • Polyester blends that have a waterproof coating
  • Breathable, UV-resistant fabrics


These types of fabrics are amazing because they keep water out, but still let any humidity from inside your boat escape. That's a huge factor in preventing mold from getting on your Alumacraft.

Ventilation Systems


Alumacraft covers with built-in vents help control the temperature and moisture levels underneath. This constant airflow is incredibly important, especially on hot, humid days or during long-term storage in cooler months.

Strong Seams and Secure Tie-Downs


Look for seams that are double-stitched or heat-welded, as these are much less likely to leak. Also, make sure the tie-down straps are tough and durable. They need to keep the cover securely in place, even when strong winds or storms hit.

Support Poles or Frames


Using a support pole system helps prevent water from gathering on top of your cover. By raising the center of the cover slightly, rain and snow just slide right off instead of collecting and soaking through the material.

Tips for Mold Prevention Before Covering Your Boat

Even the best boat cover can't do its job if you've already sealed moisture inside. So, before you put the cover on your Alumacraft, here are a few simple steps to get it ready:

  • Clean and dry the inside completely, especially any carpet or fabric areas.
  • Open all compartments and let them dry out fully.
  • Take out any gear that might hold moisture or grow mold over time.
  • Put moisture absorbers (like desiccant packs) inside your boat.
  • Use mildew-resistant sprays on any spots where mold tends to grow.


Remember, keeping your boat dry during storage and using a cover that lets it breathe is your best defense against mold.
