Screen printed plywood or anodized aluminum? Which shelf provides the best torsional rigidity, dampens impact noise when fishing for zander and remains dimensionally stable for years.

Petri Hail and greetings by the water! For predatory fish and carp anglers, the inflatable boat is the epitome of flexibility, independence and direct access to untouched water areas. But while many anglers spend days discussing engines, depth sounders or bait colors, the actual foundation of the boat is often neglected: the shelf.

Anyone who has ever tried to safely net a pike while standing on a flexible slatted frame or has observed how the hull arches under load while gliding knows that the floor determines safety, ergonomics and driving dynamics. If you're looking for modern, robust inflatable boats for fishing When it comes to fixed shelves, you'll find two dominant materials: waterproof marine plywood (screen printing) and extruded aluminum. But which floor really suits your needs?

"The bottom of the boat is your daily workplace on the water. It decides whether you maneuver silently at the spot or whether you scare away cautious predatory fish from a long distance with metallic impact noise."

1. Why a fixed shelf is mandatory for boat anglers

Before we compare wood and aluminum in detail, it's worth taking a look at slatted floors and high-pressure air floors (drop stitch). A simple slatted floor is only enough for feeding. It lacks the necessary longitudinal rigidity for hours of active spin fishing while standing.

High-pressure air bases score points with their small pack size, but pose risks in tough everyday fishing: falling treble hooks, sharp jig heads or filleting knives can damage the high-pressure chamber. In addition, air floors bend under load with strong engines.

A fixed shelf - whether made of wood or aluminum - is clamped into the hose body without play using side aluminum stringers. This creates a stiff hull that resists choppy waves and protects your boat from the inside against sharp objects.

2. The wooden floor (screen printing panel) in the practical check

Wooden floors for quality inflatable boats are made of multi-glued marine plywood (birch or okoumé) that is heat-sealed with phenolic resin. The top has a non-slip sieve structure, while the bottom lies smoothly against the PVC floor.

The strengths of the wooden floor:

• Excellent sound insulation (impact sound): Wood has an organic fiber structure that absorbs shocks. If a pair of pliers or a 30-gram lead head slips out of your hand, all you hear is a dull clacking sound. For zander and predator anglers in shallower areas, this is an invaluable advantage over bright-sounding metal bottoms.
• Pleasant feel and temperature insulation: Wood naturally insulates. In the cool late autumn, the cold of the water does not immediately penetrate the soles of your boots. The plate does heat up in summer, but remains noticeably more bearable than hot metal, even barefoot or for boat dogs.
• High grip in wet conditions: The screen-printed surface provides reliable support, even if the deck gets wet from rain or fish slime.
• Easy Editing: Holders for battery boxes, lashing eyes or seat bases can be easily installed using wood screws and Sikaflex.

The weaknesses of wooden floors:

• Moisture in deep scratches: If damaged cut edges are left in bilge water for weeks, the wood can swell.
• Higher weight: A 12 mm screen printing plate weighs around 10 to 15 percent more than an aluminum hollow chamber floor.
• Maintenance effort: Wooden floors should be kept dry over the winter and scratches should occasionally be resealed with boat varnish.

3. The aluminum floor in the practical check

Aluminum floors consist of milled hollow chamber profiles made of anodized marine aluminum, which are connected via tongue and groove systems and braced via side stringers.

The strengths of the aluminum floor:

• Maximum torsional stiffness: Aluminum does not give in under load. Anyone traveling with 15 to 20 HP will experience optimal torso guidance. In our range for powerful boats and outboards It turns out that aluminum floors bring the engine power directly into the water without any loss of damping.
• Rot-proof and indestructible: Water, UV radiation or gasoline residues cannot harm aluminum. Even leaving water in the boat for days does not cause it to swell.
• Low segment weight: The hollow chamber profiles make it easier to carry the individual segments when loading and unloading.

The weaknesses of the aluminum floor:

• Structure-borne sound transmission (gong effect): Aluminum transmits kicks and falling tackle as sound waves directly into the water. The only solution here is additional EVA mats.
• Strong temperature conductors: In midsummer the panels heat up to over 50 °C in the sun; In late autumn and winter they quickly absorb the heat from your feet.
• More slippery when there is frost or mucus: When the ground freezes or comes into contact with fish slime, grooved metal becomes smoother than screen-printed wood.

In addition to the bottom, the underwater guidance also plays a key role in course stability and gliding behavior. Read our guide: Inflatable keel in an inflatable boat: Is it worth retrofitting under the wooden floor?

5. Practical tip: Install stringers using the paddle trick

When setting up both systems, the aluminum stringers often get jammed due to the hose pressure. With this simple step it works in two minutes:

1. Only fill hoses to 30%: This keeps the boat flexible enough for the plate edges.
2. Form roof shape: Lay the bow and stern plates flat and place the middle plates against each other like an inverted V.
3. Paddle underneath: Slide an aluminum paddle under the fuselage from the outside to raise the edges.
4. Attach and latch the stringer: Attach the stringer and carefully step onto the center of the roof until the panels click into place.

Conclusion: Which bottom suits your fishing style?

The Wooden floor (screen printing) is ideal for spin fishermen, vertical anglers and predator hunters. Those who fish in shallow areas benefit from the superior sound insulation. In addition, the pleasant thermals protect against cold feet in the cool autumn.

The Aluminum floor is the favorite for frequent drivers and trailer owners. If you are looking for a maintenance-free deck that can be permanently outdoors and requires maximum rigidity when gliding with powerful engines, choose aluminum.
