The Zodiac Cadet lineup isn't three sizes of the same boat. The Aero, Alu, and RIB Alu are built around three different design priorities, and choosing the wrong one means lugging unnecessary weight aboard your yacht or settling for a boat that can't keep pace with how you actually use it.

All three share the same Zodiac foundation: welded PVC tubes, self-bailing systems, and a five-year structural warranty. What separates them is the floor and hull, and that single decision drives everything else, performance, stowage, and the outboard you pair it with.

By the end of this guide, you'll know exactly which Cadet fits your boat, your crew, and your conditions.

The Zodiac Cadet Aero: Portability First

The Zodiac Cadet Aero: Portability First | Annapolis Inflatables

The Zodiac Cadet Aero is built for one job above all others: getting on and off a boat without taking over the deck. Its Aerotech inflatable air floor is the defining feature, when you deflate it, the entire boat collapses into a carry bag compact enough to slide into a cockpit locker or strap to a foredeck.

Who Zodiac Cadet Aero Is For

Sailors, cruisers, and anyone who needs a tender that stows without drama. If your mothership is a sailboat or catamaran with limited deck space, or if you're doing coastal passages where everything aboard needs to be secured and out of the way, the Zodiac Cadet Aero is the right starting point.

Hull and Floor

The air deck floor inflates firm underfoot and provides a comfortable, flexible ride. It is noticeably lighter than a solid panel aluminum floor and packs down completely, there are no rigid panels to wrestle with. The trade-off is that the inflatable floor is softer than aluminum under load and will flex more at speed compared to either the Alu or RIB Alu.

Key Spec

  • Length: 10'2" | Beam: 5'1" | Weight: 78 lbs
  • Capacity: 5 persons / 1,257 lbs
  • Max motor: 10 HP (manufacturer recommends 8 HP)
  • Stowed: 3'9" x 1'11" x 1'1"
  • Fabric: PVC, Zodiac 1100 Decitex (welded seam)
  • Warranty: 5 years on structure

The full range runs from the 200 Aero (6'7", 52 lbs, up to 3 HP) through to the 350 Aero (11'6", 103 lbs, up to 15 HP), five models that scale with the size of your mothership.

Motor Pairing for Zodiac Cadet Aero

Electric: The ePropulsion eLite suits the smaller Aero models (200 and 230), at just 14.7 lbs, it stows alongside the deflated boat without adding bulk. For the 270 through 350 Aero, the Torqeedo Travel S is the better fit, with 3 HP equivalent output and a click-and-play battery system built for tenders up to 1.5 tons.

Gas: The Tohatsu MFS3.5C suits the smallest models. For the 270 and 310 Aero, the Yamaha F6 or Tohatsu MFS4D are the right call, lightweight 4-strokes that stay within the Aero's rated HP ceiling without overloading the transom.

The Zodiac Cadet Alu: The All-Rounder

The Zodiac Cadet Alu: The All-Rounder | Annapolis Inflatables

The Zodiac Cadet Alu steps up from the Aero by swapping the inflatable floor for a solid aluminum solid panel floor. That floor change adds meaningful stiffness underfoot, improves stability when you're moving around the boat, and enables a higher max HP rating across the range, without pushing the weight or cost into RIB territory.

Who Zodiac Cadet Alu is For

Mixed-use buyers who want more from their tender than a simple shuttle. If you fish from your inflatable, carry gear to shore regularly, bring multiple adults aboard, or need a secondary boat that can handle a wider range of conditions, the Alu is the practical choice. It also works well as a standalone runabout for lake or calm inshore use.

Hull and Floor

The solid aluminum panel floor (with wood bow board) snaps into place and creates a noticeably firmer platform than the Aero's air deck. It does not deflate, so the Alu is heavier to stow and takes up more space when packed. But it sets up quickly and offers a more confident, stable feel for everyday use.

Key Specs

  • Length: 10'2" | Beam: 5'1" | Weight: 109 lbs
  • Capacity: 5 persons / 1,323 lbs
  • Max motor: 15 HP (manufacturer recommends 10 HP)
  • Fabric: PVC, Zodiac 1100 Decitex (welded seam)
  • Warranty: 5 years on structure

The Alu range runs from the 270 (8'10", approx. 101 lbs, up to 8 HP) to the 350 (11'6", approx. 143 lbs, up to 20 HP), three models covering the most common tender and utility boat sizes.

Motor Pairing

The Yamaha F8 or Tohatsu MFS9.8C sit comfortably within the recommended HP range for the 270 and 310 Alu. On the 350 Alu, where the ceiling rises to 20 HP, the Yamaha F15 or Tohatsu MFS15E give you the headroom to carry a full crew at pace.

The Zodiac Cadet RIB Alu: Performance and Stability

The Zodiac Cadet RIB Alu: Performance and Stability | Annapolis Inflatables

The Zodiac Cadet RIB Alu is a different class of boat. While the Aero and Alu are both inflatable-floor tenders, the RIB Alu is a true rigid inflatable boat, it has a marine-grade 5052 aluminum hull with a full-length keel guard, white AkzoNobel coating, and non-skid cockpit strips. The tube set sits on top of that rigid hull rather than making up the floor.

Who Zodiac Cadet RIB Alu is For

Buyers who want RIB performance in a compact, manageable package. If you regularly operate in chop, need to plane with a full crew, use davits for launching and recovery, or simply want the most capable and durable option in the Cadet lineup, the RIB Alu delivers that, at the cost of the ability to pack it away.

Hull and Floor

The rigid aluminum hull is the Zodiac Cadet RIB Alu's core advantage. It tracks better at speed than either the Aero or Alu, handles chop with greater confidence, and planes more easily with equivalent power. Zodiac's patented FUTURA hull design underpins the RIB Alu's performance geometry. The hull also incorporates integrated davit lifting points (three and four-point lift systems), practical for larger mother ships with davit systems.

What you give up is packability. The rigid hull does not fold, deflate, or collapse. It stows on a set of davits, on a trailer, or on deck, but not in a locker.

Key Specs

  • Length: 9'0" | Beam: 5'6" | Weight: 84 lbs
  • Capacity: 4 persons / 873 lbs
  • Max motor: 10 HP (manufacturer recommends 8 HP)
  • Tube diameter: 16"
  • Fabric: German Haku PVC (welded seam)
  • Stowed: 6'11" x 3'11" x 1'8" (rigid, does not compress further)
  • Warranty: 5 years on structure

The RIB Alu range spans five models from the 240 (8'0", 84 lbs, up to 6 HP) through to the 360 (11'11", 110 lbs, up to 30 HP), a wider HP ceiling than either the Aero or Alu, reflecting the hull's ability to handle significantly more power.

Motor Pairing

The Yamaha F15 or Tohatsu MFS15E are the strongest pairings for the 270 and 300 RIB Alu, both within the manufacturer-recommended HP range. On the 330 and 360 models, the Yamaha F20 or Tohatsu MFS20E are the natural step up to match the higher HP ceiling.

Which Zodiac Cadet Is Built for Your Boat?

Which Zodiac Cadet Is Built for Your Boat? Annapolis Inflatables

Scenario 1: The Yacht Tender Buyer → Cadet Aero

You sail a 38-foot sloop with limited deck real estate. Your tender needs to disappear when you're underway, into a locker, onto the foredeck, or below. You mostly use it to row or motor short distances to shore, carry two or three people, and bring back groceries or dive gear. You don't need it to plane. You need it to stow. The Cadet Aero deflates fully, fits in a carry bag, and weighs under 80 lbs for the most commonly sized models. That's the right boat.

Scenario 2: The Weekend Family or Fishing Buyer → Zodiac Cadet Alu

You're on a powerboat or larger cruiser, and you want a utility inflatable that can handle more than a quick run to the dock. You fish from it. You load it with coolers and gear. You put four or five people in it at once. You want a floor that doesn't flex underfoot and an HP rating that gives you some real performance without jumping to a full-size RIB. The Zodiac Cadet Alu's aluminum floor, higher capacity, and up-to-20-HP ceiling covers all of that, while still deflating and stowing when needed.

Scenario 3: The Performance or Coastal Use Buyer → Cadet RIB Alu

You operate on a larger vessel, motor yacht, expedition boat, or charter, with a davit system. You want a tender that planes quickly, handles harbor chop without complaint, and can be hoisted and deployed reliably. Packability is not a factor because it lives on the davits. What matters is a rigid hull, integrated lifting points, a wide HP range, and a boat that performs like a proper RIB rather than a soft-floor inflatable with an outboard. That's the Zodiac Cadet RIB Alu.

Final Verdict: Which Cadet Is Right for You?

The decision comes down to three questions: how much do you need to stow it, what are you putting in it, and what conditions do you operate in?

  • If stowage is your top priority and you'll mostly be running low HP, get the Cadet Aero. It is the lightest, most packable option in the range and the right call for any sailboat or cruiser with limited deck space.
  • If you need a firm floor, higher capacity, and more power without committing to a rigid hull, get the Zodiac Cadet Alu. It is the most versatile of the three and handles a wider range of everyday uses well.
  • If you have davits, want genuine planing performance, and operate in conditions where a soft floor tender won't cut it, get the Zodiac Cadet RIB Alu. It is the most capable boat in the Cadet line and the one that grows with your expectations of what a tender should do.

There is no wrong answer here as long as it matches how you actually use the boat. All three are well-made, well-supported, and backed by Zodiac's track record. The Aero, Alu, and RIB Alu are just different tools for different jobs, and the best one is the one that fits your mothership, your crew, and your water.

FAQs

What is the difference between the Zodiac Cadet Aero and Cadet Alu?

The core difference is the floor. The Cadet Aero has an inflatable air deck (Aerotech) that deflates completely, making the boat fully packable and significantly lighter. The Zodiac Cadet Alu has a solid aluminum solid panel floor that provides a firmer, more rigid platform but adds weight and means the floor panels must be removed and stowed separately.

Is the Zodiac Cadet RIB Alu worth the extra cost?

If you need a rigid hull, yes. The RIB Alu's marine-grade 5052 aluminum hull gives it a measurably different performance profile, it planes more easily, handles chop better, and supports higher HP ratings (up to 30 HP on the 360 model).

What size outboard does the Zodiac Cadet take?

It depends on the model. The Cadet Aero range accepts up to 3 HP (200 Aero) through 15 HP (350 Aero). The Zodiac Cadet Alu accepts up to 8 HP (270 Alu) through 20 HP (350 Alu). The Zodiac Cadet RIB Alu accepts up to 6 HP (240 RIB) through 30 HP (360 RIB).

Is the Zodiac Cadet a good yacht tender?

Yes, and specifically the Cadet Aero is designed with yacht tender use as its primary application. The inflatable floor allows it to pack down into a carry bag for passage-making, the welded PVC tubes are built for durability in saltwater, and the self-bailer handles spray and light rain without fuss.
