What Size Inflatable Boat Do I need?

Choosing an inflatable boat is not simply a matter of counting how many people you want to carry.

A boat can have enough rated capacity for you and still feel cramped once you add fishing gear, a chilly bin, fuel, safety equipment and everything else that inevitably comes along for the ride.

On the other hand, buying the biggest boat available might give you plenty of room on the water, but it can also create more work every time you need to inflate it, move it, wash it down and pack it away.

The right inflatable boat size depends on how you intend to use it, where you will store it and what you need it to do once you are on the water. You can also compare the full True Kit range before looking at the individual use cases below.

For most people, the best place to start is not:

How many people can this boat carry?

It is:

What will I use this boat for most often?

That one question will usually narrow the options down fairly quickly.

True Kit inflatable boat- Discovery - Size Range

Start With Your Main Use

A boat used primarily for fishing has very different requirements from a compact yacht tender.

An angler might spend an entire day aboard with rods, tackle, an anchor, a motor, fuel or batteries, food and safety equipment. Technically fitting everything aboard is one thing. Having enough space to cast, move around and land a fish without standing on your lunch is another.

A yacht owner using a tender for short trips between an anchored boat and shore may care far more about low weight, quick handling and whether the tender fits neatly across the transom or on the foredeck.

Someone travelling with a caravan, campervan or 4WD may want the largest practical boat they can still pack into the vehicle and launch without towing a trailer halfway around Australia.

Before comparing dimensions, decide which of these sounds most like you:

Fishing is the main priority
Exploring beaches, rivers, lakes or sheltered coastline
Travelling with a caravan, campervan or 4WD
Carrying a boat aboard a yacht
Making short tender trips between a larger boat and shore
General family boating
Keeping a compact rowing boat or emergency backup aboard

You may want your boat to do several of these jobs. Most people do. The important thing is identifying the job it will perform most often, rather than choosing around the occasional trip you might make once or twice a year.

Does the Boat Need to Stay Inflated?

How you plan to store the boat is one of the most important parts of choosing its size.

A boat that stays inflated for most of the season presents a very different decision from one that needs to go back into its bag after every outing.

Keeping the boat inflated

When a boat will remain inflated, the limiting factor is often its full external dimensions rather than its packed size.

For a yacht tender, consider:

The width of the yacht’s transom
The available space on the foredeck
Whether the boat will obstruct hatches or deck equipment
How the tender will be lifted
Where it will be secured during passages
Whether it can be launched and recovered safely by the usual crew

True Kit boats are exceptionally light for their size, but lightweight does not necessarily mean effortless. A tender can still be awkward to manage if it is physically too large for the available deck space, davits or lifting arrangement.

Measure the area where the tender will actually live before choosing a model. Do not rely only on the length of the yacht or assume that a larger foredeck will automatically accommodate a larger tender.

A few minutes with a tape measure now can prevent a fairly expensive game of inflatable Tetris later.

Packing the boat away after use

If you plan to deflate the boat after most trips, packed dimensions and setup effort become more important.

Every True Kit is designed to be folded and packed repeatedly, but a smaller model will still generally be quicker to handle, wash, dry and pack after a short trip.

The interesting part is that a larger inflatable boat does not always require dramatically more storage space.

For example, the Discovery 330 packs into a bag measuring approximately 105 × 70 × 35 cm. The considerably larger Discovery 400 packs into a bag measuring approximately 105 × 70 × 40 cm.

That additional five centimetres of packed depth gives you a boat that is 70 cm longer and 15 cm wider once inflated. The trade-off is handling weight: the Discovery 400 weighs approximately 45 kg, compared with 36 kg for the Discovery 330.

So, while the larger boat may fit into almost the same storage space, it will not necessarily be as easy for one person to move around.

That distinction matters. Packed volume determines whether the boat fits in your vehicle. Weight determines whether you are happy to pull it back out again next weekend.

How Much Space Do You Need on the Water?

Passenger capacity and usable space are not the same thing.

Rated capacity tells you the maximum permitted load. It does not tell you whether everyone will be comfortable once you add:

An outboard
Fuel or batteries
Fishing tackle
Rods
An anchor and rope
Food and water
Dive or camping equipment
Children
Dogs
Shopping or provisions
Safety equipment

All of this weight must be included when considering the boat’s capacity.

More importantly, bulky equipment takes up physical space even when it does not bring the boat anywhere near its maximum permitted load.

A chilly bin, tackle box and two excited dogs can occupy a surprising amount of boat.

Buyers primarily looking for family boating adventures should therefore allow for children, pets, bags and safety equipment rather than basing the decision on adult seating alone.

For occasional short trips ashore, a compact boat may be perfectly adequate. For full days spent fishing or exploring, additional floor space can be far more valuable than the headline capacity figure suggests.

What Size Inflatable Boat Is Best for Fishing?

When choosing a portable inflatable fishing boat, it usually makes sense to select a slightly larger model than the minimum needed to carry the anglers.

Fishing requires room to move, cast, land fish and manage equipment without rods, hooks and tackle constantly crossing over one another.

You may be able to fit two anglers into a compact boat, but that does not necessarily mean both anglers will enjoy fishing from it for eight hours.

A larger Discovery is generally the better choice when:

Two or more people regularly fish together
You carry several rods and a full tackle setup
You spend long days on the water
You want a larger petrol or electric outboard
You travel across larger lakes, estuaries or sheltered coastal waters
You need room for camping, diving or other equipment

Discovery Inflatable Boat Size Range

The Discovery 280

The Discovery 280 is the most compact model in the Discovery range.

At 280 cm long and 150 cm wide, it weighs approximately 31 kg, packs into a 100 × 65 × 35 cm bag and is rated for an outboard of up to 8 hp.

It provides a useful balance for buyers who want the open bow and versatility of a Discovery but still place a high priority on compact handling.

It is well suited to:

One or two-person fishing
Couples exploring from a vehicle or caravan
Family trips where storage is limited
Buyers who want more versatility than a dedicated tender
People who regularly need to inflate and pack the boat away

The Discovery 280 is a good fit when portability still sits near the top of your list. It gives you a genuine multipurpose boat without making every launch and pack-down feel like a major event.

Discovery 330

The Discovery 330 is often the strongest all-round choice for fishing, exploring and family use.

It is 330 cm long, has a 165 cm beam and supports an outboard of up to 15 hp. At approximately 36 kg, it remains considerably lighter and easier to transport than most rigid boats of a comparable usable size. Its packed bag measures approximately 105 × 70 × 35 cm.

It is a practical option for:

Two anglers and their equipment
Families wanting a multipurpose portable boat
Caravan and 4WD travel
Fishing, exploring and occasional tender use
Buyers wanting more motor capacity without moving to a four-metre boat

For many Australian and New Zealand buyers, this is the sweet spot.

It is compact enough to travel without a trailer, but large enough to carry two anglers, their equipment and everything needed for a proper day on the water. It can serve as a fishing boat one weekend, a family boat the next and an occasional tender when required.

If you want one portable boat to cover several jobs reasonably well, the Discovery 330 will often be the first model worth considering.

Discovery 400

The Discovery 400 is designed for buyers who prioritise space, load capacity and performance.

It is 400 cm long, 180 cm wide and rated for an outboard of up to 20 hp. The boat weighs approximately 45 kg and packs into a 105 × 70 × 40 cm bag.

It makes sense when:

Fishing space is a major priority
Several adults will regularly be aboard
You carry substantial camping, dive or fishing equipment
You want to use a more powerful outboard
The boat will often remain inflated
Two people are normally available to launch and recover it
You want the greatest versatility and onboard room

The important point is that the Discovery 400 occupies only slightly more packed space than the Discovery 330.

You are not sacrificing half the garage to gain the extra room. The more meaningful difference is handling the additional length and weight once the boat comes out of the bag.

For buyers already planning to transport the boat packed down in a large vehicle, caravan or motorhome, the Discovery 400 may therefore be more practical than its four-metre length initially suggests.

If the boat will be used for long fishing days, carrying several adults or transporting substantial equipment, the additional space can be worth far more than the modest increase in packed volume.

Tactician Boat Size

What About the Tactician?

Not every angler needs a wide, multipurpose Discovery.

The True Kit Tactician is a narrower, fishing-focused kayak alternative designed for reaching water that is difficult to access with a conventional boat and trailer.

The Tactician 350 is 350 cm long but only 115 cm wide. It weighs approximately 28 kg and packs into a bag measuring 80 × 60 × 25 cm. Despite its compact packed size, it has an aluminium transom rated for an outboard of up to 6 hp.

This makes it particularly useful for:

Solo anglers
Two-person fishing trips
Rivers, estuaries and remote lakes
Carrying a boat in a car boot, motorhome or yacht locker
Launching away from formal boat ramps
Buyers who prioritise access and compact storage over family capacity

Its catamaran hull also provides the stand-up stability needed for casting, moving around and landing fish.

A small electric outboard can provide incredibly efficient propulsion. A petrol outboard can also be used, with up to 6 hp available for anglers who need to cover more water.

Even a lower-powered motor can move the Tactician efficiently, while a short-shaft petrol outboard in the 3 to 6 hp range is the more appropriate option when planing performance is required.

Choose the Tactician when fishing is the absolute priority and you value compact transport and access to remote water.

It is for the angler who looks at a narrow track, an awkward shoreline or a lake without a proper ramp and thinks, “That looks worth exploring.”

Choose a Discovery when you need a wider, more multipurpose platform for fishing, family use and carrying larger amounts of equipment.

What Size Inflatable Boat Is Best as a Yacht Tender?

Choosing an inflatable yacht tender is usually driven by the space available aboard the main vessel and the number of people who regularly travel ashore.

You should also consider whether the tender will:

Stay inflated throughout the season
Sit across the transom
Be carried on davits
Be stored on the foredeck
Be deflated and placed in a locker
Be lifted by one person or several crew members
Carry shopping, fuel, water or other provisions back to the yacht

Tender buyers often focus on the maximum number of people they might occasionally carry. In reality, the more useful question is how many people will use it on an ordinary day.

There is little point in choosing a large tender for the one week each year when guests come aboard if it is awkward to launch and recover for the other 51 weeks.

Navigator Inflatable Boat Size Range

Navigator 250

The Navigator 250 is a compact yacht tender for couples, small crews and owners with limited storage space.

It is 250 cm long, weighs approximately 24 kg and packs into an 80 × 60 × 25 cm bag. It has a capacity of 350 kg and supports an outboard of up to 6 hp.

It is particularly suitable when:

One or two people normally use the tender
Low weight is a major priority
The boat needs to fit into a small locker
The tender is regularly lifted onto a deck or davits
Most trips are short runs between the yacht and shore

For a couple making regular trips from anchorage to shore, the Navigator 250 can be all the tender they need. It remains light enough to handle without turning every launch into a full-crew operation.

Navigator set to launch - Boat Size Range

Navigator 300

For a family or larger cruising crew, the Navigator 300 provides considerably more capacity and space while remaining portable.

It is 300 cm long, weighs approximately 31 kg and packs into a 105 × 60 × 30 cm bag. It carries up to 500 kg and supports an outboard of up to 10 hp.

It is often the better choice when:

Three or four people regularly travel together
You carry provisions, luggage or equipment
The tender will cover longer distances
You want greater motor capacity
The yacht has sufficient deck, transom or locker space

The Navigator 300 gives a family more breathing room, particularly once shopping bags, beach equipment or other cruising essentials are aboard.

For tender use, however, do not automatically choose the largest model your yacht can carry. A tender that is easy to launch and recover will usually be used more often than one that provides extra space but becomes a chore to handle.

Stowaway Boat Size

When Is a Stowaway the Better Choice?

Some owners do not need an outboard-powered tender at all.

The True Kit Stowaway is designed as a compact, human-powered boat for rowing between a yacht and shore, carrying in a motorhome or keeping aboard as a lightweight backup.

The Stowaway 250 is 250 cm long, weighs approximately 14 kg and packs into a bag measuring around 72 × 42 × 20 cm. It does not have a transom and is intended for human-powered use.

A Stowaway may be the right choice when:

Storage space is extremely limited
The boat is only needed for short rowing trips
You do not need an outboard
Low weight matters more than speed or range
You want a compact secondary or backup boat
You need something that is incredibly easy to lift aboard

At 14 kg, the Stowaway is the model you choose when simplicity matters more than horsepower. There is no motor, fuel tank or heavy battery to find space for. Unpack it, inflate it and row ashore.

It is not intended to replace a powered tender for longer trips, exposed anchorages or carrying substantial equipment. For short distances and simple transport, however, that lack of complexity is exactly the appeal.

Do You Need a Petrol or Electric Outboard?

Boat size and motor choice should be considered together.

A larger outboard can provide more speed and better performance under load, but it also adds:

Purchase cost
Weight
Fuel or battery storage
More work during setup
More equipment to transport
Greater lifting requirements

Mounted Outboard Motor on a True Kit Navigator

True Kit’s catamaran hulls are particularly well suited to electric outboards, because their efficient twin-hull design reduces unnecessary drag compared with many conventional inflatable dinghies.

That efficiency means you do not always need a large outboard to enjoy useful performance.

An electric outboard is worth considering when:

You fish on lakes or waterways with petrol-engine restrictions
You mainly cover short to moderate distances
You want simpler operation and maintenance
You can comfortably manage and recharge the battery
Minimising fumes and noise is important

Electric propulsion is particularly appealing for fishing, where quiet operation can be a genuine advantage rather than simply a nice feature.

A petrol outboard may be preferable when:

You need greater range
Higher speed is important
You regularly carry heavier loads
Charging access is limited
You use the boat for longer coastal or remote trips
You need to refuel quickly while travelling

Always follow the maximum outboard rating for the specific boat.

There is no benefit in choosing a motor that makes the complete setup too heavy or inconvenient to use regularly. The motor, fuel tank or battery must also fit inside the storage and handling limits that led you to choose a portable boat in the first place.

A portable boat paired with an outboard you hate lifting is only partly portable.

Should You Buy the Bigger Boat?

When choosing between two sizes, consider how often the advantages of the larger boat will outweigh the additional handling.

Size up when:

Fishing is your main use
Two or more adults regularly spend long days aboard
You carry significant equipment
You want a larger outboard
You have enough storage space
You normally launch with another person
The packed dimensions are manageable for your vehicle

Stay smaller when:

The boat must fit across a yacht transom or foredeck
You inflate and pack it away after every short trip
Storage is very limited
You need to carry the boat over a meaningful distance
Quick setup matters more than maximum space
Tender trips are short and lightly loaded
One person needs to lift or manage the boat

If both models fit inside your vehicle and the extra weight is manageable, sizing up can make sense, particularly for fishing and family use.

If the larger model turns every outing into a two-person job when you usually boat alone, the extra space may quickly lose its appeal.

The best boat is not necessarily the largest one you can afford. It is the largest boat you can store, transport, launch and use without creating unnecessary friction.

The boat that gets used most weekends is better than the bigger boat that stays in its bag.

Specifications should always be confirmed on the current product page before selecting a boat or outboard.

A Simple Way to Choose

If you mainly need a compact rowing tender, consider the Stowaway 250.

If you need a lightweight powered yacht tender for one or two people, start with the Navigator 250.

If you regularly carry a family or larger cruising crew, consider the Navigator 300.

If you want a compact boat that can handle fishing, exploring and general family use, look at the Discovery 280.

If you want the strongest balance of fishing space, portability and multipurpose use, consider the Discovery 330.

If onboard space and performance matter more than one-person handling, look at the Discovery 400.

If your priority is reaching remote fishing locations with the smallest practical packed setup, choose the Tactician 350.

Final Thoughts

The right inflatable boat size is determined by more than its length or stated passenger capacity.

Think about the complete experience:

Where will it be stored?
Who will carry and launch it?
Will it stay inflated?
How much equipment will be aboard?
How long will you spend on the water?
What motor will you use?
What will the boat be used for most often?

A slightly larger boat can transform a full day of fishing or exploring. A slightly smaller one can make regular launching, yacht storage and short tender trips much easier.

Choose the boat that best fits the way you will genuinely use it, rather than the unlikely occasion when you might need to carry the maximum possible number of people.

Compare every True Kit model by length, weight, packed dimensions, capacity and maximum outboard to find the best fit for your next adventure.
