Product Description

SpearFish range

SpearFish Boats are relatively long and narrow roll-up inflatables. Their unique shape makes them very easily-driven, which means you can achieve decent speeds with relatively small (lightweight and inexpensive) outboard motors. And because the deflated boats fit in a bag (that fits in most car boots), you won’t need a trailer or mooring.

This all makes for a highly portable, and refreshingly affordable, means to get afloat.

For example, with a 6hp motor the smallest 450 (15ft) model will do 14-15 knots with two adults on board, when a typical-shape inflatable dinghy would be languishing in single figures. The ride is also remarkably comfortable – she slices through the tops of waves, rather than bouncing over them. And the stability is also very good, because as soon as she heels a few degrees.there is an immense amount of “push back” from those long (4.5m long) side tubes.

As David Parker, in PRACTICAL BOAT OWNER Magazine (August 2016) summarised: “It is certainly both very quick, and a lot of fun.”

Why the emphasis on smaller outboards? Well, smaller engines are cheaper to buy, cheaper to run (fuel/servicing costs) and, perhaps the number one factor, lighter. As one customer put it:

 “If you need a portable boat, you need a portable engine too“.

Outboard motors up to 6hp are a comfortable one-person lift (13-27kg); 8 & 10hp motors are just about manageable (lightest is 37kg). We’ll say it again: the SpearFish 15 will reach speeds of 12-15 knots with two adults on board, on just 6hp. Very few other boats can do that, let alone roll-up inflatables (we can’t think of any). And of course it’s even faster if you’re boating solo.

The 450/15ft model will take up to three adults (or two and two children), but if you are going to go out frequently with more than two adults then you may wish to consider the 550/18ft. It’s a metre longer, 20cm wider (which actually gives it nearly double the volume), and able to take motors up to 10hp. The 550 still goes very well with 6hp, but if you can cope with the weight something like the Tohatsu 9.8 (37kg) is much quieter and smoother (two cylinders rather than one).

SpearFish 450 family fun

Alongside decent carrying capacity, low power planing, and portability, we also wanted a boat that had reasonable ability in waves. Even if you’re a committed “fair weather sailor” it’s always possible to get caught out in conditions rougher than you intended, if wind or tide change for example. So we’ve built in a V-shaped hull underwater at the bow. This is made by forcing the high-pressure drop-stitch floor into the desired shape, which also has the desirable side effect of making the hull very stiff. (Flat-bottomed boats are fine on completely flat water, but not fine if you’re heading into waves.)

And if you’re going to be able to go out in waves, deliberately or not, it might get “splashy”, so we also wanted a sheltered area at the bow. We didn’t want that to involve fiddling about with a frame, with small bits to lose, so it’s a fully-integrated canopy with inflatable tube supports. As it turned out the V-floor and high bow tubes of the SpearFish makes her a very “dry” boat anyway, but we retained the canopy idea as it helps with aerodynamics and provides some shelter from the wind. (Also it seems, a place that young children like to play in – and if they’re happy you will be!)

WHAT ONE OF OUR CUSTOMERS SAID about his SpearFish: SpearFish testimonial (1Mb PDF)


Here we can see the folded SpearFish fitting comfortably in the boot of a VW Golf hatchback – with the rear seats still up. A small outboard (in this case a Tohatsu 3.5hp) will also fit on top. This then is a complete boating package for all the family, that fits in a family hatchback, with room for the family too. 


SpearFish 550 18ft OH
Spearfish Inflatable Motor Canoe, 15ft


SpearFish 450/15, boat only, £1,495

Standard specification includes: tubes made from German-made Valmex multi-layer fabric; high pressure drop-stitch lower hull with V-shape at bow; integral inflatable bow canopy; stirrup inflation pump; pair of oars/rowlocks; lifelines all round; strong towing/mooring eye and lifting handles; outboard bracket.

SpearFish 450/15 with Suzuki 6. Engine weight 23kg. We think this is the best engine combination for the SpearFish if you want to go distances on the sea, fast with one on board, not much slower with two, and very adequate for three. Package Price £2550

SpearFish 450/15 with Epropulsion Spirit 1.0. Engine weight 18kg. The electric option, reaches speeds up to 5.5 knots (more than most river/harbour limits) and at 4 knots should have a range of at least 10 nautical miles (probably 12 or even 15nm, depending on conditions/load). Beautifully smooth/easy to use. Package Price £2895

SpearFish 550/18 boat only. Standard specification as 450 (ie includes bow canopy, oars, seats, repair kit, storage bags, manual pump, etc) £1950

SpearFish 550/18 with Suzuki 6. A nice balance between engine weight and speed, about the same figures as the 450 but will start to get bogged down with more than three adults on board. Package Price £2995

SpearFish 550/18 with Tohatsu 9.8. Our favourite as long as the engine weight (37kg) is manageable for you. Even if 6hp is sufficient, a 9.8 twin cylinder making 6hp will be vastly more quiet and smooth. Package Price £3695

SpearFish 550/18 with Epropulsion Spirit. As with the 450, a 1kW electric motor is plenty powerful enough to get up to (legal) harbour/river speed limits, and so nice to use. We have several customers very happy with this combination. Package Price £3350

Options include:
– Transport Cart. Effectively a big kayak/canoe trolley that fits underneath the boat. We were looking at transom wheels, but this is actually better, because you can put the wheels part way along the boat making it counterbalanced and very easy to move along. £99

SpearFish cushions & bag

– 12V Electric Pumps. Not massively quicker than manual pumping, but definitely easier… We recommend either the piston-operated Bravo BP12 at £95, or the two-stage, quicker (compressor for volume, then piston for pressure) Bravo BTP12 at £125. (NB Both pumps are self-regulating, ie you set the pressure on a dial, and it switches off when it gets there.)
– Cushions/underseat bag set. Three cushions for the top of the seats, plus one bag that suspends underneath one of them. The bag is removable so you can take it with you to the pub or whatever! £75 for the set

Nestaway Spearfish 15 with Suzuki 5hp

In the picture below, on the left is a fairly well known “conventional shape” inflatable dinghy (a 3.2m, 11ft version), often described as a “performance sports boat”. On the right is a SpearFish 450 (15ft). Assuming the same engine power and load, you can probably guess which one is easier-driven and faster; slams less when it hits waves; and gives a smoother (and drier) ride…

Hull shape comparison

BELOW: Perfect for a spot of fishing… and plenty of stability to stand up and cast.

The “official” capacity rating is 3 adults, or 2 and 2 children. But if the children are small, and if like here it’s a river trip on a calm day… more is probably fine! The maximum weight capacity – people, engine, stuff – is 450kg and even that’s quite conservative.

SpearFish, with her low drag hull, is almost certainly one of the best inflatable rowing boats ever built. Shown here with a single paddler, the balance is even better with a tilted outboard – or a second person – at the stern.

SF450R rowing

As several divers have observed, SpearFish would make a fine support vessel and – particularly if you have a red one – doubles up as an unmissable surface marker.
