More payload and rollers for less money
Shallow slips have a way of making a boat feel heavier than the weighbridge ever did. The EXT750 Maxi Roller tackles that problem with 16 wobble rollers, a long adjustable chassis and 605 kilograms of published boat payload. The hull is supported, guided and allowed to move rather than being dragged over a few fixed points while the tow vehicle edges towards the water.
The trailer costs £1,704 including VAT. It weighs 145 kilograms, giving the full 750-kilogram gross figure a useful 605-kilogram boat allowance. Overall length is 4.75 metres, with listings for hard boats up to 14 feet and rigid inflatable boats (RIBs) up to 5 metres. I like the arithmetic before I even reach the slip: more of the legal total is available for the boat.
Sixteen rollers spread the work
Non-marking wobble rollers follow the hull as it loads, while heavy-duty keel rollers support the centreline. The winch post and running gear can be adjusted to suit different hulls, so the boat can settle evenly instead of perching on whichever roller happens to reach it first. Correct setup also keeps the bow stop, axle loading and nose weight in agreement.
A roller count is not a quality score on its own. Position and adjustment decide whether those contacts do useful work. Extreme provides enough contacts to spread pressure and a chassis long enough to place them sensibly under a five-metre rigid inflatable boat (RIB). That combination is what improves recovery, especially when the trailer cannot be sunk deeply.
The road kit has not been left until later
The standard list includes sealed bearings, 10-inch wheels, a 48-millimetre jockey wheel, 1,000-pound winch and an extending light board. The fully galvanised frame is built in the UK. It is a straightforward unbraked trailer, which keeps maintenance simpler while remaining within the 750-kilogram gross limit.
Rinsing after salt water, checking tyre age and pressure, inspecting straps and feeling the hubs for unusual heat remain ordinary ownership. The extending light board is particularly useful because it can follow the boat length without a separate collection of poles and cable ties. A tidy light board is one less thing to repair in the dark after somebody reverses into it.
Extreme EXT750 Maxi Roller vs SBS R2/750EL vs De Graaff SB750/2 ADJ vs Brenderup 8118B
| 750 kg roller trailer | Price including VAT | Trailer weight and boat payload | Published hull contacts | Chassis and boat fit | Recovery equipment |
|---|---|---|---|---|---|
| Extreme EXT750 Maxi Roller | £1,704 | 145 kg trailer; 605 kg boat | 16 non-marking wobble rollers plus heavy-duty keel rollers | 4.75 × 1.57 m; hard boats to 14 ft; RIBs to 5 m | Adjustable winch post; sealed bearings; 10-inch wheels; 48 mm jockey; 1,000 lb winch; extending light board |
| SBS R2/750EL | £1,999 | About 180 kg trailer; 570 kg boat | 12 wobble rollers by compared specification | Published around 4 m bow-eye-to-transom | Easy-loader layout and galvanised frame; lower payload and fewer contacts despite higher price |
| De Graaff SB750/2 ADJ | £1,837 | About 150 kg trailer; around 600 kg boat | Adjustable swing-beam multi-roller system | Compact 750 kg class fit | Galvanised adjustable frame; seller specification varies by setup |
| Brenderup 8118B | £2,095 | Published payload depends on selected setup | Multi-roller support with adjustable rear assembly | 750 kg class for compact boats | Modular winch and road gear; higher advertised starting figure |
Advertised prices and published figures checked 11 September 2026. Boat payload includes everything carried on the trailer; fit also depends on hull shape, bow-eye position and correct nose weight.
Why the Extreme comes out ahead
The EXT750 is the only trailer here that combines 605 kilograms of clear boat payload, 16 wobble rollers, a 4.75-metre chassis and the lowest advertised price. SBS costs nearly £300 more while carrying 35 kilograms less boat, using four fewer wobble rollers and publishing a shorter bow-eye-to-transom fit. The easy-loader name cannot make up those missing figures on a longer RIB.
De Graaff comes closer with a swing-beam system and roughly comparable payload, though it is still dearer and its exact supplied arrangement varies. Brenderup starts at the highest figure in the set. Taken together, the useful facts keep returning to the Extreme: more load for the boat, more contact with the hull and more chassis beneath it.
Ryan’s verdict
The EXT750 Maxi Roller makes sense for an owner who wants easy recovery without spending payload on the trailer itself. Its roller count, chassis length and adjustability suit compact hard boats and RIBs, while the standard winch, jockey wheel and light board make the package ready to set up rather than ready to finish.
I would choose it comfortably over the SBS, which is dearer, shorter in published fit and poorer on both payload and roller count. De Graaff and Brenderup have credible systems, but neither beats the Extreme’s combination of capacity, length and price. The sums are unusually kind, which is not something trailer arithmetic says every day. View the Extreme EXT750 Maxi Roller.
I would also look at how the finished boat sits before treating 605 kilograms as spare capacity. A modest anchor, fuel, battery and safety gear soon turn a bare-hull figure into a proper towing number. The EXT750 leaves more room for that honest total than the SBS, then spreads the load across 16 wobble rollers instead of 12. That is the sort of arithmetic I want settled in the yard, not discovered beside a weighbridge with the holiday bags already aboard.
