Marex 375 review

An amazingly practical, impressively roomy, storage-rich, feature-laden jack of all trades, the Marex 375 has few peers

The Marex 375 is the perfect boat for serial ditherers. People who just cannot make their mind up between a fast (37 knots) and sturdy offshore cruiser capable of intrepid voyaging, and a safe and sociable boat suitable for ferrying families at low speed along the inland waterways.

If you genuinely want to do it all, the new Marex 375 is one of the few boats that can. It achieves this by dint of its great deck design.

In good weather its deck spaces can be left almost completely open to the elements, but in the space of a couple of minutes its two sunroofs can be shut tight, its amazingly practical aft cockpit canopies swiftly battened down, and its cockpit doors closed off to produce a completely enclosed environment that nevertheless still provides an excellent and safe view out for the skipper and the crew.

Two other things stand out. For a 39ft (12m) boat, the scale of everything is impressive.

Headroom is generous throughout, and only national league basketball players are going to grumble about a mid cabin berth that measures 6ft 7in x 5ft 10in (2.01m x 1.78m).

The 375 is also bursting with stowage, for example four lockers, one wardrobe, five drawers and four usefully fiddled shelf spaces in that roomy mid cabin.

Deck stowage is good too, and it is an easy and very safe boat to move around, thanks to sturdy handrails and deep toerails.


Few boats offer such a large and diverse range of engines. The 375 can be ordered with shaft drive or sterndrive, a single or twins, diesel or petrol engines, and with total power ranging from 400hp to 600hp – all told nine different options.

Plenty of power and agility thanks to 600hp and twin sterndrives

Our test boat had the most powerful twin Volvo diesel D4-300hp DPH sterndrives, which powered our (slightly under-revving) 375 to 36.7 knots.

If you’re happy with around 4 knots less, then either the big single D6-400hp sterndrive or the twin D3-220hp sterndrive will dish up less noise and vibration, and doubtless better fuel consumption too.

The 375 is all about single-level living

If you’re happy travelling a little slower still, or have slow speed inland waterways in mind, the single 435hp shaft drive is the one to go for.

Although the Marex 375 trades its sibling’s aft cabin for a roomy cockpit, it remains an amazing jack of all trades. Few offer such elevated levels of practicality, and its genius canopies alone are reason enough to buy the 375
