The Storm 23 is an elegant, semi-custom built daysailer that offers superb sailing performance and stunning looks, in a refined and easily managed package.

Like many of our range, she features our innovative water ballast system which keeps trailering weight to a minimum and gives great performance potential in light airs. Together with a carbon mast and modern fully battened mainsail she’s a joy to handle on and off the water.

A hull weight of approximately 500kg, coupled with around the same in water, plus crew brings her designed displacement to 1250kg. Twenty square metres of upwind dacron give her a sail area displacement ratio ranging from 16.9 (mid-cruiser) to 23.3 (more racer) depending on whether ballast tanks are full or empty. Similarly her well proven epoxy ply construction method gives an excellent length displacement ratio of between 6 and 7.2 making high speeds in moderate conditions very achievable.


Her coachroof is kept deliberately low to avoid spoiling the lines and is left open backed – the boat does not rely on any enclosed volume within it for large angle stability or buoyancy. A canvas cover pops on under the lip of the roof, and a washboard fits in between the seats to keep the worst of the weather out. Buoyancy is built in at either end under the floor, with extra provided under the cockpit seats. There is well over 2m of usable length in the cabin meaning over nighting is possible but we should be clear that this is not her primary purpose.

The rudder looks short to those used to modern profiles, but her double ended hull shape means it rarely lifts significantly and experience shows it will be more than ample.

A simple line raises it up on a long pintle for launching or sailing in shallow water. The centreboard is mainly housed under the self draining floor, so its length is extended without compromising ergonomics. She draws just 250mm with the board up (less if she is empty) but over 1.6m when down. This gives her blistering upwind performance and if well set up she will point as high as anything else afloat. The rig is a fairly normal bermudan comprising a carbon mast and boom, together with fat head mainsail and roller furling jib. The mast is keel stepped, in the sense that it rests on the self draining cockpit floor, with partners at cabin roof level to improve support and make single handed rigging easier. The mast has no spreaders which keeps the weight and windage down, but it does require a slightly heavier carbon cross section as a result. The fat head main has become a favourite, reducing the total mast length to only 8.2m – just 1.2m longer than the boat so fine for trailering.


The foot of the jib is kept deliberately short, meaning the tack is well aft of the stem head and the roller furler sunk into the anchor locker.  This means an asymmetric or code headsail could be flown from the stem head without needing an expensive or vulnerable bowsprit.

The outboard (petrol or electric) is designed to fit under the aft deck, which is slightly longer than would otherwise be needed. Her overall length makes this possible and it is an arrangement that we think will work well. The controls for the engine will protrude through the bulkhead and into the cockpit, and the lid lifts for refuelling or starting.  The cockpit drains into the outboard well which is faired off using our standard flap system that has proved itself on so many of our other designs. A separate fuel tank could be carried in the space just aft of the outboard.


The double ended hull form creates minimal resistance in light airs, but in heavy weather, with her long waterline, seaworthy hull and easily reefable rig, she gives a fast, safe and reassuring ride.

A powerful kicking strap means we are able to dispense with a mainsheet traveler, though that is still an option for those happy to forego cockpit space. The lines for trimming all sails lead back to the helmsman, the idea being that crew don’t have to get involved unless they want to.
