i The Displacement Length Ratio (DLR) is a figure that points out the boat's weight compared to its waterline length. The DLR is obtained by dividing the boat's displacement in tons by the cube of one one-hundredth of the waterline length (in feet).
The DLR can be used to compare the relative mass of different sailboats no matter what their length:
The Seawind 1190 is a 39’ (11.9m) fast cruising catamaran designed by Richard Ward (Australia). She is built since 2017 by Seawind Catamarans (Australia).
Upwind: under 18 the ratio indicates a cruise oriented sailboat with limited performances especially in light wind, while over 25 it indicates a fast sailboat. [links]
The Seawind 1190 is as well listed, on Boat-Specs.com, in Sport version (see all the versions compared).

The 1190 Sport has three cabins plus a toilet in each hull. Our review model came with two double cabins forward in each hull plus a smaller one on the starboard aft quarter. The owner has most privacy in the port hull with double bed forward which lies athwartships while the navigation station adjoins this and the bathroom is aft. The elevated bed means limited headroom but it also gives good storage space beneath and in the forward bulkhead, while natural light comes from two opening skylights and rectangular portlights. In the corridor the navigation desk has a swing-out stool and locker. The desk is a spacious charting area with shelf above and bulkhead space for electronics – in addition to the instrument and power switches already there. Unlike European boats that must comply to CE standards, there’s no escape hatches, but these could be a custom addition I feel; especially on a race boat that pushes its limits. Elsewhere, cabin doors are honeycombed composite yet felt strong without any flimsiness. The aft section of the port hull is taken up by the bathroom which has an electric head and separate shower cubicle – with easy clean mouldings throughout. Behind it, a door leads to the empty engine bay, as the outboards are inside bridgedeck wells. The removal of the diesel engines frees up a lot of storage space and as I noted while looking from the pontoon, lowers the waterline by several inches. here
Looking at the aesthetics, as I made my way down the pontoon at Multihull Central’s marina at Rozelle, showed the 1190 Sports topside profile to be a wee bit smoother than other models; showing how the moulds were effectively tweaked for this boat. There’s a stylish and sturdier carbon/GRP laminated black targa to hold Seawind’s traditional mainsheet track. This targa closely adjoins the full length GRP bimini to weatherproof the aft cockpit. Elsewhere in the aft cockpit there’s twin helms, which are my preference for close-quarter handling and racing catamarans. At the main port binnacle there’s B&G instrumentation and autopilot, including the swing-out plotter from the removable saloon window, plus throttles for the twin outboard engines. The starboard binnacle included a single B&G readout with compass; so all good. Stylish touches are the composite steering wheels which give the steerer a chunky grip (compared with Seawind’s traditional metal ones). Storage for the removable saloon windows in slots is a useful yet simple improvement on this model. more
The result is a stretched and performance version of the popular 1160 Lite – that was created by shedding internal weight and heavy diesel engines; saving 750kg. For cruisers the advantage of increased waterline usually translates to better daily mileages while the daggerboards greatly improve stability and upwind performance (compared with mini keels used on all other Seawinds). For adventurous sailors it can also mean beaching in top spots like Lizard Island in Queensland – a Mecca for Top End voyagers awaiting prevailing winds to whisk them around northern Australia. This redesign was not taken lightly by the company, so experienced Australian performance catamaran builder Alan Carwardine was asked to collaborate, along with French naval architect Francois Perus (who worked with Corsair trimarans). Having raced several of Carwardine’s boats, including the Stealth model in the last Multihull Championships in Phuket, I’ve been duly impressed with his designs.
Installing a daggerboard housing into the GRP resin-infused hulls does use some internal space, such as blocking one external window in the galley, but it’s a reasonable price to pay for better performance. Even better is how Seawind’s design team has incorporated the daggers into the high topsides without any protrusions. Other performance features of this new 1190 Sport include replacing the alloy main crossbeam with a stiffer carbon spar – using the lightweight construction expertise from sister company Corsair. The sail wardrobe is also beefed up in the Sport with a carbon bow sprit added to fly big headsails and a 15% larger mainsail; made of aramid carbon cruise laminate by Doyle Sails. A taller alloy mast has been used and to reduce weight aloft dyneema standing rigging incorporated.
The longitudinal galley dominates the mid section of the starboard hull and one window is blocked by the otherwise largely inconspicuous dagger casing. Utilities included Seawind’s signature double drawer fridge freezer that swings open beneath the composite worktops; and there’s locker space above as well. Outboard on each side of the daggerboards casing sits the twin sinks and three burner stove – with an option for an oven beneath. Having used this layout at sea and at anchor, I find it works well as it has enough room for two to cook while supporting you in a swell. Ventilation is good with a very large opening portlight and the open space above your head also gives airflow from the saloon. Elsewhere in the starboard hull is the double berth forward, located fore and aft. Again it has an opening skylight and of course hull portlights. Walking aft, through the galley takes me to the stern three-quarter bunk which is a pleasant spot, especially since the hot engines beneath have been removed. The large portlights, bench and cavernous storage locker underneath all go to make this a comfy single (or double at a push) berth. here
