Knowing where you’re going: this is the idea you get when speaking to the creator of the L30, Rodion Luka, Ukrai-nian silver medallist in the 49ers at the Athens Olympics, and to Andrej Justin, the designer famous for having transformed the ideas of Russell Coutts into a successful one design, the RC44.

miles a speed of 4.5 kn but we did more than 7 kn going back in-to port against a stiff wind. The boat is also trailerable, thanks to the retracting keel (useful also on short summer cruises for lan-ding on the beach) and the mast that rests on the deck on a spe-cially designed rest, and is easy to haul just using the halyard. The L30 has no particular innovations in its construction, but of-fers the performance of a pure racer with comfortable space be-low decks. The water lines are very modern and the result of very refined work, but the most original aspect is the way they are of-fering to the market a boat conceived and carefully studied for a very specific range of uses: corporate events, sailing schools and short family cruises.
The business plan and use for corporate eventsRodion Luka is not looking to sell individual boats (though he would be quite happy to do so) but to find yacht clubs, sailing schools and promoters interested in buying a fleet of at least six
boats with a business plan that aims for breakeven in four years at most, using the boats for corporate events and club races. Lu-ka knows what he is talking about: he manages a fleet of Platu 25s available to members of the Kiev Yacht Club who book them even for short outings, like booking a court at a tennis club. It must be underlined that these boats were continually for corporate events, company racing or teambuilding. However, a top manager or an important client, perhaps a woman, could feel uneasy on an overly spartan racing yacht and not make the most of the opportunity of-fered. This is the reason for the choices below decks, especially as regards the head which is particularly large for the size of the boat, little more than 9 m. With the same target in mind is the choice of the twin wheel helm, apparently an unnecessary weight and extra cost, a tiller would be perfectly all right on a 30 footer and is more immediate, but for a beginner helming with the wheel is more intui-tive. The same goes for the bowsprit which is retractable and not fi-xed to avoid risks in case of collisions. The final cost is still to be de-

fined, but they are trying to keep it within €70,000, plus the sails (there is a full set by UK Sails in carbon offered at a special pri-ce of just over €8000) and the Oceanvolt electric motor at €4500 in the 4 kW version, €8000 for the 6 kW model. With at least 40 days of usage over the year, the business plan expects breakeven within four years. However, the days of usage are an underestima-te, especially in the Mediterranean or in areas where a lot of sailing is done the effective number of days of usage could well increase considerably. Already on order are eight models that will join the Platu 25s of the Kiev Yacht Club, a fleet will probably be shipped in Japan and at the same time Rodion Luka is working on his many contacts to create fleets in the Mediterranean, Baltic, Arab Emira-tes and the USA. If the development project goes on even partial-ly in the direction it has taken, it is probable that at least a couple of other yards will be involved in production, both to meet demand and to optimise delivery, the cost of which needs to be considered.

The waterlines When you are deciding which designer to call in for a new boat, one of the elements you consider is whether he has already de-signed similar boats. In the case of Andrej Justin there was not on-ly the design of the most competitive one design of the moment, the RC44 designed with and not for Russell Coutts, which makes a big difference in terms of constant involvement in every small-est detail. There are other one designs of around 10 m by An-drej: from the Justin Ten of the past to the recent Code 8, TOD 33 and Nautic 37. From the evolution of the waterlines of these boats, together with many other components and variables, come the waterlines of the L30, with a flat bottom without excesses and a marked chine, since the maximum beam was limited by the di-mensions needed to fit the boat on a trailer.
Tests on the water Nautech had the chance to try out the L30 in the Bay of Pirano in Slovenia on a day when the Bora wind was gusting up to 35 kn. Manoeuvres when leaving and entering the port showed the ef-ficiency and reliability of the electric motor, whose power is ve-ry smoothly controlled by a nicely designed accelerator placed on the side, like the classic throttle lever. To increase range during cruises, the motor can be used as a hydro generator, so under sail with the folding propeller blades open the batteries can be re-charged. A 30 footer in the conditions we sailed in is close to its li-mits and demands an expert crew. And that’s what we had on bo-ard, starting from Rodion Luka at the helm: apart from his Olym-pic medal, he also helmed for the Russian team in a recent edi-tion of the Volvo Ocean Race. We got an idea of his ability reaching as much as 24.5 kn, with a peak of 24.7, literally flying on a bro-ad reach. But much more important than the pure speed was the stability the boat showed, never broaching although it carried too much sail for such a strong wind. Certainly the credit goes to Lu-ka at the helm, but also to the general balance and the twin-ra-ther helm. Despite the high seas and the almost insane speed for a 30 footer, the boat was very dry thanks to its modern trim with the bow raised, the high sides and generous deck house. Close hauled with steep waves and the jib too big for the wind strength, the L30 had some trouble pointing high, and we preferred to go for VMG a little further off the wind but faster but, once in shelte-red water with no waves and less wind the boat pointed very high. It must be underlined that the boat was still in the final test phase and was intentionally taken beyond its limits to show up any pro-blems, to define the best setup and to decide on any last modifi-cations. We are sure that in more common conditions with light air and calmer water it will behave excellently on all points of sailing, and probably a smaller jib will be provided to sail safely and well even in strong winds. Finally, the IRC rating is expected to be quite favourable considering the sail area is not excessive (though there will also be a Code 0 for sailing between around 60° to 110° Ap-parent Wind Direction), the displacement is not that light and the beam relatively narrow. This will allow the L30 to take part in fle-et races without being penalised too much, further extending its possible uses. © ALL RIGHTS RESERVED
