Forty knots at the top, and a 28 knot cruise that she holds without effort.
Twin Volvo Penta D6 diesel inboards are standard, with Volvo Penta IPS600 pod drives or twin Mercury Verado 400 outboards available for owners who prefer a different response at the helm. At 10 tonnes displacement, the KL 40 carries real weight for her length, and it shows in how she holds a line through a following sea rather than skating across it. A 1.2 metre draught keeps most marinas and anchorages within reach, and 1,300 litres of fuel give her a 300 nautical mile range, enough for a longer itinerary rather than a single long day out.
Clean lines, an open transom, and a deck built for a full day outside.
At 4.1 metres beam, the KL 40 carries enough width to make her deck spaces feel generous rather than tight, with room for twelve guests to move between bow, cockpit and swim platform without crowding each other. Teak decking and a wet bar set into the aft deck keep the social spaces working through the whole day, from breakfast at anchor to drinks after the last swim. The overall shape favours proportion over ornament: a straight sheer, an open transom for easy access to the water, and a profile that reads as capable rather than showy.
Two cabins and four berths, enough to turn a day boat into a real getaway.
A forward cabin takes the bow, with a second cabin set beneath the cockpit aft, giving the KL 40 genuine separation between the two sleeping areas rather than a single open berth. Between them sits a saloon built to change through the day: a lounge for the morning, a dining table by evening, and a full width double when the boat needs to sleep more than her two cabins allow. One crew member is enough to run her, which keeps the whole experience closer to owner driven boating than to a fully crewed yacht.
A galley built to be used, not admired from a distance.
Set within the main deck, the galley carries a refrigerator, a hob and genuine worktop space, enough to prepare a real meal rather than assemble a snack. It sits close to the saloon and the aft deck, so whoever is cooking stays part of the conversation rather than shut away below. Wide side decks and secure railings mean moving forward or aft while under way is straightforward even with twelve on board, and the whole layout is built around one idea: nobody on this boat should have to choose between being social and being comfortable.
The largest model in the Key Largo range, engineered in house from hull to helm.
At 13.5 metres LOA on a 4.1 metre beam, the KL 40 is designed, engineered and built by Key Largo’s own teams, which keeps her specification consistent with the smaller boats in the range while scaling up the comfort considerably. A new build starts at 650,000 euros. With a choice of diesel inboard or outboard propulsion, a 300 nautical mile range and berths for four, she suits an owner ready to move from day boating into something that can genuinely be lived aboard for a long weekend.
