Low Emissions

Žaba’s systems were designed with environment in mind. Propulsion is provided by 2 x 15kW OceanVolt electric sail drives, 14kWh of LiFePO4 batteries, 1.2kW of solar panels. 

Modern Design

Hull shapes were designed by Grainger Designs. Žaba’s hull length to beam ratio is 13:1. The hulls are fitted with reversed wave piercing bows. Cockpit is covered with hard canopy supporting a full width main sheet traveler. Jib is self-tacking..

Space Craft Materials

Žaba was built using high tech materials. Most of the surfaces are from foam core tortured flat panels. The foam core sandwich hull panels came precut on a CNC router from ATL Composites in Australia. There are carbon reinforcements, some parts were infused.

History of Žaba

The history is a bit longer than one would want to remember. If boat building dreamers knew how long it takes to build a boat, multiply by four, no boats would ever be built. Žaba was built by Bukvaj Multihulls sro in Prague, on the Vltava river bank, close to the historic city center. Construction started in August 2011. The boat was test launched on 4th October 2017. 


Bespoke Manufacturing and Mobile Boat Repair

Since we built the whole boat, and several boats before Zaba, Bukvaj Multihulls sro (ex Bukvaj sro) plans to do mobile repairs wherever your boat or project is. Or actually wherever we can sail Žaba. We can do fibeglass work, fairing / painting, system upgrades, some electrical work. 



Don’t stop dreaming, or dream on!!

Žaba’s route so far

Most of the work was completed (ish) in Prague in April 2018. The boat first went down the river Moldau into Elbe, then up norht to Hamburg. The mast was stepped in Gluckstadt. In the summer of 2018 we sailed in the Baltic and up to Oslo through Copenhagen. Zaba spent the first winter in lovely Emden. And in 2019 Zaba took off through Duch canals, the mast up route to Amsterdam, Brighton, Brest, La Coruna, Lisabon, Algarve and through the Med to Greece.

In The Meantime

here’s how our frinds experienced the cat

The galley is good she should say. Ali sailed across the Bay of Biscay from Brest to Lisabon. What are you cooking Ali? Don’t know yet, something. It’s always delicious though.
