Monachus Issa 45

Modern and elegant lobster-style boat

Monachus Issa 45

ISSA 45 modern and elegant lobster-style boat with smooth lines and a spacious outer cockpit. This boat is fast and strong when needed, but equally enjoys the benefits of its peaceful nature. It’s designed to the highest standards of the EC pleasure crafts category ‘A’.



‘Monachus-Issa 45’ is characterized by a strong construction. The hull geometry is designed without compromise, taking into account the best buoyancy. The longitudinal and transverse weight distribution are adjusted in the same way so that all the centers of gravity are set as low as possible. Structural water tanks were made between the central longitudinal ribs, which further strengthened the hull. In the event of damage to the most exposed underwater part, the contents of the tank will leak out and the boat can proceed to the service point. Superior stability is achieved by proper weight distribution and hydrodynamic tunnel design. In addition to contributing to stability, HD tunnels further strengthen the stern of the hull, reduce draft, and the propellers are better protected in case the boat passes over an unwanted floating object.
Due to the tuned bow buoyancy, the center of gravity around the CB point (center of the boat) and adequately balanced stern buoyancy, ‘Monachus’ has the effect of a balanced seesaw on the longitudinal wave. The result is a slight transition over the wave. The one-piece laminated and multi-axially curved windscreen gives the helmsman a fantastically clear view. An equally slightly raised bow at different cruising speeds ensures the lasting continuity of that clear view. Given the length of the waterline and the comfort of the ‘cruiser’ version for the ‘Monachus-Issa 45’, we underline the main features – unique, classically elegant, comfortable and safe!


Monachus Issa 45 is a versatile, practical, economical, and attractive boat. This boat provides comfort to all essential needs and activities during cruising. It is just as practical on day cruises as it is on longer cruises. One person can easily handle the boat on his own or with a little help, and its appearance will not leave the observers indifferent anywhere. Last but not least, Monachus Issa 45 is a boat with excellent navigability, safe in navigation, and smooth in every aspect.


Monachus Issa 45 is intended for the customer who wants a safe, functional boat of the appropriate size and wants to enjoy the cruising moments to the maximum. Monachus boat owners are mostly people of refined experience, so used Monachus is an extremely rare occurrence on the boat market even in the middle of the second decade of production.
