1 Description

Ready-to-install Propulsion System – ARENS RVI SAIL 15

The ARENS RVI SAIL 15 is suitable for small runabouts and sailing boats. The engine, foundation and Saildrive

are designed as a complete system which, at 45 kg, is only half the weight of comparable systems and requires

40% less installation space. A real innovation is the plug-and-play principle, which allows the engine to be

removed quickly and easily when maintenance is required.

Powerhead – ARENS RVI 378-2Z

The heart of the system is a highly compact engine with designation "ARENS RVI 378-2Z". It delivers 11.04 kW

(15 PS) at 4,300 rpm and is the world's first inboard engine based on a two-stroke boxer engine with common

rail direct injection. The closed fuel system allows operation in unventilated engine compartments. Due to its

boxer construction, the ARENS RVI engine runs very smoothly and is low in vibration. Power is controlled via a

sensor on the throttle lever and no longer requires a throttle mechanism. With a maximum charge current of

58 A, the built-in generator delivers four times the charge current of outboard motors with the same power

output. The ARENS RVI SAIL 15 can compete with inboard diesel engines with its fuel consumption of only two

litres per hour at cruising speed.

Transmission and Foundation – ARENS RVI Saildrive

For the installation of the system, a supplied foundation is inserted into the hull of the boat, which is provided

with a mounting frame and serves to fasten the engine and Saildrive. The RVI power head and its leads can be

detached from the boat with just a few hand movements using quick-release couplings. At a weight of 35 kg,

lifting out does not require any lifting equipment. What's more, with its box dimensions of only 600 x 430 x 300

mm, the motor is extremely compact and easy to transport. This makes uncomplicated shipping in a crate

possible, which eliminates the need to transfer the entire boat to a service workshop for maintenance. The

expenditure for stationary wintering or maintenance is considerably lower compared to conventionally installed

diesel engines.

Advantages

The ARENS RVI Sail 15 is an alternative to outboards, as they are usually used on smaller sailing boats. With

this system, operational comfort and manoeuvrability can be significantly improved. Of course, its use is also

possible in other boat types where weight and installation space are limiting factors. Last but not least, the

ARENS RVI APP offers the possibility to inform yourself about the operating status of the engine via smartphone.

2.4 System Design

The ARENS RVI Sail consists of the powerhead (combustion engine) and the saildrive system, which includes a

powerhead pick-up device on the foundation, the foundation itself, a boot seal, and the underwater part. The

outer and inner wall of the foundation box shall be trimmed to the hull shape of the ship. The cut edges of the

foundation box must be permanently and watertightly connected to the hull by lamination!

2.6 Installation on hull

The walls of the fundament box will be cutted out according to the shape of the hull and stable connected by

lamination. The inner circular shaped wall is used for the implementation of the lower unit. This wall will be also

laminated to the hull, such that the connection is watertight.
