Houseboat engines

vantage

drawback

construction

compact construction

attachment

easy assembly/apart from a tank and steering cables, no fixed installation required

HP

Are there from two to over 300 hp, smaller engines up to 5 hp do not need a tank as their own tank is available

prize

20 percent more expensive than inboard engines, higher purchase and maintenance costs for two engines

draught

Engine draft, propeller must flow correctly and lie below the bottom of the boat, the engine anti-cavitation plate must be placed two centimeters below the keel

Shaft length

Long shaft/ ultra shaft lengths are available for purchase max. 63cm

Assembly problem with larger houseboats due to the short shaft length max. 50 cm

propellers

Push or work propeller must be purchased separately and provide a remedy to increase thrust

Standard propeller is designed for fast boats, is too small (power is only insufficiently converted into thrust)

manoeuvrability

good maneuverability when using two motors

internal combustion engine

only available as gasoline engines

vantage

drawback

construction

classic motorboat ship drive, consists of a motor mounted in the hull, turning gear, outwardly guided shaft with propeller, construction is suitable for monohulls

Only suitable for catamarans if you install two drive units (higher costs)

attachment

The motor is mounted far ahead, due to which individual reaction to weight and trim problems is possible via the appropriate installation position

HP

20 hp to several 1,000 hp

prize

inexpensive, reliable, efficient

draught

The engine and propeller are at the bottom of the ship

manoeuvrability

What is required is a separate steering system (hydraulically, electrically, mechanically) connected to the driver's cab, better maneuverability with additional assistance from bow and stern thrusters

limited maneuverability, as rudder only flows when the speed is sufficient (difficult approach and departure manoeuvres, especially when there is wind)

internal combustion engine

Diesel, - gasoline (combination with electric motor possible, reverse gear not required) - hybrid drive

The bow and stern thrusters are powered electrically or hydraulically; sufficient power supply is required

vantage

drawback

construction

greater flexibility in room layout, multiple drives possible on one generator, individual layout of the installation space

attachment

The generator can be in the center of gravity

HP

powerful on-board power supply from the same unit, stronger thrust across the entire speed range, efficient motor (efficiency 96%)

Shaft length

several control stations possible

manoeuvrability

full rowing effect even at the slowest speed, extremely improved maneuvering characteristics

internal combustion engine

very quiet/silent driving/environmentally friendly, plenty of electricity on board, extremely low travel costs, performance-adapted operation using AGT technology

vantage

drawback

construction

Engine sits in the hull, propellers sit on an L-shaped shaft under the boat floor

attachment

steerable saildrivers do not require an extra rudder blade, good handling, comparable to outboard motors

Fixed saildrivers need an additional rudder blade

HP

11 HP — 180 HP

prize

€8,000 — €60,000

draught

Is permanently installed, cannot be lifted hydraulically, increases draft by half a meter

manoeuvrability

comparable to outboard motors

internal combustion engine

designed for small diesel engines

vantage

drawback

construction

Outboard and inboard engine combination

Engine is in the hull of the boat, transmission and propeller outside, unsuitable for practice

HP

130 HP — 700 HP

Designed for fast boats, therefore not really suitable for houseboats

internal combustion engine

Gasoline and diesel engines
