Bow Installation Considerations and Precautions

EN

• The thruster must NOT be installed in compartments that require ignition proof electric equipment. If necessary, make a separate compartment. (NB: Ignition Protected systems are tested to be installed in areas with possible explosive gases in accordance with ISO 8846)

• The electromotor will generate some carbon dust so any storage compartments must be separated from the thruster to prevent nearby items becoming dusty/ dirty. (NB: IP version motors generate dust but are enclosed.)

• When installing the thruster electromotor in small compartments, ensure the compartment is well ventilated to allow for cooling of the electromotor.

• If the height of the room you are installing the thruster is limited, the thruster can be installed horizontally or at any angle in-between.

- If the electromotor is positioned more than 30º oﬀ vertical, it must be supported separately.

- Beware of keeping installation within advised measurements. No part of the propeller or gear house must be outside the tunnel.

• Do not install the thruster in a position where you need to cut a stiﬀ ener/ stringer/ support that may jeopardise the hull integrity without checking with

the boat builder this can be done safely.

• The electromotor, components and cables must be mounted so they remain dry at all times.

• We advise painting the gear house and propellers with antifouling. (NB: Do not paint the anodes, sealings, rubber ﬁ ttings or propeller shafts)

• Do not  nish the inside of the tunnel with a layer of gelcoat/ topcoat or similar. There is only room for a thin coat of primer and two layers of anti-fouling

between the tunnel and the props.

• Don’t install the electromotor close to easily  ammable objects or equipment as it will reach over 100°C before the temperature switch is activated.

• Do not store items close to the thruster motor. Any loose items near the thruster motor cis a potential  re hazard and can cause undesired short-

circuiting.

Aim to install the thruster as far forward as possible (1)

Due to the leverage eﬀ ect around the boats’ pivot point. The distance diﬀ erence from the boat pivots’ point to the thruster will determine the amount of

real rotation power for the boat.

Aim to install the thruster as deep as possible under the waterline (2)

Deeper installations prevent air from being sucked into the tunnel from the surface, resulting in reduced thrust performance and increase noise levels

during operation. Deeper installations increase water pressure for maximum eﬃ ciency from the thruster.

The centre of the tunnel should be a minimum of 1 x the tunnel diameter below the waterline. The installer must make evaluations based on thruster performance, boat type and operating conditions. As a general recommendation, the position of the tunnel should not be a minimum of 1/4 of the diameter of the tunnel from the boat keel. (NB: This can be overlooked depending on the installation methods deﬁ ned in this manual.)

Optimal tunnel length

Achieving the correct tunnel length depends on many factors from the hull type, operation and environmental conditions. Tunnels should avoid being longer than 4 x the tunnel diameter as this will reduce thruster performance. (NB: Installing long length tunnels can ﬂ ex/

bend over time and may require additional support. Consult with a naval architect.)

1. Do not allow the variable length of the tunnel walls to vary in length excessively. EG. the top tunnel wall is x 4 longer than the bottom wall.

2. If the tunnel is too long, the friction inside will reduce the water speed and thereby the thrust.

3. If the tunnel is too short (typically only in the bottom section of the tunnel) cavitation problems can occur as water  ow will not be able to

“straighten” itself before reaching the propeller. This cavitation will reduce performance and increase noise during operation.

Increase tunnel length to prevent a circular water vacuum cavity between the propeller and the hull of the boat.

Tunnel Length

Water Forces

Increase tunnel length to protect the propeller from water forces when high-speed cruising.

MC_0003

Thruster within the tunnel

It is important the propellers and the lower unit/ gear leg must be entirely inside the thruster tunnel. Propellers that protrude from the tunnel will not perform as intended.

4. Standard Use Tunnel length must be long enough to ensure the propellers are not extruding the tunnel.

5. Flat Bottom Hull Tunnel lengths must be longer than the standard measurement outlined within the manual to ensure a circular vacuum is not created between the thruster and the bottom of the boat.

6. High-Speed Boats Tunnel lengths must be increased to protect the propeller from damage when crashing against the water surface during high-speed cruising. (NB:

This can include the length of a spoiler)

Water Deﬂ ection

EN

MC_0003

1. A possible problem in sailboats or fast powerboats is that a non-rounded surface can generate drag from the back face of the tunnel, as it creates a

“ at” area facing the  ow of water (1).

This problem can be solved in two diﬀ erent ways, depending on what is possible or easier to perform.

2. The best solution which generally reduces the most drag is to make a recess in the hull at the back of the tunnel. As the back face is removed

water can  ow freely past the tunnel entry. The depth and shape of this recess will depend on the boat and the angle facing up/ down aft of the tunnel insert. Normally it is angled slightly down because of the water  ow on this area (2).

3. Making a de ector/ spoiler in front and underneath the tunnel can also reduce damage to the thruster and drag. The de ector/ spoiler will push the water  ow out from the hull so water can pass by the back face of the tunnel. The shape and size of this de ector/ spoiler will depend on the hull shape. The easiest way of making the de ector/ spoiler is to retain a part of the lower forward area of the tunnel while installing the tube. Use this

area as support to mould a soft curve/spoiler shape from the hull. (3).

4. The thruster propeller can spin (passively) producing noise while sailing or cruising as water is forced through the tunnel. Water ow directed

through the tunnel at high speeds, during turning or as the boat bumps waves while underway can also damage the thruster (4).

(NB: As a rule, you should not see the back face of the tunnel when standing directly in front of the boat looking aft.)

Pos. B

EN

Some sailboats have a  at bottom and shallow draft in the bow section. This can make installing the thruster as far forward from the boats main pivot point diﬃ cult. (Fig. 1).

However, it is possible to install a tunnel thruster in most sailboats, even when the hull does not directly support the  tting of a tunnel.

Instead  t the tunnel halfway into the underneath section of the existing hull. Strengthen it with a de ector/ spoiler directing the water  ow around the

tunnel. This will allow installation of the thruster in the proper position on the boat, maintaining the reliability and space advantages of the tunnel thruster.

This installation is being used by some of the world’s largest sailboat builders and has proven to give little to no speed loss during normal cruising. This

can also be an installation method for  at bottomed barges to avoid extremely long tunnels and large oval tunnel openings in the hull.
