Steam Outboard Motor Competition 2015

25 Feb 2015 19:02 | Deleted user

The steam powered outboard motor competition will be returning again after the success of 2014’s competition (see here and here for what people got up to last year).

 

Entry is free to any SBA members, who can take part either individually or in small teams. If you are interested in taking part in the competition but are not an SBA member why not join the Steam Boat Association?

 

Form of the Competition


The SBA will provide a boat to which the competitors attach a steam outboard motor.  The boat will include a boiler (with a fireman) to provide steam for the engine.  The entrant will then race against other entries in a time trial.


Definition of a Steam Outboard


For the purposes of this competition any device which will mount on the transom bracket of the host boat and receives steam from the host boat fits the definition of an outboard motor.  

A steam control valve is required on the engine for the entrant to control the engine.

There is no requirement for the use of a traditional outboard motor leg or even to use a propeller. Similarly the engine does not have to be of the conventional steam engine arrangement.  Be as creative as you like!

The outboard motor does not have to include a steering system as this will be provided on the host boat (although it may if you wish).


The Host Boat


This year the host boat will be specially assembled for the competition (she will be a similar size to last year’s host boat - Mark Rudall’s Chimera II.) She will have a water tube boiler producing saturated steam at 100psi. 

Steam will be supplied to the engine via an insulated flexible hose which will be fitted with a 3/8” BSP male fitting.

 







Form of the Competition


The competition will be in two parts; a time trial and the judges’ selection for technical excellence.

1 - Time trials

The time trial will involve timed runs around a course, the fastest of the runs will count.

The fireman of the host boat will attempt to maintain a boiler pressure of 100psi (likely to be lower at the engine).  The entrants are responsible for control of steam supply to the engine and for steering the boat around the course.

2 - Technical excellence

The judges will decide on their favourite entry, based on innovative features, quality of workmanship, presentation etc.  The judges’ decisions are final.

 

Location of the Competition


The competition will take place in the course of the Beale Park Boat Show which is on the 5th-7th June 2015.  Entrants will be able to have several runs throughout the duration of the show.




Safety & Environmental Considerations


Entrants are responsible for their own safety when operating their plant.  It is suggested that you complete a simple risk assessment to identify risks of your design and take the necessary steps to mitigate against them.

The outboard motor must not pollute the environment and measures to prevent oil escaping from the outboard motor MUST be taken.  Minimal cylinder lubrication may be necessary but care should be taken that excess oil droplets do not find their way into the lake. The judges will need to be satisfied that your engine will not pollute the lake before allowing the engine on the water.

The judges and the fireman of the host boat reserve the right to stop the competition at any point for reasons of safety, to prevent damage to the host boat or other craft or to prevent pollution.
