Bob’s Steam Trawler
The following pictures are of a steam trawler that Bob is building.
It is the St Nectan from Mountfleet Models and is 69 inches long with a displacement of around 55 pounds.
The steam plant is a self-designed and built centre flue boiler with ceramic gas burner. There are two water feed pumps, these are the Stuart hand pump for initial priming and a Stuart steam powered pump with automatic control for normal topping up during sailing.
The boiler is fitted with automatic pressure control of the gas supply to the burner. Gas supply is from custom built tanks that are removable from the boat though they can be refilled whilst installed.
Fresh water for the boiler is carried in a tank near the bow of the boat and the volume of gas and water should provide around 2 hours of non-stop steaming.
The engine is the Stuart compound launch engine built from castings by Bob. The boat and its machinery have been on the slipway since 2001 but as of January 2016 are nearly complete. The engine has been run in on compressed air as has the steam pump.
Radio control of the rudder, engine speed and direction is provided with additional control of a gas shut-off valve and fire extinguisher for emergency use!
This 30 cc, Sealion engine was started by Fred Pearce, then continued by John Loveday and then completed by Nick. The original plans featured in the Model Engineer magazine in the late 1950’s. The combined work has taken over 50 years to complete.
