Miller and Tunnage – Double Ender

Miller & Tunnage – Double Ender
If you spend as much time as I do stalking wooden boats on-line you will have noticed the growing trend for work boat conversions, you either love them or not – me I’m in the love them camp. We do not know a lot about todays woody, thanks Ian McDonald, other than she was built by Miller and Tunnage in 1922, out of kauri, is 40’ in length, has a 9’ 10” beam and draws 3’7”. A Gardner 3LW 150hp diesel pushes her along at a comfortable cruising speed of 7 knots. Appears to be very well fitted out.


Can anyone put a name to this woody ?

18-11-2020 Input from Mark Erskine – I was interested to read about the above Miller & Tunnage Double Ender. I agree it’s a real nice boat and was interested to read about her Gardner 3LW engine.

Depending on the fuel and governor / rpm settings, the 3LW engines produce between 36 to 53.5HP from their 4.184 litre capacity.

The “Gardner 150” badge on the Miller & Tunnage control panel is for a 6-cylinder 6LXB Gardner (127 to 150HP) or possibly the 8-cylinder 8LXB (150 to 200)

Gardners are great engines and although the whole range are all low on HP for their considerable size, capacity and weight, they all produce a lot of torque at low rpm and are very reliable.

Although 36 to 54 HP seems a bit low for the size of the boat, I’m guessing the 3LW is a good match for a double ender hull because torque turns the prop rather than HP and the 3LW should also be very economical to operate at 7 knots.
