Return To Lisa Maria

Lisa Maria

A Danish Fishing Boat some 50 Tons and 52ft long.
Hundested Semi-Diesel Hot Bulb Engine.
Lovingly being restored by Marine Enthusiasts.

Hundested Motor, number, 2470, model: FF/G/L. Year 1975.
This is the second engine of this type the boat has had in her life.

Engine particulars:
2 cylinders, 14 inch diameter pistons, stroke around 14 inches, developing
200 shaft horsepower.
Maximum RPM is 345 but we find that 250 RPM is very comfortable. Engine plus
clutch and gearbox weighs in at 6.5 tons. It has a 48 inch diameter flywheel
on the front.

She is fitted with a controllable pitch propeller which can absorb more
power than the engine can supply therefore at 250 RPM and full pitch we are
taking about 80% power off the engine. It is started with compressed air at 140 psi.

The engine was originally started with the use of chemical heaters, i.e.
fireworks, but these cannot now be purchased, I have tried "garden candles"
which can be used but we have made our own electric glow plugs.
These glow plugs are more or less electric heaters which draw 20 amps each
from the 24 volt supply.

The boat: Anchor Seine Netter, built in Streur, Denmark in 1942 and called
Lisa Maria, she is 52 feet long with a beam of 15 feet and a draft of 8 feet,
I believe she's around 50 tons deadweight. Hull is oak on oak.She came
to work in Grimsby in the early 1960's and then found her way to Eyemouth.

The Scottish owner died in the 70's and the boat was tied up. The boat was
used by people who knew little of the Hundested and it broke down. She was
tied up once more without the exhaust being capped from the rain, consequently
the engine became seized and water ingress to the crankcase did the bearings
No good whatsoever

We have taken 4-5 years of Sundays to strip and rebuild the engine and I
attach an article I wrote for the 40 plus fishing boat association for your interest.
Article link found at top of this page.

The boat is berthed at the harbour of Charlestown, which lies some 4 miles
upriver of the Forth Road Bridge on the Fife coast.

The engine has now run about 14 hours on her berth and on the 11th February 2005 we had
our first river trials. She behaved very well and were all quite elated when we returned to the
harbour. I believe that this was the first time in 20 years the boat has been under her own power.
This summer we hope to make a couple of trips down the river to Anstruther and the Bass Rock.

We are burning used cooking oil as fuel, this is a mix of 4.5 gallons of strained
cooking oil to 3 pints kerosene. We start on clean diesel and change over once hot.
