North Rock tug
Today another fine morning to test out the North Rock a replica of a tug own by Alexander Towing Co. Ltd. haven't run in a while & I'd taken some parts out took a while to get it running on a even keel with some lead I had in my kit . The original tug was built in 1956 engine was 56 nominal horse power ( 1000 indicated horse power )
Liked by MouldBuilder and Martin555 and
re; "The original tug was built in 1956 engine was 56 nominal horse power ( 1000 indicated horse power )"
What is the correlation between Nominal Horsepower and Indicated Horsepower?
Thank You.
