Harbour tugboat

horesko · #1 09-09-2006, 08:59 AM

Hi, everybody!

I'm doing a paper at the University of Zagreb about the subject in question.
Does anybody know what the body lines should look like?
Any examples, maybe?
Help me, please.

Thank you.

Try 'The Propeller Handbook" - Dave Gerr

Then,
1. Work out the job the tug is designed to to do - to pull how much ?, how far ?, etc
2. Calculate the power it needs to do this job
3. Look up the size of vessel it needs to be to accommodate this power.
4. Estimate the weight a boat of that size will be
5. Draw lines to these requirements
