    Oh Mate.........

    from 45 to 40, then 25 to 28, then 40 again............

    from steel to FC, to FAR, to steel, with some thoughts about other choices...

    Ok, that is your way, and for sure it is your right to do it that way.

    Just one comment regarding your own @ss:

    Do never, never, I mean do not think about it, try to make a stern tow with such a boat!!!!

    Pushing is ok, towing on shoulder can be ok, but never do a stern tow!

    N E V E R

    Even if the boat was designed to do stern towing, the skills needed to survive two jobs, are probably far, far away from yours.
    No, no, not hammering on your expertise, just to make sure you survive the first month after launch!
    Tugs, Anchor handling vessels, and Icebreakers are not toys, nor yachts. You either know what you are doing, or life will tell you the hard way what you did not!

    Print that out and put it under your cushion for a while!

    Skipper I used to sail with managed to pull the shaft out of an anchor handler doing oil rig work. Got a line around the prop. They got the ship to dry dock before it sank though.

    He was back to first mate after that one.

    Sorry if I am repeating because i did nt read all the posts.
    Please be sure that the cutouts have a rounded corner of 5 to 6" radius. Sharp corners will cause stress concentration and may become starting point of cracks in future.

    Yes, tugs are speciality apart. It can go wrong even when very experienced professionals are involved.

    Last week one tug manoeuvring big cargo ship, capsized in the harbour of Rotterdam. Two lives were lost.

    Yes Richard it damn well is my right when it is coming to my time and money and I want to make sure i will make the right choice- so yes!! you are correct!! that is my right!

    honestly- I really dont care if i change it 100 more times!!- if someone wants to point that out as if there is something wrong in doing that !?--take a guess who's problem it really is?!...print that out also and sit on it...:p

    i dont think its fair to the thread starter to talk about this stuff on this thread...i have another thread you can come and (try to) make me look stupid on but here(this thread) isnt the place...

    wow- did they get overtaken by thier tow?
    happens a lot--especially if the tow gets abeam of the tug. was it towing it astern? or was she assisting? when towing astern thats very dangerous since you can't cut the towline- and if you could release it instantly the rebound would kill you.throw you overboard, capsize you or both-
    the way to handle that would be full astern backing into the tow...after a certain point --youve lost her--and its all up to the forces at play whether you survive. if the tow is bigger/heavier than the vessel--its not pretty

    NB: life is a risk no matter what you do--there are no guarantess in anything we do- so we can sit in a bubble and not try anything for fear of dying or we can live--and when our number is up--then its time to go...
    I feel sorry for the families of that crew...
