    The main thing when welding anything critical is to keep it clean, contamination is not your friend

    Interesting that you mentioned stainless steel, I am not sure but I think that I have read somewhere that stainless steel doesn't work very well for boat hull. I think that the issiue is galvanic corrosion or something similar. I really cant remember what is the issue with stainless steel boat hull but (if I remember correctly) there has been built a stainless steel yacht and went to the botom of the sea pretty quickly! Also never seen one in real life. Otherwise it would be perfect hull material. As I said I may be wrong.

    Dear SteelT. Go through this thread and Daiquiri allready replied and explained problems of stainless. I will allso recoment you to check threads with biggest number of replies here in metal boat building section and you will find all replies to your strangest questions. Especially i recomment you posts of user WynandN. Unfortunately it seems steel in this dimensions is little bit overkill, aluminium will be probably better. I am also looking for something up to 8,5 m x 3 due our river waterways lift capacity. Not so much designs to choose from. Look at Fred Murphy tugyacht from GlenL.

    Mr. Steel.T is perhaps not so proficient with this forum, so I would suggest the following threads as the most relevant ones:
    http://www.boatdesign.net/forums/materials/stainless-steel-boat-possible-11519.html
    http://www.boatdesign.net/forums/metal-boat-building/stainless-steel-boats-53611.html
    Hope it helps.
    Cheers!

    P.S.
    Chase B, with no offence intended, please try to avoid inserting a consecutive series of single-line comments. It makes the thread poorly readable, so please try to gather the phrases in one single comment. If you want to add a new phrase to your latest comment, you can always use the "edit" button at the bottom right side of the comment box. Thanks mate. :)

    My original question is about 8m steel boat. And beside the link to Bruce Roberts who is very known designer but his boats doesnt look like pics I posted, thread drifted to stainless steel. It wasn't me who first mentioned stainless steel. And its not me who is interested in stainless steel. So why the f are you lecturing me?

    What's wrong with you dude, stepped out of bed with the wrong leg ?
    People are trying to give their opinion in a polite way, no need to get rude and IF you need to be rude, adress it to the people you have in mind....idiot.

    I found also Transition 18-20 ft from Clarkcraft.com
    not exactly like requested designs, but in steel (or aluminium) and under 8m.
    Saw somewhere somebody mentioned these plans are rather obsolete and not good for inexperienced builders but i didnt saw them personally.

    For some applications, building small steel boats may make sense, but most people just baulk at the thought of a high-maintenance hull material.

    Are you sure that maintenance issue concern is valid in epoxy era?

    Tar Epoxy was all the rage for a time, but outlawed ?

    It seems people around are using epoxy primer, epoxy coat and sometimes polyurethane as last coat. I am speaking about fresh water environment. Usually Jotun, Hempel or International, often applied by airless paint sprayer.

    I will definitaly prefer aluminium and its low maintenance but think that steel will serve better in our rough environment with lifts, crowded locks, rocky shoals , crazy barges and drunken fishermen ramming everything around. Unfortunately.

    Fresh water obviously less hostile, careful placement of rub strips to ward off abrasions that expose the bare metal, is a sound precaution.
