A couple of months ago a friend asked me to design and build a small generic tug as a christmas pressie for his 6yr old son. So out comes my trusty old CAD programme. cost as always was prime factor and build simplicity. I used the TID tug idea of not having any compound curves and to provide bomb proof strength used a frame construction. the end result is a passable representation of a harbour tug of a certain age and thanks to the frame construction has virtual unsinkability. the power comes from a 400 class motor geared down 2:1 with a pulley drive running on 7.2v . Vital stats are 465x165x165mm draft is 45mm and displacement is a miniscule1.115kg and joy of joys testing in the bath shows perfect trim as designed no additional ballast required at all

Well thats my 2p worth so come on chaps & chapesses what offerings have you all built from the drawing board up.

Well done mate it looks a real treat , very nice ! i am currently working on plans for a fishing boat to my own design as well as building the altair ,(scottish pelagic fishing vessel) What is the cad programme you refer too and how does this help and lastly where would i get it and what sort of cost ?

Hi Andy the CAD prog I use is “solid edge 2d” its a fairly simple 2 dimensional computer aided design programme and is easier (well for me) than pencil and paper as dimensions can be tweaked in real time without an eraser (google “solid edge” its a free dowloadable programme) and it uses no paper untill your sure its right. most people don’t have an A0 printer I agree but if you google pdf printer you will find several programmes that act as a printer and save what your printing to a pdf file that most print shops can scale to whatever size you want. my local shop charged about a fiver to printout 2 copies of these plans (2 sheets each) at A1 all I had to do was email the file to them and a day later go and collect the plans. now a classic fishing boat there’s an idea

if your not familiar with CAD then take some time to play with it and see what it can and can’t do there is an online help centre and a self help forum which I found pretty useless but persevere and it all starts to fall into place. one tool I took some time to find and is arguably the most usefull in model boating is the mirror function it allows you to work out your plan view on just one side then mirror the lot about the centre line also make sure you set your default units to at most 2 decimal place’s or at the size of drawing we use its far to accurate I use mm set at 0.1 accuracy then when taking measurments from the plan round .1 to .4 down and .5 and above up.

hope this helps you will have a few headaches but its worth it in the end

Hi, I have just come accross Phil’s thread start, interesting stuff.

I have just finished drawing up a side view and plan for the German WW2. Commerce Raider ATLANTIS.

Not knowing how to design using a computer, I have drawn it using pencil and paper ( the paper being the reverse of a plainish wall-paper roll taped down to a piece of ply-wood ).

Knowing the overall dimensions of the original I scaled off of all the photo’s I could find either in books or on the net. I did find one plan offered for sale but only after I had been working on mine for about a month.

The hull is an accurate deck view but the profile of the hull curvatures will have to be a best guess given I have a stem angle and stern type from the photo’s.

This is my second model ship build, the first being a semi-scale steam harbour Tug so I am finding out how to do it as I go along.

To give others some confidense, If I a beginner will have a go why not a more experienced builder?

If you design / draw it yourself it will be not only unique but a very satisfying to sail.

Who else is doing this sort of thing ?

The beauty of building from your own plans you can have a unique model, and not follow the heard. All my scale models are of boats with a connection to me personaly. I have drawn detailed plans to the size of the model, or in the case of old sail boat just drawn the frames, stem and stern posts. then marked out a keel and built as the shipwright did before plans were used. view some of my work in albums probably on page 2 or 3.

Hi Geoff and Ken welcome and have to say all the reasons you give for building this way are why I’ve got hooked having almost completed my 1st own design I’ve already got more ideas bouncing around in my head.

Hi Geoff I have to agree with Andy some impressive work there. I’ve just realised that I have another boat that may well fit the own design cat it’s my Homewood landing 24 which is still a work in progress the story here is that I found some computer generated images of a planned full size build and using those drew up my own plans at 1m the 1st full size hull is nearing completion I believe unfortunately the promised info on the build from the guy in the states hasn’t been forthcoming so I’m just continuing as I see fit

any way here she is

Thanks guys. The hull above looks very good too. The paddle steamer was my first model boat made 2001-2. The storey is when I was about 8 or 9 sailing a model yacht my father had built, on the pond was a steam driven model of a paddler and I thought I want one. It took me 53 years to realise the dream. I built the Glen Usk because I sailed from Weston Super Mare on her about 1960. Keep up the good work . Geoff

Most of my stuff is self designed.

I would be embarrassed to let anyone see my “plans” , and work mostly by making it up as I go along. Shorty was a simple three view copy of a Sunderland line drawing, and the rest was just an idea I had in my head….you cant get much more basic than that!

Actually, I am not sure I even USED a plan for the Toyboata, just a crude dimensioned sketch and a lot of lines drawn on the plywood I used to make it with in order to get the proportions right.

Even if i have a plan to start with i only use it as a guide.

Ok, the two MFA boats were fibreglass kits but thats the only two like it in the collection!

Thanks for that Geoff the rest of her is here I’ve a pretty good Idea how that goes Ashley some of my best porforming aircraft models where built without plans. and to be truthfull the plans I draw allow me to think the construction through before hand and often save on wasted materials but don’t get refered to very much once the basic hull is laid out.

Yes Ashley thats the method I use most of the time. I built the Flying Foam from a plan about 3″+2″ I did enlarge the frams on the computer, When the lines where a 1/4″ thick I traced through the ceter and enlarged again. Until I had the requiard size. Then traced again. Geoff

All pretty much as I suspected because we all build one offs most of us don’t bother to much with formal plans. any way a quick update on the tug not a lot left to do now. lights, tow hook and bollards should do it

not wanting this to turn into a build blog (whatever that is) just thought I’d stick one last pic of the tug now in its own carry case

thanks for that Bob it was decided that a box would be the best option for a 6yr old to save any damage getting it across the park and to help him carry all his bits a once it will fit nicely onto a trolly for him. Can’t wait to see the lads face his birthday is the day of our clubs night sail should make his day.
