I love pleasure modern boats with engine. The world of naval model-making doesn't put online many plans on them. I have got a technical training and working in engineering consulting firm, I was interesting by the conception of reduced model. I studied then drew several models at 1/18th scale. I like the indoor and outdoor design. That's why lot of these boats are completely lay out.
All of them have been already made, some in many copies.
I suggest you these plans in format DWF A0 in size 841x1189 mm, and their cut-out in format PDF A4 210x297 mm, the printing is at your expense. The big size A0 require the use of a plotter. You can find this in reproduction stores or in engineering consulting firm. For the formats PDF a classic printer is self-sifficient. It's you after who restick the plans to reconstitute the first big plan. Personally all of my boats have been made with these A4 plans without any concern.
From receipt of your payment I send you by email a informatic file with all of plans, a materials listing necessary for the building and some pictures.
You can also watch, to help you for the making, the differents pictures reports in the heading "reportages construction" or on my site:
Regularly I propose to you new model
