The only model yacht plans I have was the PANACHE, now held together with cello tape, so it became base camp. From my experience of sailing Blue Boat I wanted a more stable model, especially if it was going to carry electronics and sail on larger lakes. I am aware of Universities building autonomous yachts to sail on the open sea, but that was beyond my budget. Panache MM1299, Product Code 21052 @ myhobbystore.co.uk.
The easiest way to make the boat more stable was to make it bigger. So my objective was to scale-up the plans to be twice the size, twice the length & twice the width. Compared to Sun Sail yachts, Blue Boat was fairly narrow and thus heals over. All yachts clearly heal, but to make the proposed boat more stable I decided to scale-up the plans to be 2.5 times the width. Pressing a few buttons on a Scanner and folding the plans in several directions, produced the A3 plan I required. Compared with the aerial view above the boat below is clearly wider, less of an ocean racer now.
Once the Plywood arrived from Wickes I proceeded to cut out the bulkheads and backbone from the A3 plans and having drawn around the plans then used a jigsaw to cut out the pieces. The bulkheads were slightly altered from the PANACHE plan to have cabin superstructure. The initial assembly is shown below.
