    This beautiful sailing boat was left to our club, but was not taken by anyone to be finished off as it was nearly completed.She has a lovely made box for transportation, this was where she was when I acquired her. The hull was complete and the rigging and masts were all jumbled up. There was no instructions, but I soon unravelled the mixture.the sails were still in a flat sheet of plain cotton. I used these as a template to make new from left over cambric cotton. Once complete I staged a test sail which went very well, except the twin props would not power the vessel forward in even the slightest breeze. At first I thought the props were too small, but it turned out to be the belts slipping. I changed these for new and the problem was cured. A few other tweeks were needed and now I have a cracking sailing boat.

    Rogal,
    Thanks for clarifying the prop question.
    I will keep your experience with the setup in my organic computer for future reference.
    I wish you fair winds and following seas.

    Hello Rogal,
    It's always nice to see that the personal touch is added to the existing plans with small changes. This gives the finished boat its personal look (see the cutter โ€œAlineโ€ in my harbor). Self-built boats are even more special, but let's not get carried away, shall we?
    Good craftsmanship,
    Your landlubber ๐Ÿคฃ๐Ÿคฃ๐Ÿคฃ๐Ÿคฃ

    Good morning everyone. Re question by BarryS. Yes I believe the original builder added as an extra the small twin props. This I find is a great help when sailing on our small pond, about the size of 2 tennis courts,, the props are 25mm 2 blade and each have there own small brushed motor with belt drive. At first I could not get any drive forward even in the slightest of head wind, and did contemplate fitting 3 or 4 bladed props. But instead swapped over the pulleys from the motor to the prop shafts, hoping to improve the gearing ratio from approx 3-1 to 1-3 . This didnโ€™t have any effect either. Then I had a thought maybe the props are not really turning efficiently and had a look at the rubber belt drives. These were small loops of rubber about 30 mm diameter with a cross section of around 1mm and were very stretchy. I had a box of assorted rubber seals bought from our local supermarkets middle isle, amongst was a 30mm diameter one with a cross section of 2mm and not as flexible. These fitted perfect and tightly onto the pulley grooves. Bench testing seemed to be satisfactory, so I couldnโ€™t wait to go to the pond. At the pond the breeze was quite a stiff one as they say, so this would test the power train. Perfect, could not be better, at full power the speed was quite gentle and scale looking especially into the breeze. Once turned about the sails took over and the motors were not required. I had worried that she may have been to fast and unrealistic under power, and I always had the option of changing the gearing back to the original, but have not bothered. The stiff breeze showed up other problems. I have dealt with these though in other blogs. Thanks everyone for your interest, just waiting now for the 3inch ice covering of the pond to melt.

    Rogal, excellent rebuild on the Karoline. I always enjoy seeing boats brought back to life.
    I have a question, since I am not familiar with the original or model. I notice that the picture on the box does not show a propeller.
    Did the original builder just add those to the boat or did the original sometime in its life have an auxiliary engine? ๐Ÿ‘

    Hello Rogal, great purchase and fantastic restoration of these model.
    It seemed that we had already talked about it in another topic but maybe Iโ€™m confused.
    Congratulations for the photos, itโ€™s incredible but the eighth image (the penultimate) looks like a real boat.
    This is not the first time you have succeeded in reproducing this effect.

    Lovely job well done, surprised there were twin props though. Just noticed the small print on the magazine. Potato boat, that will be the noise the engine makes. On the Billing Mary Ann the full size boat could be heard long before you see the boat as the engine was so loud.
