Kodiak by Todor Adamov, Varna, Bulgaria

Updated September 29, 2018 Few pictures of my Kodiak under spinnaker rigged as genaker wind 7-9 knt approaching Varna . The boat is performing very well at this wind force, very stable. I have left the wheel for 30 minutes talking with friends in the cockpit she is not moving from the course. Next season I will rig the boat with Code 0 or genaker for light winds up to 10-12 knt. This one is 30 m2. Thank you for the extremely good design, the boat is performing exactly as expected for the boats of this class. You can see docking the boat for winter, test of emergency steering by my self. Please note how good is the cockpit for the climate here is perfect, very safe . Updated July 17, 2018 This design is great for sailing in our area , Black sea. Now the boat is fully equipped with mast, main sail, lazy jack and bag, Bimini and looks beautiful. We have tested the boat up to wind 25 knots under main and Genoa she is performing excellent, average speed down wind was 5.7 kn, which means at some moment she was running with 6.8-6-9 kn. She is not taking water, the stern is going up and down, the motion is very comfortable. The cockpit as modified by me is very big, comfortable and very safe. The only problem I experience is the drainage of the cockpit, the height from the level of the cockpit to the outlets is only 178 mm and some times the waves splash into some water, unfortunately I have omitted the overboard valves on this place, which not typical for me . Under engine she is performing as expected at 3000 rev WOT, she is making 7.8 kn normally I am operating at 1800-2000 rev with 5.5-5 kn. Generally speaking the boat is performing exactly as expected from this type of boat and exactly as described in the project manual. Updated 11 October 2016 Here are a few pictures of my Kodiak at Varna bay during the Tall Ship regatta parade of sails. The mast is due to be fitted in the next few weeks. The boat is doing 7.1 knots at WOT, Volvo Penta 28hp, D1-30. Cruising speed at 1800 -2000 RPM is 5.5-6 knots. I have tested the boat at wind/sea 4-5 B, she is performing very well, even with missing loads i.e. Mast anchor chain etc. The rolling is normal and comfortable. The steering is perfect, even with following sea, stays absolutely on course. Astern, also the steering is very good, you may steer the boat astern straight as long as you wish. I will keep informed in the future. Once again, thank you for the perfect project. 11 April 2014 A few explanatory notes: Hull design : I could not find locally and in EU C Flex ,so I have decided to replaced it with 3 layers of mat 450 gr/m2 and one layer of woven roving 600 g/m2,compensating C Flex thickness of 3,17 mm.( See David Gerr book boat strength). So I have changed the form building. I have covered the matrix with expanded PVC - PVC sheets with thickness 4 mm, easy to bent and taking nicely the hull form as you can see on the picture. Then was very easy to remove it. Finally, obtained hull thickness is as required by the LR Rules and project instructions. Polyester resin was used. Second major change is the stern. I have decided to do it as a trawler stern, overhanging, not changing the WL length. Now I have an enormous cockpit, very well for the Bulgarian sun and hot climate. The hull after fairing looks like a hull from the female matrix at least the sides. It took me too much time. The wood involved in the boat is only mahogany marine type as meranti, sipo and sapelle. The wood is encapsulated. The plywood is a marine type certified by RINA deck is OKUME, marine grade, encapsulated with polyester resin. After a flex teak deck will be fitted (this artificial teak). The deck and superstructure will be encapsulated with mat and fabric as per project but I will use venilester resin. The other change I have made to the project is that I have omitted the raised forecastle deck as you can see on the picture. The engine is Volvo Penta 28 hp as per project. I am intending to insulate the ER with first class marine noise insulation. Mast and boom is Z spare, aluminum, brand new, complying with project requirements. Sails are available. Superstructure windows are aluminum, marine type, imported from Turkey, Boffort. Ballast is lead; I had a problem I could not fit the lead blocks to the required height, but I will look at the problem after launching, I am intending to carry out an inclining experiment. Maybe I have to fit about 120 kg aft frame 3. Anchor windlass will be fitted on the forecastle deck. Do not ask me about the launching date, but I am expecting to do this job sometime in September?? After completion of sea trials I will send you all performance data. I believe that this boat will be the best motor sailor in the Black Sea area! Navigation equipment will be Garmin, not so complicated; only VHF, echo sounder combined with chart plotter and AIS compass. Hydraulic steering gear Hydroflex is ready to be fit. In case you are interested I may keep you informed about building and will send more pictures. If you wish so you may publish and comment the story/pictures in your site. Next time I will send picture about turning of the boat. My best regards, Todor
