Working directly with Claudio Diolaiti, and keeping in mind the “skinny” boats that are currently all the rage, he was kind enough to take his narrow deck design RG65 and draw up station shadows to allow a build of a new, lightweight ultra-thin design. The design, currently titled “nARROW5” was drawn to meet my requested criteria - being ultra thin, having chines, and having a rounded bilge to reduce drag in light airs, and slab side above the chines. The design he has put together has a maximum beam of 87mm and a waterline maximum beam of 84mm. He is proposing a total displacement weight of 1083 cm3 ! Not sure if I will be able to hit that target, but will give it a try.
If I run a bit “fat” during my build, I hope it will still provide me with an idea of the design, and it’s competitive possibilities. It may be that I will use the finished “wooden” boat as a plug for a future glass or carbon hull.
Claudio will, no doubt, want to add commentary to perhaps explain further his design - which I welcome. I was going to try to use a 500 gr. bulb, and he is suggesting a 609 gr bulb. Will see how it floats and if it is a very “tender” hull, I may try a slightly deeper keel…although it will all depend on how close to his suggested weights I can stay. Obviously I would love to come in less than projected and add some corrector weights to bring it up to his design specifications.
My plan is to post some photos as I proceed to stumble along. Since I am “almost” done with a major bathroom remodel, my time will be spent finishing that off first - so an early/fast build will probably not happen.
