Thanks for input to this point. I'm blessed/fortunate to have paddled many singles and own a number just want to add and refine the fleet. I far prefer the comfort/feel of sof to hardshell and while I love my fiberglass tandem performance but its weight and comfort pale to my own experience in sof tandem. The hard to find Ladoga sof Russian tandem I owned some years ago was fantastic-- I introduced scores of people to paddling in its front cockpit before its materials failed beyond my ability to repair (great design, inferior ingredients). It weighed 62# and performed well though I was expecting a nonfolding sof in lower volume design could go under 50#. I'm a fool for not recording offsets before that one was disassembled for last time. So... I've experienced great tandem performance in sof and want to build a replacement. While waiting for Kudzu to offer plans for a true performance tandem (no paddle clash), I may go w a rec boat either converting another old frame I have or mess-about or chuckanaut15 modification. I am interested in the anthropometric approach but have no experience w/ steam bending ribs. I did note that capefalcon uses same approach but would like someone to point me to a detailed instructional on that technique. Cheers.

Thanks. Maybe best I get familiar with software that lets me start w existing design and tweak to gauge impact of effects on perceived stability. I haven't used any of the hull modeling programs but think I probably should and put something less ambitious like a c15 or similar in the project q. I did expect to upsize stringers and probably let a symmetric middle swell a bit from the single design, perhaps scaling middle stations up to get a wider midsection advantage of a fuselage style is you could almost eyeball what looks to flow appropriately in curves, but would be elegant to do this fairing in software first.

I have built a SOF and S&G single and would like to build a SOF tandem. I had an old russian one I wore out that was more comfortable than any plastic/fiberglass/wooden boat of various design that makes my sometimes seasick prone wife far happier in any kind of chop. While delighted w/ the performance of my old Ladoga 21' x ~30 " 62# boat (excellent design, inferior materials) and my used point65N doubleshot 20'1" x 26" 84#, I'm interested in building something ~18' x 25" day tripping low volume tandem SOF and hoping for <50#. Capefalcon mentions adding 6' to his 14 x 23" and happy w/ result. He does classes and customs, not plans. I was looking at various yost-style SOF singles in the 13-16' x 21-24" and considering scaling up myself (easier, I surmise in fuselage frame than in falcons more traditional build). I've seen only one set of plans for a MC baidarka in tandem (paddling light) and am personally disposed to 1-2 harder chines and something a little leaner. Q's: 1. has anyone got any advice/pointeres re: problems I should anticipate? 2. anyone else ever done something like this? 3. am I crazy? Thanks in advance.
