even-keeled Posted May 12, 2017 Report Share Posted May 12, 2017 Hi, I am completely new to boat construction and have never been in a sea kayak. However, taking a 75 mile journey in a tandem Hobie pedal kayak piqued my interest in kayaks. I'm an airplane mechanic and a fan of vintage plane construction. I like the design of these Horton boats, especially the Poco Barta. I've lofted the offsets onto paper templates. I like the idea of the kudzu comfort frames but the original offsets don't include the split design of the forward coaming support frame(9'3"). Using logic from Nimrod offsets and Poco Barta data, I made offset data for a lower mid-coaming frame. Is it appropriate to post those offsets here for review? I noticed later that the Poco Barta on the book's cover has this Incorporated and an additional mid-coaming frame that secures the forward end of the floor boards. Also, I tweaked the design of frames 5'6", 6'5"and 9'3" a bit. Can those be posted here as well? Thanks Quote Link to comment Share on other sites More sharing options...
Kudzu Posted May 12, 2017 Report Share Posted May 12, 2017 You can post them. I do not support modifications because when you start changing a boats design, strange things can happen and it is no longer my boat. 2 Quote Link to comment Share on other sites More sharing options...
even-keeled Posted May 12, 2017 Author Report Share Posted May 12, 2017 I understand the risks of deviating from the engineering. I'm not seeking approval, just sharing ideas.With these, I'm attempting to reproduce the middle frames as seen on the book cover while keeping the frame openings larger. All original offsets unchanged except frame 9'3" lower removed as on the book cover.https://goo.gl/photos/cf6fByaYPB2VLhZK8 The extra frame with offsets https://goo.gl/photos/i8T6mxqBrsJSoZ1c8 These two simply have the fanny beams horizontal https://goo.gl/photos/nL7qp3b3FKKaHESJA https://goo.gl/photos/wb42cXeTN9qdhjNTA And the top of 9'3" arched up instead of down. Bottom sides omitted. https://goo.gl/photos/AaoJdL18vSX6po3v9 Quote Link to comment Share on other sites More sharing options...
even-keeled Posted May 13, 2017 Author Report Share Posted May 13, 2017 My thought process here hinged on the front cover photo being the Poco Barta. If that is a Sling Shot then I am mistaken and I agree that cutting the 9'3" as shown would need further research. Thanks Quote Link to comment Share on other sites More sharing options...
benhardt57 Posted May 13, 2017 Report Share Posted May 13, 2017 Being a designer myself, I understand the allure of making changes and "improvements", but with so many Kudzu designs surely you can find one that suits you. I did, bought the plans and am very satisfied. Everyone is motivated differently, though. Good luck with your project. - Ben 1 Quote Link to comment Share on other sites More sharing options...
Kudzu Posted May 13, 2017 Report Share Posted May 13, 2017 I am going to break my usual silence on changes, but if you arch 9'3" you are going to have an 'ugly' hump in your otherwise clean lines of that boat. There is a reason I don't arch them like that... it's ugly. Quote Link to comment Share on other sites More sharing options...
even-keeled Posted May 13, 2017 Author Report Share Posted May 13, 2017 Thanks for your wisdom. I now see that this Barta will be great as designed. Quote Link to comment Share on other sites More sharing options...
