A Photo & Discussion Forum for Wharram Design Enthusiasts
I notice there is a curve on the hull of the Pahi and Tiki designs, can anyone tell me if this curve has been added to the classic designs. (Tehini). I have the study plans for the Tehini and it shows the bulkhead profile as having straight lines and no curve. I have emailed Wharram but can't get a response.
Good day Brian, I have checked the sides of my boat with a straight edge, & yes they are straight, just like the study plans. hope this helps. Although mine is probably one of the older plans, not sure if they have altered the newer plans.
yea my guess as well , ELSEWHERE.
When you start making changes in the shape of a stitch & glue plywood hull, it's like working with a bowl of spaghetti, you pull one strand, it moves elsewhere. At the very least, if you put a curve in the bulkheads, and camber in the sides of the plywood hull, you'll make changes to the shape of the sheer line. What you may discover is that you've created a shape that can't be covered with tortured plywood. Too many conflicting curves to get the plywood to lie down properly.
Customizing and personalizing are OK in anyone's book. Changing the basic design is a different matter so adding bridge decks and changing the hull shape in my mind changes the boat so it is not a Wharram because quite simply it becomes your design and not his. Anyway its a free World and obviously Wharram does not license his plans like designers such as Brown/Marples or Simpson so that you can only change it with his consent. I guess in the self build business that invites people to tinker and produce something the designer never intended. Trouble is it also gives the designer a bad name because people look at these creations and say "look at that Wharram" and "it is so ugly" or "isn't that thing pitching like crazy" "or I'd never have one of those" when if they saw a lovely vessel built as it was designed they may be very impressed with the design.
Personally I love Wharram's designs but I cannot say I love all of the boats I have seen apparently based on his plans!
I am sure that with the good advice you can get on this site and good sense of either going to Wharram or another designer to get them to professionally modify the plans to get the boat you want, you will build a beautiful seaworthy boat!
Best wishes and good luck mate!
