Glad to see I'm not the only eejit

Seriously though Matt might it be worthwhile to post a detail, enlarged of this type of panel set up, close to the area on the plans? I know 99% of pipple are gonna get it right. Those of us who's eyes ain't so hot any more might miss it and I'm sure a few would appreciate it.
Regards John.
P.s. When I made my goof, I just cut through the join and reset the angle correctly. Was very impressed with myself on close inspection of the inside my first butt joint

I'm always looking for ways to simplify the plans. But I'm sure I follow you completely.
Some more explanation?

Because the angle along the edge (bow to stern) of the hull panels is so slight it is difficult to pick up straight away, which way the angle goes. This has now been proven by me and Bob.
Ok, on most engineering technical drawings, fine detail is often shown inside a circle, say 2" diameter, within 6" of the intersection of an angle that is close to but not quite 90, or in this case 180 degrees, and usually magnified, sometimes even exagerated to prove the point. The circle is then joined by a straight line to a smaller circle around the actual area of the intersection.
Easiest way to display is: draw a circle, this is a clockface. From the centre draw three lines to the edge: first to 12 o clock, another to 8 o clock and finally one to 4 o clock. The top two segments are the panels. The line to twelve o clock would be the seam. The angle at the bottom is the
important information. This would readily display which way the angle goes.
IF: for example' the angle needed to have been the other way, then the lines would have gone to 12, 2, 10 o clock Hope this clarifies my point.
Regards John.

Hey guys, just read the last posts, great idea of puting a magnified detail of that bottom alignment.
I did make the bottom again and the boat is coming along nicely. the seams are filled and sanded and a saturation coat of epoxy went on tonight. I am looking forward to fiberglassing tomorrow. I have been getting lots of compliments already, its a fine looking canoe. I am getting maried on the 21st of the month and the canoe will be in the wedding. My bride and I have been woriking on it together and cant wait to display it at the wedding.
We hope to get it all finished and take it with us on our honeymoon to the oregon coast. This is a really great project. I am enjoying every minute.
Bob
