Dave,

This is totally doable. The front of the boat won't change but you will have to alter all the ribs behind the middle. The middle one may need some additional bevel as well. Do a 1'=1" or better yet 1.5"=1' model from poster board to get the shape right. When it looks right you can get some fairly accurate bevel measurements (especially on the bigger model). Then start building mock up frames from cheap 1x4 stock until you get it right. I doubt the rear stem will have the same bevel as the front probably a little less.

Good luck.

Mike

Thank you Mike.  The plans that I am using do not have ribs but rather 3 building forms (the longitudinals are then attached to the forms and the stem at the bow and at the transom form).  Would you think that I would need  to alter the building forms or just try to shape the longitudinals and outer planks to the shape made with pointed stern?

Thanks again.  I truly appreciate the feedback.

Dave

Do this...it will make you wonder why you paid for plans in the first place. Make a model out of posterboard. 1"=1' . Cut the side panels to scale to the shape in the plans, as well as the trapezoidal formers. Make 2 sets. Mark the side panels to scale where the formers go then tape the first boat together. Looks like a mini boat. Do the first one as per the plans. Now take the second one and modify the panels to your liking. You could try to do the second one standard without side panel modifications and no transom and compare it to the normal one. Now make another set of panels with more modifications to get the lofting looking correctly. You may need to cut more or less transom angle, or modify your trapezoidal formers to get the best profile. Do this a few times and youll wire in the lines. When the model looks good go build it in the garage full size.

I own a hankinson 16' drifter and its a good boat. Mine was a high side originally but i cut it down. I cut it to 24" at the locks. I would reccomend doing the same, trimming the panels to fit out of one 4x8 sheet apiece. Youll save wood ,money, and wasted energy trying to row into the wind. Additionally, the hankinson does not have a wide beam or alot of flair and consequently doesnt have alot of rocker. The stem and bow angle on the design are good, but the flair is not enough. If i were relofting the boat i would add more flair at the oarlocks. Compare beam dimensions on other 16x48 driftboats and use those dimensions as a starting point to make a trapeziodal former for the center. You can then reloft the other 2 formers to match. Check the rocker of the new models against the original and compare..10" at transom and 12" at the stem off the floor are generally the rightamounts. To make the side running boards and get the fair curve, once you have the hull built from your lofted lines, try storyboarding ... measure lengths and angles from one point to various actual points on the hulls sidewall. Than take those notes and transfer them to a new piece of plywood and cut your panel. Perfect fit. You can read more about this on fretwater lines
