I have no problem buying 3 plans for us if we can get it to 23ft and 8'6" wide. I have been in one of these and had a couple of guides that built them but with 5 people it doesn't quite have the room. So for us we need them 23-24 ft and 8'6" beam. They won't be trailers.

When could we get the plans on a stretched model. Actually the beam is fine just the length.

OK, that is somewhat easier.
I still have to redesign the model, add frames, redo calculations, reinforce panels etc. then draft all that.
I need about 10 hours for the calculations and 20 for the drafting but I must finish a couple other jobs first.
Let's say 2 or 3 weeks.

About the scale: when modeling (= design in 3D) on the computer, we do not use a scale, we design full scale. Later, the drawings are scaled to fit on paper, for printing.

Yeah I figured these are scaled to 3/8 it looks like.

the xf20 should easily be able to fish 3 or 4. Several xf20's as well as the similar older microdraft are being used as guide boats in the area. I'm building one for the same purpose.

All my paper drawings are to scale even those marked NTS but you should never take dimensions from a paper drawing and scale it up. All the dimensions necessary to build the boat should be on the drawings.
In the old times, you used a table of offsets to redraw the boat full scale on the floor and took dimensions from there. It is called lofting and was a long and difficult process because you had to correct the inaccuracies from lines drawn on paper. I have done it often and have found scaling mistakes up to several inches.
Today, we loft the hull on the computer with great accuracy, 5 decimals of 1" in my case. Or 5 decimals of 1 mm. It is all fair and correct, we do the lofting. If I forgot to show a dimension, post here and I will reply.

Where I live we see many flat bottom skiffs in the 22-24 range. Every now & then I'll see a 26 or a 28. Those are big skiffs...but there is a market.

Lots of them around here too. The big boys are typically work boats for crabbing or inshore guides. A few of the 24s are family fishing and party boats (Carolina skiff). I bet a quick build that could compete performance and cost would be popular around here.

Thanks for the good news. I would hate to put so much work in a design that nobody wants to build.

I don't think you will ever have that problem. Your designs are timeless.
