I've used both internal and external strongbacks, and my experience has been that lining up the forms on an external strongback takes a fraction of the time an internal one does since you are working from a dead straight, stable platform, and you don't have to try and slide forms from the ends which is time consuming in itself. The other thing I found is that to slide the forms you have to make the opening slightly larger than the strongback to slide them on which means to get them to line up properly you have to not only adjust the horizontal but also the vertical and then fasten the forms to both horizontal and vertical cleats. This is very tedious when compared to simply clamping all the forms to an external strongback, running a string or laser, taping the forms into alignment, and nailing to the external strongback and you're done. The vertical aligment is already fixed by the strongback, so the only adjustment required is the horizontal plane. It used to take me at least a day to get the internal system mounted and lined up properly; with the external I have the first 4 rows of strips on at the end of the day. Plus as Bill mentioned, the external can handle any length boat over and over again. I have used the internal strongback over again as well, but it has to be modified much more due to the different lengths of boats, unless you only build one model over and over again. I've build a 19'5" Black Pearl, 18' 6" Cape Ann Expedition, 16' 6" Redbird canoe, and a 16' Iggy on the same external strongback.
