You could buy and build another Master Korabel boat kit which is narrower. I also used a MK kit and had to choose one in which I could keep the hull size but change the number of thwarts and other small details to change the scale a bit.
As to the scale of the SF II model, you may look at the sailor figures in the kit and check to see if they are actually 1:72 or different.
