Both the 24 and the 26 involves the same steps, just a few more pieces of wood and will handle the same. We never seem to have enough room inside, the more we use one. But after going back and forth between the two sizes, the difference for me would be a bit more room for a head and shower in the 26 if you create a decent layout inside the cabin with about the same creature comforts for cruising and overnighting.
Now to speak about Ken and esteem builder of the Bluejacket, both are hard to live up to in their standards of excellence, creation and execution of boat building skills. I haven't updated my thread since I have been in the stage of laminating the sides, which is like building two boats in one with the cold molding process. So if you go this route be prepared to have plenty of patience as you see the boat take shape,,,,,,,,slowly. That's my recommendation to anyone that's never bit off a project with shape before.
And I recommend going with a slower harder for your larger glue ups. And be patient and let things dry enough before moving along to your next step if its related to your last step. Wet out properly all mating parts.
