I agree that I could imagine wanting to go a bit bigger yet than 17.5’ to “solve” for my family. Truth is, I also have a 4 year old boy too (so it’s three total) and he’ll come along soon. At some point my twins will paddle their own boat, but in the meantime these larger boats might hold a little more allure:
I’ve never paddled anything so large, save for war canoes, but those are a different breed entirely. How hard is it to turn these freighters, especially without a strong bow person?
