The double kayaks we use are wider and much more stable than single kayaks. To be quite honest, our double kayaks really take some coaxing to “tip and flip.” A water fight is almost always a guaranteed flip, so you might want to steer clear of that kind of stuff.
Getting in and out of the kayak on shore can also be tricky if the beach is steep. Our guides are there to assist you throughout your San Juan Islands kayaking trip with friendly, knowledgeable assistance on how to manage those infrequent “tippy” situations.
We typically average one tip over a year in our double kayaks and generally that occurs when somebody is horsing around. (I’m not sure how one really deals with “horses” in a kayak but you get my drift.)
