Isn't a yak-yak some sort of submarine? A paddled submarine? Were you trying to sneak into the San Diego navy base or something? Trying to find out the Top Secret stuff about the Navy's ironclads, perhaps? It won't work, Amos. Security is too tight, and if you were caught you'd face a firing squad. No bullets (they use Marines and they don't want them to hurt themselves), but a nuisance all the same.
