What character is this? (yu2)
Yes, it is 踰 (yú): exceed, transgress, cross over. It is a variant of 逾.

Characters are sometimes rendered differently. In this case, the phonetic is 俞 (yú), meaning "boat", and the bottom part is written similar to seal script style.

Originally, the 月 and 刂 in 俞 were 舟 (zhōu, boat) and 巛 (chuān, water), and the seal character is a transition in progress. Another evolutionary bastard is  (containing 舟 and 刂), with the same meaning.
