The Beach Cruiser Mark III is the third evolution of the Beach Cruiser series:
The original Beach Cruiser is a purebred & simplistic Cruiser longboard, designed for premium wave catching, speed & easy flowing turns.
The Beach Cruiser Mark II adapted that platform, reducing speed and ease of turns slightly but introducing a user-friendly nose-to-talk walkable board for surfers primarily looking for a Cruiser longboard but want to be able to dabble with walking/noseriding.
The Beach Cruiser Mark III takes it another step: a more advanced & technical but extremely capable Cruiser + Noserider hybrid, for surfers who want both the premium wave catching & healthy speed of a Cruiser with the hang-10 capabililty, sensitivity & pocket control of a noserider.
The speed of the Mark III is on-par with the Mark II and handles waves slightly bigger and pitcher a bit better due to the increased rocker a narrower outline/nose, while the Mark II remains a bit easier in general in tiny 0.5'-1' ankle slapper days. The Mark III is an extremely competent noserider though, really giving a dedicated noserider longboard some seious competition. It feels very, very competent on the nose. It locks in more than the Mark II along with being more sensitive & reactive than the Mark II, so it naturally is a bit more advanced. But loaded with capability!
