A subsea riser support buoy is disclosed having a riser support member and a jumper support member that extend generally parallel to each other and that define a lengthwise direction extending between them across the buoy. Pontoons extend lengthwise beyond the riser support member and the jumper support member to provide attachment points for connecting tethers to the buoy. In this way, the attachment points are spaced more widely than lengthwise extremities of the riser support member and the jumper support member, beneficially altering the dynamic behavior of the buoy and especially its pitch characteristics.
