Precision Fitness has a Mega or Giant SUP Paddle Board designed for fun. It will take 6 adults who may be boring to happiness in a short space of time. Great for corporate fun or for the whole family. You decide .. Sea , River , Lake or Dam ? You can inflate the board with the pump in about 10mins with 2 adults pumping at the same time. When you’re done you deflate and pack away. More fun than that in a day is hard to find. The sea and waves can be very challenging so be warned..
