Hi mickeyb,
i am same weight have a 10' mana can go flat water paddling with my 8 & 6yr old on front they love it & am saving up for grom boards for them.The mana also is fun in small surf super stable but you will not be able to stop with one board once the bug bites you will want a smaller board for in the surf when it picks up im at that stage know.good advice i have had from crew on seabreeze is demo as many boards as you can.enjoy.calbs
