Bit of background: I surfed a bit as a kid/teenager and after having lived inland for most of my adult life have started again at 38 and am loving it (although I'm right back at the beginning). Unfortunately, I broke my fibula a couple of weeks ago (not in the ocean) and have to cancel the 3 month surfing trip I had planned this winter. No idea how long it's going to take to heal enough for me to continue to learn to surf... but really want to get back in the water as soon as I can walk/swim.
Bodyboarding occurred to me, but I'd like to get out the back and not be jumping around on my ankle so much - for which I'm presuming I'd definitely need fins - also a no-go for my ankle. I'm wondering if bodyboarding on a Beater would be possible - basically, I'd need to paddle with my arms and then stay on my belly, so my question is. . .
How easy/hard is it to get up to speed on a beater? Am I going to fall off while paddling? Is catching an unbroken wave on a beater a wild dream for a fairly physically strong beginner? Does anyone have any deeper water no leg surfing ideas? Just laying around on my 6ft foamie did also occur to me although it might get depressing.
Thanks in advance guys
