Someone say DW foiling? Nothing better than the EGG!!!
www.oneoceansportsaustralia.com/shop/the-eggTheses boards are made for DW, plus they are crazy light and strong as anything on the market if not stronger and cheaper!
Can you DW in the conditions you have? yeah for sure it sounds like quite fun stuff. Your bumps sound pretty slow so get a big foil wing to start with as you will want some lift. Make sure you work hard on your paddling technique as getting up DW is really 90% technique and the better you can feel the water the easier it all becomes.
What you want to do by wind winging up wing and then paddle foiling DW sounds great but it does make things harder, having the wing on your back which is most of the time wet can really throw you balance out of wack so keep this in mind and to start with I would suggest to try it with no wing on your back.
Having the right gear does make life much easier and when it comes to DW foiling having any disadvantage just means extra pain!!
Feel free to ask me any questions you like as I will give as many tips as i can to help!!
