If you want to improve quickly, you do not want an inflatable. If you want a board you won’t outgrow quickly, you do not want an inflatable.
Those two goals are also in direct opposition of each other. The perfect beginner level zero kit is perfect for 10 sessions and you should make huge leaps forward during that time. Then you switch to a beginner aspiring to intermediate kit which will also give rapid progression and last one season. Then you get your third kit, an intermediate setup, that will last a long time.
Skipping gear levels or holding on to gear too long is a sure fire way to slow progression.
My first board was 8’x30” and 170 liters I think. I was self taught. Up and foiling day 1 and gybing day 1. I also took it to the ocean and caught and straight lined waves all day on day 1. I used that board for 10 days and then moved on. 85kg beginner with zero foil experience at the time.
this is super helpful, thank you !
