I am at least half convinced. I am still focused on surf foil as purest pursuit, but winging has taken a hit, particularly light wind, as the efoil is pretty close in feel and so much more efficient and easy....get where you need to be in an instant, upwind work and limitations are non existent.
I suffered over the cost of this toy for a long time before pulling the trigger -- but I have had no buyer's remorse after. I see it as equivalent to a jetski or motorcycle in price, and it affords similar play opportunities.
The efoil has exceeded my expectations for fun factor. 1) chasing bigger waves, a personal tow in, get riding so early that it's doable and way less scary or intimidating. 2) maximized wave riding in short strike missions...half hour before work or lunch break, can get 20-30 waves, makes putting on the wetsuit worthwhile, 3) playing in tiny waves and boat wakes, loads of fun in off season. 4) wind swell riding, especially in off-setting tidal currents -- opening up spots otherwise not possible. It is one more toy in the toybox, but in the honeymoon period is getting a lot more play than anything else.
I haven't done much downwinding yet....but that'll happen. What I have done is shore runners with no wind, 10-15km of endless wave riding, drop in, get a few turns, kick out, get the one behind, over and over. The cool kids can do this on surf foil, with indefinite pumping in between....sadly I am not all that cool, so the e makes this dream a reality.
