Board Recommendation

Stick with the foamy until you are 100% sure you are ready to move on to a different board. The more waves you can catch means more repitition of the basics ( positioning, popping up, generating speed) you get allowing you to progress faster. Learning as an adult requires basically committing to get your arse kicked for at least a year.

When the time does come to get a new board your still looking for paddling power, something that allows you to get into waves early and easily, lots of volume and flatter rocker. The earlier you can get plaining on a wave as a learner the more time it gives you to get set for a successful pop up and feet placement, which is the key to everything else you want to do on a wave.

In addition to the above, don't go too short too quick, i.e. avoid a 6' shortboard as your next purchase. You'll find your ability to progress will plateau significantly.

A number of people I've known over the years were too keen to progress to a shortboard, and whilst duckdiving is obviously easier than on a longer board, their ability to progress on the basics like being able to catch waves effectively, placing their feet correctly on the board consistently, finding the sweet spot on a wave, doing a proper bottom turn to set you up for the rest of the wave etc. all suffered greatly. All should have stayed on their longer & more bouyant boards longer to work on these skills, and develop a good style.
