Omar can connect you with paddlers and groups in the area and can help you demo and find boats if desired.
Anytime you’re riding shorebreak yes, you need to be wary of hitting the bottom and pitchpoling, and also a helmet is smart if you think ground contact is possible. If you pitchpole, boat damage is likely so try to avoid the extreme shallows.
