Fijn middagje surfen. Eerst bij de dammetjes gekeken maar dat was niet veel en te veel Noord. Toen naar de dijk. Daar was het niet veel beter maar de wind nam gelukkig ietsjes toe.
Had vandaag vast en zeker sneller gekund want toen ik het board uit het water haalde zag ik dat ik met een gespleten vin die naar buiten stak had gevaren. Gek genoeg niets van vernomen.
