Unconvinced about the Kayak, Snags and break offs are extremely annoying when out on the water. Could work if you are able to anchor up in a clean spot of the beach.
I suppose, using a sacrificial stone sinker and hook would make it more fish able, it does look good. Might also scout it at over King low tide on a calm clear day (how often does that happen). If there are clear patches they are worth remembering.
Would love to fish where the Surfies go, but that would cause conflict.
Been told that this beach is the most productive one for Snapper in and around Kaikoura…
