Hired a boat from them yesterday - a simple 16 feet angling boat with 10HP engine.
Was a nice trip - me and 3 more lads fishing across the shoreline on 7-9 meters depth with feathers/jigs.
Took 2.5 hours to find a good spot and 1.5 hours to land around 30 small cods, 40-50-ish cm long.
No mackerel

If you go there - beware of the crab trap ropes - we caught one with an anchor and it was pain to free it.
