There are a few charter operator there but Capt. Wewen Cs. are the most reliable and the most EXPENSIVE , around US$. 500.- per day , foods n drinks are excluded , tips are optional , based on 10 hrs max. fishing day . :P
There is a private boat for charter but generally on case by case basis ,
fishing onboard Black Watch 40 , for this you budget for US$. 1000.- per day and by appoinment only .
