aye first off get a big boat and stock it with tons of ale
Second float out till you cant see any land at all..
third drink some ale
fourth just start fishing...BUT I believe you have to be 65 fishing skill to get a small chance at it...cant remember for sure...
fifth drink more ale...For catching the big fish is fun it does land at your feet. Just dont do the mistake of cutting it up for bait...
Just keep casting too....There are I have a book of the times I have caught the big ones...Mostly for me it was 2 a day...
I have tried fishing while moving and fishing while standing still....Both have equal chances...But moving does help to get away from ALOt of sea monsters
good luck and keep us updated...btw does anyone remember who has the biggest fish ever? I remember back about a year or two ago someone broke the old ole record.
