Hi Sam, long time no see.
For general fishing you will need lug and Macky. They are getting Mackeral off Rhyl but im not sure if they are further out than you will go an a 5 hour.
The boats have started getting Smoothies and Bass and you may well fish for these at some point, so crab if you can get some and fresh lug for the Bass.
Its Steve Andrews boat who used to be in the club so the best thing you can do is give him a ring tomorrow to find out if he will be able to supply bait.
Here is a link to his website which ahould have some more info onhttp://www.supreme2.co.uk/
If general fishing, baited feathers work well, with lug or macky strip for Gurnards, Dabs, Whiting with the chance of Huss and Rays too.
3/0s on a 3 or 4 foot running ledger for the smuts or bass.
Have a good day and dont forget to post a report on here.
Hope to see you soon.
