Where do I start?

I used to live in Milford and cut my angling teeth as a kid catching
Gobies from the end of the pier at Hakin Point - small world ;-)

Again, since its the summer *allegedly* I'd say go for Mackerel. The
minimum you need from a boat is a handline with a set of feathers and a
weight. Drop the feathers over the side, let them sink a bit and then
jig them up and down. If you have a boat rod and reel it will be
easier on the hands than the handline option.

If you get bored of Mackerel fishing try using a baited hook fished on
the bottom - Ragworm or Mackerel strip are good for this.

As someone posted earlier it's worth popping into your local tackle
shop as they will not only be able to help you with bait and tackle -
but may also give you some tips on where to fish.

The great thing with sea fishing ( boat and shore ) is that there is no
right or wrong way to do it. For me a lot of the enjoyment is just
trying things out to see if they work.
