G/day Young fella,
All the above advice is very good.
If you have not got a manual for your sounder,you can download
them free on line.PDF format.
Your boat is good enough in good weather,but experience is essential
otherwise panic sets in if you get into trouble.
Even on a good day just outside you will roll and pitch like mad,
while you are near a headland it is rough,move out 1/2 a click and it
smooths down.
The best way to learn is in another boat and watch the skipper,
fishing is on its own,but that sea can be a killer at any moment.
take all the precautions don't venture out in bad weather,learn your sounder
and you will have a ball.There is no thrill better than pulling in a PB.
Good luck and enjoy your fishing,you can learn a lot listening to the
guys on Here.
Cheers Rick.
