If I may, its not just about the size of your boat but rather also the deadrise/angle or how deep the V is and how suitable your boat design is for ocean conditions. That 16ft lifetimer is a well built aluminum boat built in Duncan and designed for ocean conditions.
I had a 16ft double eagle that could handle some bad weather if I went slow but had a deep V hull designed for ocean conditions. I've been on a larger boat that had a shallow hull and open bow rider. It was ok for flat calm days but a bit of waves and it was NOT ideal.
Suggestion if you are new is to try taking it to cates park first (protected in indian arm) and try to go out and run your gear and boat in relative safety of the inlet.
1) Wear a life jacket ALWAYS. ALWAYS while on the water
2) Have a waterproof, floating marine VHF clipped to your life jacket (that you are always wearing)
3) Know where you are in terms of location so that if you need to call for help on VHF 16 you can give them a rough idea of where you are/what you have one etc.
This is coming from me from a perspective of not just being a boater but also a mariner and someone who has had to participate in some search and rescues.
I know I sound like a nagging old man but I honestly just want people to be safe and come home to their loved ones. No need to have a tragedy on the water if one can be prevented.
All the fishing stuff I'll leave to others.... as they like to say in my profession "safety first"
