Re: 1979 Bayliner restoration. I need ideas and a gide in this project.
Looks good. It depends on how you intend to use it, and your budget. You'll likely want it to not be slippery, so whether it's painted, gelcoated, vinyl or carpet, you'd be seeking non-slip/non-skid.
Carpet may not be your friend if you intend to have fishhooks or blood and guts on the deck a lot.
For gelcoat or paint, you can add aggregate such as sand or crushed walnut shell or rubber compounds, or choose a coating that already provides this feature.
JasOutside used Behr Deckover on his boat, and seems pleased. It's affordable, designed to be used on heavy traffic areas, and fills minor imperfections. Read his thread for pictures and comments.
