This sounds very familiar as i recent set myself up for offshore after years on the inside lol. You will absolutely need an EPIRB, safety equipment, VHF and a PFD. I have an old Lazeabout with a 70 and it has never taken more than 20min to get there at around 18-20 knots. Yes thats fast but if you cant do that speed i really shouldnt be out. Always picks up on the way home but keep an eye on the weather and take it slowly and adjust to conditions. In all honesty if you have years of experience you will know what is safe and capable for your boat just keep an eye on the weather, never trust a report. As for longy its not the magic fishing spot i thought it was lol. Had much better luck at the FAD, arty, Annie, heads etc.
Enjoy and stay safe!
