How small? Before we give advice I think it would be handy to know what craft you have.
I have a 15ft Terhi and have fished south of the needles many times. Fished 10miles out and done a few trips with a 20+ mile return journey.
Judge your craft suitability on your experience & confidence. And importantly weather conditions & more importantly, the forecast! No point going out in perfect conditions if it is going to change half way though your day!
Stay safe!
