No personal knowledge of the P27. But in looking at the brochure on the Pearsoninfo.net it looks like the jib and mainsheets are well forward of the helm, making it a pain to singlehand this boat.
I have a P35 that I singlehand quite frequently. My jib sheet wenches are on either side of the helm and my mainsheet is behind the helm giving me easy access to all my sheets without having to move from the wheel to tack or make adjustments. Also, if you're going to singlehand a lot an autopilot is a huge help, especially in raising and lowering the sails. Same for furling jib.
