Bubble: The P30 should handle those conditions with aplomb. Practically what it was designed for.
You likely will need a decent-sized headsail for forward drive, esp. given the famous Bay chop. You could probably forereach under reefed main only, but you aren't going to make many miles toward home that way.
Yes, the 130 headsail is probably too large for those conditions, and probably (given where you sail) it is cut fairly deep as well. But since you aren't made of money, don't have unlimited space below for headsail inventory, and lack roller furling, there are some things you can do to make that 130 work for you in heavier conditions.
First, is your backstay on hard? a genoa that sags off will have deeper draft and a poor attack angle when pointing. Likewise halyard tension: needs to be taut, taut, taut, or the sail will scallop and pull your bow off the wind. You can also add a foot reef to a genoa (really!), or a simple cunningham to the tack that will pull out some of the draft and move the rest forward.
Second, you can depower your genny and lower its effective center of effort with twist. As ZZ4gta says, try to move those jib cars back until the upper half of the leech is spilling much of its wind. You don't want it fluttering too much -- just a wide open slot and upper jib telltales pointing upward. Cracking the sheets may help, too, but that can lead to leech flutter and degrade pointing ability. Might snug the jib leechline, if it starts motorboating too much.
We don't have a traveler on our little SJ21 & have trouble controlling mainsail twist. Flat-as-a-board reefing certainly depowers the sail and keeps the boat under control, but we've found the boat loses way as chop increases. Could you maybe pull the traveler slightly to center and ease the mainsheet a couple inches, to increase twist? We've found it helpful to slack the clew reefing line a titch, which does much the same thing. Trim is different for chop than for flat water or long-period swells.
Finally, I think you did great. If you never learn to sail your boat when it gets a little stinky ... whatchoo gonna do on a lee shore when the engine decides to quit? It's a sailboat
. It likes wind
. We've learned (the hard way) to handle our 1500# San Juan in winds over 45kts. It's gripping, it beats you up, and the boat has to be coaxed along ... but given our auxilliary is a trolling motor, we don't have much choice. Better to figure out how to sail in rough conditions now
, on your terms, than being forced to learn under genuine duress.
