Narrative:

I was doing a right crosswind departure from oar. I was watching for traffic and planning my return to pao. This was my first time into marina and I hadn't been over the santa cruz mountains in quite some time. The inbound to oar kind of intimidated me because of the mountains, and I wanted to be sure to get to 4500 ft (west course altitude) well before the mountains. Simply put, it didn't seem the aircraft could climb past 3600 ft in that space of time. Once I noticed it, I was out of class C airspace but I knew I had to have been over the published 1500 ft floor at some point inside the airspace. I was monitoring monterey approach. There was no traffic in the area and I did not receive a call from control.
