Without at least a depth finder it is hard to be sure. However, by steering a compass course and using a time/speed/distance calculations you can get close. You have to know how fast you are cruising, and how far you have to go. Then with those 2 numbers TSD calculations will show you how much time you will have to sail to your destination. If you can still see land you can take bearings off of known objects to fix your position and get over that spot you want to be over in the ocean. Without any other tools it would be impossible to do better then that.

By dead reckoning, using a compass, points on shore, chart, speed you can find your place on the chart. You do need an accurate clock, and speed. You can take bearings on 2 objects ashore and see where their lines cross. Hopefully underwater hazards will be charted.

I'd say that is enough and you probably have to know how to read them, it sounds like fun though, I don't think I have ever been out on an ocean.
