Many good responses but the majority say get a motor.
From a retired sailboat dealer familiar with the O'Day regardless of how well versed and/or experienced, you are at a disadvantage with the winds constantly blowing toward the ramp with docks, boats, rocks, shallow area and so forth. Even those with skills, there is one major disadvantage. What about that sudden gust of wind which you have no control over. I recall an O'Day with the same circumstances and a very respected and experienced sailor. He heeded my advice to keep his insurance up but found that sudden gusts damaging other boats and his as well was not his cup of tea. He purchased a motor. He also was injured too once. For the safety or your crew as well as yourself, I suggest biting the bullet and buying a motor.
