I thought it was a perfect day to be on the San Diego harbor. I have no small boat experience, much less speed boats. I am also in the senior citizen age and not as spry as I once was. I found it to be a great experience. I loved it, and as soon as it was over, I wondered why there isn't a sunset or sunrise experience. The guide was excellent and solicitous about our safety. Another regret is I went alone and talking photos while cruising the wakes was a bit hard. The boats at high speed go off the crest of a wave or wake then fall back into the water. I guess the nautical equivalent of a bump or airpocket. If you have back problems or find rollercoaster rides difficult, I would talk to the tour company before getting a ticket.
