David, I am running the Raker HO, 24 inch pitch. About the only difference between the HO and the standard Raker is that the vents are adjustable. I have them just cracked open to help with planing off. I was told that closing them is better for top end. Not sure if that is true or not. I have not done any speed runs since I acheived the 71.4 gps. I guess I am just happy with that.
Jason, there is a dam at each of the 5 locks on the waterway. They are used to manage the lake Okeechobee, Caloosahatchee river, and St. Lucie river levels. Interesting fact is that during drought periods the locks go from on demand openings to hourly openings or even as low as 3 times a day openings.
