Mcjenson - I have only had her up to 67 thus far. A lot more in her so I know it will get into 70's. I need a calm day on the lake. I don't trust the Potomac river as it is often rough and there can be a lot of subsurface junk after it rains hard. Had a friend who did $25K damage to his penta pods on his 44 ft Galleon last year hitting a log. I'll post speed updates when I can.
