Re: speed loss with bimini
I have an aluminum v hull but mine runs faster with my top up, it is the only time it has ever done 31 and I was running into the wind so it actually acted like a wing, I was watching the supports to make sure it wasn't going to become a kite, normal speed is between 26-28 gps.
There are alot of variable to this but I would say on average it isn't enough to worry about,2-3 mph isn't really that much and if you want to run fast for a distance just drop the top but with the flat rails in front you are essentially pushing a barn door through the wind so the top isn't going to make that much difference.
