Speed Rails

JF - you mentioned them, someone else as well...

WTF are speed rails, how do they work? Will they work on a bladerunner? Where do you get them?

Any info...

Mannerfelt do some aluminium ones that you screw on, and we laminate them on - have a look at our boat in Pwhelli ...

They basically give more lift by letting less water escape sideways from the centre of the boat - it does give a slightly harder ride as well.

They might - to be honest thee is a bit more to it than that ............. it depends where on the hull you fit them and how the boat is balanced to start with. If you use bow lifting props to get the speed up, then putting them right at the back on the inside spray rails would be the best place for them, or if you use stern lifting props like a bat boat further forwards would have more effect. I would say it would be the last thing after getting the best out of a boat with props, balancing a boat etc (sticking things to the bottom of the boat is a bit of a job!) - however I'm sure someone will have a different view!

Don't forget if it's still a leisure boat that it will make the ride harder, make it harder work to drive in the rough (too much lift and the boat will "fly" more), and they get in the way getting on and off the trailer. Oh yeah and if we fit them it's expensive!
