Stepped hull?

We are using a 20 in leg and Sport Master bottom unit with a 1.62:1 drive. We decided against going for a stepped hull for two reasons: ride and fuel tank capacity. Although there is meant to be a circa 5% speed gain from the step, I felt that a smooth ride might be more important for the Round Britain Race and we also have a 450 litre tank under the floor which I think would have been harder to do with the lower volume stepped hull. I did go for a ride in Graham Jelley's stepped hull 8.5 though and it was very impressive.

Is the stepped hull a harder ride?

I thought it was the same hull with steps added via a plant in the original mould?

As Dolly Parton said ' if you want the Rainbow you gotta put up with a little rain'

good luck they are one of the better boats so make sure you beat some hardboats in the race

Stepped hull or not?

John, you are right (I think) on how they made the moulds to incorporate the changes made by Lorne Campbell. As for the ride I have to rely on the people who have much more knowledge than me such as Graham Jelley at Scorpion who has a great deal experience with both types.

We have the other stepped hull 8.5 with twin 175's (for sale by the way!). You have, IMHO, got the best set up for the race as a stepped hull is not something you would want to go round on.

The best way i find of describing the hull in compression to the normal hull is "flighty". The step's do make a big difference but you have to be much more on the ball driving it compared to the normal hull. Which given how long the race will be is not a good idea.

Has your new type console got the electric motor to open/close it?

Regards
Stuart

Steps and console

Stuart, thanks for your feedback on the stepped hull. My feeling so far is about how steady the 8.5 seems when compared with my 7.5.
Graham said he wasn't happy with the way the motor worked on his hatch so we went with the manual approach which is fine. It saved me 80 and weighs less. We are now having a leash fitted so if someone doesn't do the catch up properly it shouldn't cause too much damage.

Heading West

Cookee, assuming half reasonable weather we will be having a run from the Solent to Plymouth on Saturday lunchtime this weekend. We will return on Sunday morning. Would be good to meet up if you are around on either Saturday pm or Sunday morning in Salcombe.
