Weston Winter Series

The first day of the winter series dawned to a crisp morning with a severe lack of wind. So much so that Noycey decided to cancel his crew and leave his faithful steed keeping warm in the garage but made an appearance anyway. The more enthusiastic teams of Shiny Beast and Atum Bom rigged up and went for a drift.

There was only one race which finished Atom first and Shiny second but the race was a bit of a lottery with very patchy wind.

New Ellway 5 Design

Kevin Ellway has sent in a preview of a design he has been working on for Patrick Cunningham, which he though my be of interest.

Here is what he has to say about it:

The Ellway 5 design combines what I've learned from the SK4 design process, 4 years of sailing Beans (a Slug) with an 05 rig, and 32 years (yes really) of sailing cherubs into the design of an all round boat.

I have moved to slightly more rounded fore and mid sections than the SK4 due to the lower upwind speeds of the Cherub. The drag predictions are around 9-10% less than a P7 at speeds up to 8 kts. At planing speeds 10kts up, the drag is similar to a Slug, although drag predictions for non prismatic forms are a bit dubious using Stavitsky.

I will do an overlay with the slug, but basically the E5 is a lot finer in the bow and shoulder sections which reduces considerably the wave drag at high displacement/ semi planing speeds.

The design is still a lot more cherub like than the Bieker. This has a huge amount of chine rise throughout its entire length.

If anyone would like this design, it is free as long as the designer is acknowledged, but I would suggest paying the CCOAUK a donation of say £10.

I hope it is of interest.

Best regards

Kevin
