Trying to make sense of the DF65 B and C rig rig

I remember at a Poole weekend where I had got a set up where the boat was so fast but stupidly I did not measure the settings. Last weekend I had no edge over anybody so I am trying on this page to unravel any differences. Small margins on the DF65 make a huge difference


I had a look at a series of photos to try and understand the difference between my rig 54 and Craig's 121.

In summary I think he was able to point a little higher all weekend, carried more mast rake, set a slightly softer jib leech, sheeted it further out and kept the main boom more central.

I tended to sheet a tighter jib with a twistier main so I was confident I would come out of tacks more easily but obviously this was slower. The boat was nicely balanced but did tend to sail lower than other boats upwind

When I look at the mast step, I note I was a notch forward of the aft position so that would account for the lack of mast mast rake. Schoolboy error.






Craigs setup looks perfect here. Main and jib twist is parallel. Jib boom looks to be sheeted on the edge of the deck and the main boom near the centre, maybe a centremetre of the centre

A rare occasion when I was ahead of both John and Craig but both have the main boom slightly more central than me. It is hard to compare jibs in this photo.

I think in this phot Craig is carrying more mast rake as his boom looks distinctly lower but it could be a trick of the camera

You can just see how far out Craigs Jib boom end is

From this photo you can see Craig has more twist in the jib which will allow him to point higher

I show this because it is nice to see I get the occasional start right

If you look closely you can see Craig's jib is more twisted and his main sheeted more centrally with slightly more twist. This keeps the slot wider at the bottom and would enable him to point when needed. More twist is definitely good in the wave we had at Bartons Point

This photo clearly shows the amount of twist

Looks like he is in high mode here with the main boom in the centre and Jib boom inside the deck.


This picture clearly shows my error in setup. Not enough twist in the jib and too much in the main and main boom could be more centred.

Such a well balanced setup


So what are the fixes


Main sheet closer to the centre

Jib sheeted on the outside of the deck with more twist

Make sure the mast step is rammed all the way back.


I will have to wait until the next TT in July to see how this works.


My thanks to Dave Budden and Simon Thornton for the great Photos
