Devotti Single Hander

Actually, all masts, even with shrouds, bend... The problem is the way they bend!

The D-One has a mast mutuated (but not the same) from the Finn, with a winged profile and with an external mainsail halyard (this help mantaining the mast completely sealed to prevent complete inversion during capsizing). Upwind, it works like a Finn mast, with a nice bend afterward that helps the sail to depower:



Downwind, here came the complications...

The pulling force from the genny can cause the mast to bend forward and leeward, powering the main and causing at the extreme the mast to break. You can prevent this in two ways: putting shrouds on the mast or making the mast very stiff. In the first case you can make the mast softer and bendier, so you can control it with few tweaks; in the second you have to play with precise positioning of the halyards exits (that's why the final production D-One sports an higher genny head point and different profile for the asymmetric ) and with gadgets like vang, cunningham and traveller. Then more speed you achieve, more your apparent wind will shift toward bow and your mast will suffer less pressure.

Whoops Doug,

I should have mentioned that the boat that Sten is sailing has an older development mast which is much softer than the production mast.

I notice they have changed the design of the wings a bit which does improve the aesthetics.

It will be interesting to see how it sells internationally against the RS100. The RS700 (LDC) is theoretically quicker and easier to sail than the MPS (Devoti) but the MPS holds its value better and seems to be the "trapeze SH of choice". Is this because the 700 is seen as a UK Class while the MPS is international? Will history repeat itself?

I get my info from the difference in PY numbers. If you are associated with the D-One marketing team you're are not doing them any favours. You may have missed my point. In fact, thinking about it, I merely asked a question. Didn't sl*g the D-One or the MPS. I'm not a specialised critic (I have the occasional ironic pop at GRF and have a pathological hatred of any dinghy with a blue sail with an E on it - but that's it) and I haven't seen any pimps in the mirro since puberty.

ciao
