Exactly, I did my first ever Time Trial the other day.  My top speed was well above the Moth record and average was above 20knotts.  Hardly breath taking quick.  But relative i guess.

Presumably D-0 is easier than a Laser in one aspect that every Laser first-timer notices:  the sheet not catching around the transom if left unattended on tacks & gybes.

Given the consistent reports of light sheet loads, however, I am wondering why the opportunity hasn't been taken to move the bridle further forward.  Sheet loads would presumably still be acceptable, and yet the bridle system would allow the boom to be pinned down over a greater range of sheeting angles.  

This is something that could usefully have been done on the Laser from the outset; as it is, once overpowered you have to rely on the kicker to hold the boom down when moving the boom further off the centreline.  It would also have reduced sheet-snagging on that boat.  Oddly, the Laser 2 does have the bridle mounted away from the end of the boom, although there you are more concerned with centralizing the boom.

Hi.
The bridle goes pretty much full beam of the boat i.e 1.4m, rather than the laser which if memory serves goes out to 1m or so, giving a sheeting angle of only 9 deg, which is too close for windy stuff.
I could get 14 deg on the punk just on main and trav, I think you can still get out to pretty much 13 deg on the D zero without using vang - all helped by a slightly shorter foot length than the laser. Moving the bridle forward would mean having to use fittings and mechanical fastners  to anchor the bridle in an area where you might want to sit, or moving the slope of the transom forward thus losing trimming moment for windy reaches. The traveller going through drilled holes through the hull/deck join at the transom was also necessary for the original punk under floor sheeting.
The low sheet loads despite about 32kg leech tension when block to block have suprised me too but are testament to using 40mm harken T2 ball bearing blocks, and having much less blocks and corners to turn than the orig punk system.

Seems that way ... Devoti certainly know how to design and test rather than rush to market ...

I don't think the D-0 is made out of the normal industry norms (wood, epoxy, GRP, carbon etc.), so how - to repair dings and - god - forbid holes? There is no access to the inside of the boat is there?
Like some other things - sailing is more enjoyable when you do it with someone else

Unobtanium from the planet.........

It doesn't say on the site, FRP or perhaps epoxy. The D-One doesn't have any hatches either, but don't think thats ever been of concern. Modern boats when built well are pretty tough. You just need a bung. If water comes out, its your fittings, if it doesn't its dry!

Obviously if you start running into things you shouldn't be sailing anyway Embarrassed

The big deal breaker of no hatch is no hatch bag for the mars bars Angry

As i understand it its made the same as most other dinghies.  If you hole it then it would have to be repaired the same way as every other boat.
