The wild card is the Blaze which I do fancy even though I'm a bit light but does it overlap the Spice a bit much?
Of course it does .... Er ... hardly a fag paper between them come to think of it.  |

Returning to the topic, I've just spoken to White Formula re Spice hull weight and the quoted 85kg is bare hull moulding only. Added to that are a couple of space frames and a full fit out and you're probably up to 100kg without the rig and foils so mine's not looking too bad after all (but not the super light baby I'd hope for......).

I'm hoping a trial sail will tell me if I'm in the ball park. I nearly bought a Laser a couple of years ago and a trial sail reminded me why I sold the last one and took up windsurfing..... If the Europe boom is simply too low for my ageing back I'll know pretty quickly, likewise if the Aero is a flighty beast then that's not for me either.
I bought my Spice nine years ago based on advice and a gut feeling and have loved every minute of it (still do) so I do have some parameters for the second boat. I will be a unarig singlehander, no trapeze and such that a 75kg sailor is at the top end of the weight range. FRP (not wood) and no heavier than a L@ser to manhandle on shore, decent controllable rig (no soft, sleeve luff sails, I grew out of them in my Div 1 days). Carbon sticks would be nice but not essential and I have a leaning towards unstayed but that's not set in stone. And moderately forgiving to sail (which rules out RS300 for example), particularly in a blow, I'm good in light airs so something I can get round in when it's windy would be nice. I reckon that leaves me with :- Europe, Aero/D-Zero, Lightning 368 and Solution. I'm nearer the bottom of the weight range for the Supernova and all the used Streakers I've seen are wood so they're out. The wild card is the Blaze which I do fancy even though I'm a bit light but does it overlap the Spice a bit much? Lots of good advice anyway, thanks all.

Although trying a design before you buy it is obviously good advice I'm not sure I really subscribe to the idea.
We live in an age were buying and selling something dinghys is comparatively easy and you never get to really know a boat until you live with it.
If Id tried my canoe or Musto before I bought them I would have just thought they were hard work and would thus have missed out on some great sailing, sailing that you can only experience after having spent some time in the boat. |

The Aero is epoxy - the D-0 is I think vinyl-ester, the Laser polyester (I'm sure to be corrected if wrong here !) . The lay-ups vary enormously and so on. The laser has alloy spars the other two 'carbon' .... Very difficult to compare and not necessarily appropriate to do so but on PY paper the handicaps must, in part, reflect these amongst many other factors - as they do. I race against all three regularly and the relative speeds experienced appear to be ... well I'd say the Aero 9 is generally the faster, pretty closely followed by the D-0 with the Laser a fair way behind.
'Durability' is very far from related to just weight of lay-up, resin system employed and so on... there are many papers and books on the subject ... and boring indeed they tend to be. ;-) Best to put down the keyboard really and simply try all you can .. Edited by Cirrus - 14 Sep 16 at 3:20pm |

He could probably fill it with helium and have it levitate without foils
 the next big thing maybe?

I imagine that there is not much diff in surface area between aero and zero. Zero a tad longer I guess.
Zero has 300gsm laminate as designed, aero 200gsm, which accounts for the difference, which I am lead to believe is around 8kg. And I concur with Sam spoons that a thicker laminate dramatically enhances robustness. 200gsm is fine globally you will just have to look after it 50% more carefully :-). Saw something from moth nationals alister richardsons home build is 80gsm (carbon) over nomex now that is brave!!! |

As far as I am aware the Aero is laid up using an infusion technique (I could be wrong). the D-Zero is more of a traditional layup. In terms of overall surface area I would say there is very little to choose between them.

Total surface area is what counts for weight though. There's a hell of a lot more material in a DZero |
