Wouter,
<br>
<br>Thanks for answering that quickly, I agree with your answers, except one point, the weight issue.
<br>
<br>First Your calculation of a extra light Taipan, I think it’s quite a bit too enthusiastic calculated, let’s go to the details:
<br>
<br>Carbon mast -4 kg: Then you have a real light carbon mast, but ok.
<br>
<br>Carbon Rudderstock/rudder/boards -5kg: I don’t think you can get this reduction.
<br>I don’t have the message anymore from Phil, I hope I remember it well
<br> I once read the article about the paper tiger carbon boards, very nice indeed, but the difference is not that big.
<br>The boards had a smaller section as for a taipan; as I calculate it for the same section as a taipan, the reduction would be about 15%;
<br>Please correct me if I’m wrong at this, Phil will know it for sure.
<br>
<br>My boards are 1.9 and 2kg; so that gives a reduction of 0.5kg total.
<br>For the rudders/stocks: they also are already light at 5kg total, but let’s say You can get 1.5 kg reduction with carbon
<br>
<br>Spi pole + Boom –2kg:
<br>My Boom=1.44kg, Suppose in carbon it’s 70% of it’s weigh, and you get a reduction from 0,432kg.
<br>Pole: 70% of 2.5kg gives 0.75 kg
<br>
<br>Dynema trapeze/pole wires –2kg:
<br>My total shrouds, including trapezes wires are just 2.5 kg! So I don’t think you can get more than 0.5 kg.
<br>
<br>This gives a total reduction of about 7.5 kg,
<br>This means 111-7.5=103.5 kg.
<br>
<br>So still 3.5 kg’s overweight.
<br>
<br>That’s just my Taipan, I think we also have to ask John Pierce (Stealth), as designer maybe he can tell if a stealth for example could be brought at 100kg, including spi. (=15kg reduction, and the stealth has already a carbon mast.
<br>I suppose it will be very hard to achieve this.
<br>
<br>If this is true, 2 boats are already obsolete, at least the stealth, and for the taipan you’ll have to invest quite a bit..
<br>
<br>I’d also like to hear John’s opinion, for me I think 100kg, excluding spi or 105 kg with spi would be the absolute minimum.
<br>
<br>Keep on the good work,
<br>
