On the other hand I-17 board are huge compared to taipans. Thruth might be somewhere in the middle. And bear in mind that Board of I-17 were designed for the I-18 and copied to the I-17 to save costs. I-17 board at 70 % length which still is about 0,7 mtr. which is more than Taipan full down. BTW I'm not saying that Taipan board aren't at their optimimum, I just look at A-cats (Auscats ?) and some other optimized boats like Stealth and see that Taipan went a totally different direction and wonder which of the two is best.

<br>I can imagine that rather high aspect (which is not always the same as long !!! ) is better but that I-17 had to much total area for the boat and that Taipan's ratio area to aspect ration is better. Maybe Auscat ratio is even better still. ?
