Particularities of Ontong Java's catamaran (?) of Hans Klaar

Hello. Ontong Java certainly is no a Wharram, but, James Wharram expressly welcome him and is friendly with the design, etc.

My question is if anyone knows why the hulls have different length?

And moreover, if such circumstance benefits in any manner the sailing ability.

I also see that the mast and the foresail are placed not in the middle but more close the the longer hull.

Thanks.

I seem to remember that Hans wrote quite a bit about the rationale for his design: https://www.atomvoyages.com/articles/sailor-interviews/327-hans-kla...

Thank you Michael. I understand he followed some ancient pirogues. I knew this article, but didn't find therein a specific explanation about the sailing performance, Tks Rds

Hans Klaar started off with a Wharram boat but later on moved on to "his own" designs ... Plse check;

Thanks for the Vimeo link, much enjoyed it. If I were a bit younger I'd build one like that.

My boat is currently "locked-down" in the boatyard due to coronavirus. (UK). After a lousy wet winter, when working outside was impossible, now the weather has improved, we can't get to our boats. So it's nice to look at videos of them sailing...
