Is Kiteboat a company that sells... kite.. boats?
Or is it a technology?
Why is on HN?
Is a kiteboat a boat that's sailed by kite? or is it just a cute name?
Are you selling something or just showing off your cool boats?
What's the goal?
Why am I looking at your site?
Who are you?
What's the Log In link for?
What would I be logging in to do?
I get none of that from the main page, and none of the links in Navigate look anything like "About" or "FAQ" or "Who We Are" or "What is Kiteboat?". All I see are videos (which I rarely watch for various reasons, but even so, few look like they explain what the Kiteboat Project is), News (why should I care if I don't know what Kiteboat is?), Advantages (compared to what?), Tests (???)..
I wound up clicking around and got answers to some of those questions, but for someone who just lands on your homepage, that's a lot of work to expect them to do. Ideally, you would have something front and center that says "Kiteboat: A Better Way to Sail" and then a button that says "Find Out More" or something. Because otherwise I'm either just gonna navigate away, or start clicking random links til I find something that explains WTF I'm looking at.
