I've been wondering, but now I think I get it.
Three sites out of the top ten are yours.

And you're worried that someone will come by and point this out to Google, making either or all removed from the SERPs, even though you have done absolutely nothing to deserve that?

...

If you think about it, that'd be a manual penalty for same ownership. Now imagine that Google would penalize websites because they are owned by the same entity. Let's say a major company that has a website for all its related fields and aspects.

They won't do that.

Not only because the sites cover different aspects, for different purposes, are not SEOing each other to the top, and even if owned by the same entity, carry out different missions entirely, but because...

No one will care.

The competition reporting you?
You can't even contact Google with having found bordeline SPAM, do you think they'd respond to such requests?

"Dear G00. I just found out that my competition owns more than a single website on the same topic, albeit of different aspects, I find this to be unfair. I'd like them to be removed from the SERPs for 'speed boats' if possible. Kind regards."

"Dear competitor, thank you for your notice. We have removed two of the websites of this entity to provide fair use of the internet, even though to our knowledge and best of our efforts, these were providing people with just what they need to cover those aspects, and didn't even make use of one anothers' popularity in an unfair way. Divide and conquer."

I'm not sure this would hold up to any of Google's past, present and to be policies.

...

Besides, I see entire networks of same ownership, same topic, different aspect sites linked together whatever I type in. In sectors so competitive they're known to be hand checked every now and then. And those sites are interlinked. Yours aren't.
