This is Dan and Kika, sailing on UMA a sailing boat they bought for 3000 USD, and did a total refit by themselves.
And they are sailing!

Sailing UMA

They have a You Tube channel where they post videos about their life sailing, about the refit, about all these ideas they have to make their sailing boat better, like an electrical engine, alcohol cooking table rather than propane one...
It is also about how do they finance their lifestyle.
They are very interesting, adorable, and super smart!
