I woke up early and tried to make it to Akaiami, which is about 4 miles (one way) from Samade's bar where I rented the Kayak. I was pretty tired after about 3.5 miles and figured it'd be wise to save some energy for getting home.
I did make it to the motu before Akaiami and had lunch in one of the most beautiful places I've ever been.
On the way back I almost got stuck in a squall. On a kayak. :) Kind of scary.
