We are buying 3 kayaks this spring. Both available at Canadian tire. The are the sun dolphin aruba 12 ss and the pelican alliance 136t for when our son goes with us.
they dont have skegs so they dont track in a straight line...and it adds to how much you have to paddle to keep them straight...they are very prone to tipping...I wouldnt buy them again.
I just got my 10 year old a sun dolphin Aruba SS 8 foot at Wal-Mart for 148 bucks. It is stable. He isn't the best at paddling so I have no idea if it tracks straight.
