Qaannamik pinnguaatit (kayak games) by H.C. Petersen
This small book is available only in Greenlandic but includes an excellent pattern for a tuilik and a diagram for three different blunt-tipped "practice" harpoons. The book opens with a drawing of a mother moving the arms of her baby to begin his kayak training and a balance board used to hone his balance. Also includes a short bit of information on sculling, rolling, and the rope gymnastics.
