[Welcome to Knitting Help!
When you've bound off the 2sts in row 1, you're going to work only one side of the deck. On row 2 you'll knit to the bound off sts and then turn just before the bind off. Don't knit across the bound off sts.
After row 4, cut the yarn leaving about a 6 inch tail to weave in later. Attach the new end of yarn to the other side of the bound off sts so that you can now work the other side of the deck.
(14 sts as base)
R1: K6, BO2, knit to end
R2: K6, turn
R3: BO1, knit to end, turn
R4: K5, CO1, turn
R5: K6, turn
R6: K4, k2tog
R7: CO1 and knit the cast st, K5
R8: K6, CO2, K6
When you knit row 8, you'll be joining the two sides of the deck (14sts) and completing the hole for tha mast.
This sounds like an adorable project. Please post a photo when you finish, if you'd like.
