Check list....don't leave home without....
Paddle leash (any long piece of cord that has a loop on one end and is fastened to you or the yak on the other.) If you drop your paddle, you may be "Up S#$%$creek without a paddle"
Life Jacket ( you know that)
When dismounting for the first time, you will find it easier to get off in one/two feet of water, rather than nearly on the sandy shore.
A long piece of rope tied onto the bow to hold the yak while you stumble around getting on or off.
Have fun! richg99
