I hate to be a nay sayer and I don't intend for this to be mean or judgemental -- I hope you can take this as constructive, yet firm advice.  Your last two trips showed that you are not experienced enough to do the R2AK trip.  You were literally scared for your life in moderately severe conditions within immediate rescue range.  The R2AK is the opposite of that.  You had very near disaster moments due to poor judgement and lack of seamanship that could result in your death on the R2AK. 

Remember that you may be 1-2 days away from rescue when you press your PLB button, if you can get your frozen hands to work.  When you are malnourished and severely dehydrated, you won't have the sense to push the button because your brain will be starved.  When you're not dressed properly and your crack reappears, your survivability in those waters will be measured in hours, not the days it will take to find you and rescue you.

As evidenced in this thread so far, though, you will not heed this advice and you will do this trip anyway.  So, before all else, make sure your family is whole and update your life insurance policy for current needs and costs so that your poor decisions don't financially burden them. 

Just my 2 cents.

I think I've observed what most folks here use, and have noticed trends in how they tend to use their kayaks. What am I missing here? What are the main reasons y'all chose one kayak over another, and what are your primary fishing techniques?
