Well Robert, I happen to have a kayak that I believe would fit a person of your size. The maker says they are built for people up to 6'-8" tall. No, I don't want to sell mine. It is a Novus Composites Expedition and is 19'-2" long.
You mentioned that you were thinking about flying to Seattle to look at kayaks. That would put you in the right area, because Novus Composites (NC Kayaks) is located in Tacoma, Washington. They only sell factory direct and their prices are very competitive because of that. You can go to nckayaks.com and get some idea about what they have to offer, but what you can't see is the craftsmanship and extreme grace of these great boats. You have to see and touch these beauties to believe it.
At the present time, they are having a 25% off sale on any ordered boat. That should mean that the price of an Expedition would start somewhere around $2250 in the standard layup. The lighter weight layup should start at about $2474. Mine is the Lt. model and I think it is worth the extra bucks.
At least I would urge you to check them out on the internet. The Expedition isn't the only boat they build.
If you have any further questions about the boat, I'm more than happy to answer either on this forum, or by private message. The guys at NC are great to talk to by phone, or via e-mail.
One final thing to keep in mind if you happen to have an interest in an NC--the seat is stationary, but when the boat is built, the seat can be located 1" further back than the standard position. I highly recommend that.
