I got the Alsek a month ago. It is my 4th kayak, 2nd one this year. I paddle alone so I wanted something I feel very safe with and the Alsek meeets that requirement. It has a bit of speed, tracks quite well even without skeg, and has lots of room for me and whatever I take on 2-5 hour day trips. I took it out on a very windy day and was very pleased with the skeg.
Biggest problem is comfort with the seat. I'm working on fitting it out specially for me, but I need a good seat pad to see me through several hours of paddling. Other than that, it seems to be a good fit for me.
It's weight doesn't bother me since I bought a trailer and the Alsek stays on there all the time. I just hook it up the Jeep and take off. Much easier than cartopping. Necky appears to have discontinued the Alsek. It isn't in the 2000 catalog. I think, perhaps, the Zoar Sport replaced it. Too bad, because I think it's a great boat.
