Keep in mind that I have yet to build a Greenland boat. That being said, having built a baidarka, I think they're excellent craft. Sturdy, tons of room for gear and all, and visually very interesting. They're very fast (low wetted surface, controlling for length/beam ratio), and never fail to start a discussion on a ferry or harbor parking lot.

Disadvantages vs. Greenland boats - Aleut boats have a much higher parts count, and are correspondingly more difficult and time consuming to build. Also, I don't like the horizontal coaming - the high back makes rolling more difficult, and entry *MUCH* more difficult (wet exit and re-entry really isn't an option with my boat...). Much has been said of the handling benefits of a hard chine, particularly in rough water - I haven't paddled a greenland boat, but my Chesepeake IS hard-chined, and doesn't really provide that much of an advantage (that I can tell). Finally, though the bow and stern are fascinating details, I actually like the look of a Greenland boat in the water better than the baidarka - the Aleut craft has a straight sheer and deck ridge, and looks like a floating cigar. (With an interesting nose, though...) I love the swoop of the Greenland boats, particularly if not overdone.

All in all, if you're planning on camping a lot, I'd lean towards the Aleut boat. Otherwise, the decision comes back to asthetics, and the issues I listed above.

Good luck.
