Thank you for all of the great advice! I would like to check out the Revo 11, however, I drive a Subaru Imprezza and I'm wondering how expensive and hard it would be to have a roof rack installed? Also, how heavy is the Revo 11? This is one of the main reasons I've been considering an inflatable.
Subaru's are known to the "active lifestyle" crowd. Depending on the year of your Imprezza, if it doesn't have a roof rack (which it sounds like it doesn't) It will have pre installed threaded holes usually behind small black plastic covers, in the black rubbery strip that runs the length of the roof, just above the doors. Those threaded holes are built for roof racks to screw into.
The installed roof rack would look like this:
Subaru sells roof racks at the dealer, but there are also Yakima, and Thule roof racks that make custom fitted roof racks to screw into those holes, and also match the profile of your roofline.
Don't be afraid to check out a craigslist for used roof racks. As I mentioned, Subaru's are very popular to people who like to Bike, and kayak etc.
As far as lifting the boat. As I said, it's not the weight, but the technique. You can often get away with only lifting half of the boat onto the car at a time. The Hobie dealer should know about how to help you load it.
Here is a link to all of the specs for the Revolution 11.http://www.hobiecat.com/kayaks/mirage/revolution-11/
Keep in mind that although the boat weighs 70 lbs, all in. That weight includes the seat, paddle, mirage drive, water bottles, etc. So you're probably closer to 60 lbs.
Plenty of 150 lb men lift 100 lb longer boats onto trucks on this forum, with proper technique, and maybe an accessory or two on the roof rack, a 120 lb woman could lift the Revolution onto an Imprezza.
But again. If you're not comfortable with it, the inflatables are made for exactly that reason. See if you can try both of the boats out. You may like one better on the water, but end up with the one that you'll be able to get to the water.
If you can't get it to the water, you won't use it.
