Just another option for trying out some of the lightest (and most compact storage) boats in the world, whether you want to rent or try before you buy. Seems expensive, but five friends might be able to kick in and bring the cost down, if they are willing to try things out, one at a time. I am not necessarily endorsing this company, as I have not tried them out, nor do I have any connection with the ownership.
