with respect to being practical ?

well no not really but if your hot enough on spending money and effort to buy yourself a considerable advantage both upwind and downwind than, yes, there is nothing technical stopping you from putting one of these on your platform.

I mean people also disassemble and drive around glider with more than 25 mtr. oerall wingspan planes in enclosed trailors why chouldn't the same be done with the seperate panels of say a doubleslotted wingsail ?
