Rubbaboo, did you use the Whetstone shelter as your primary sleeping shelter or as a separate shelter for cooking and hanging out in ?
On recent remote canoe camping trips I have been including a shelter in addition to the tent I sleep. I use it for cooking, eating and spending time when wind, rain or insect conditions dictate. I have taken one on both solo and group camping trips.
I started out using a tarp as my secondary shelter. Tarps can be configured for both wind and rain protection and are available with integrated screen mesh sides for insect protection.
I prefer the convenience and performance that freestanding or semi-freestanding shelters provide. I considered adding screen mesh to a Whetstone shelter but felt it may be too small for my requirements. This thread has me considering purchasing a Boat Solo Tent and adding screen mesh to it.
Your photo of the modified Whetstone shelter has motivated me.
