Nicely done there that man.
I did contemplate doing similar and leaving the cover attached to the sib and inserting the pole when I want to use it.
Problem with my set up is I need to pull the draw strings positioned at the bow to tension the cover up properly .
The only way this can be done properly is from outside the sib so I should probably need to come ashore.
I think I might change the position of the main drawstrings from the centre of the bow to the rear of the cover so I can reach it from inside the Sib and pop the cover up whilst out on the water if conditions worsen.
Here's hoping I don't need it for this coming weekend tho
