I have a made to measure boom tent for a westerly nimrod. As far as i can see it has never been used but has marks from dry storage only. It is a fully enclosed tent made from heavy duty blue cotton canvass and a lightweight aluminium frame which sits on the boat.
It has good zips and theres a door/ window for access on one side.
We are located in Darlington, however i make regular trips to the lake district so could deliver anywhere along the A66 corridor .
