For my Mac 19, Margarita, I bought a Habitent cockpit cover. I used it for the first time last October in Scotland and it was a very useful addition. I have just had a weekend on Windermere - Chichester shake down - and I used it again. I thought it worth a mention on the website. The version I have, I think it is a Mistral, works for my 19 but is probably made for bigger cockpits and I am sure it will be suitable on all the 26 footers.
It is a very well made item and it provides high quality weather protection and extra storage space. It is made from a light material, both in weight and tone, and sitting inside it is a pleasure - the windows in all directions frame the scenery in a most pleasing way. It packs up quite comfortably into an IKEA bag with a separate bag for some steel and plastic poles. Yes, it is a bit of a faff to erect but once you get the hang of it, easily doable in five minutes or so. I motored with it up but I would remove it to sail.
The pictures aren't great. It's not a perfect fit yet - a bit shabby - but it is easily adapted to all cockpit sizes and I will learn to tweak it in future.
I have no commercial interest in Habitent but I would recommend the product: I am really pleased with the build quality, value for money - when compared with the cost of a tailor made canvas system - and the practical gain is significant.
