Blue Hulled Yachts !

Whereas the Bedu clothes and tents are invariably black in places such as Saudi Arabia. Without maintenance issues, I suppose this is in order to create a draught within.

The worst solar design I have ever suffered from is at Bath University. Their main range of buildings has south-facing labs with windows which hinge at the top. Because the place is built on a hill, there is a least floor's worth of wall below these windows. The sun heats the wall, hot air rises up it ... and is neatly funnelled into the labs by the windows. It's like having a powerful fan heater at every window. If the numpties who designed it had hinged the windows at the bottom, entrained air being pulled out would have created a superb free ventilation system.

tl;dr: Bath blows; would be better if it sucked.
 
I have a dark blue hulled boat in Barcelona, when the boat was in Plymouth for 3 years previously never really bothered me. Once in Med I noticed a big difference in the heat down below. To the point I bought a full light grey hull cover for when in the berth, the difference was really noticeable with the cover on to off. Maintenance wise it's awlgripped but still needs washing regularly, and polishing about twice a year at least to keep it looking ok.
If I had bought the boat for the Med, I would definitely stuck to a white grp hull and probably no teak side decks.

Previous company installed blackout blinds in the training room - in the large south facing windows. The very clever chap who ordered them chose black so that it would be completely dark he said. On a sunny day you could roast a chicken in there, death by powerpoint never happened as we lost most staff to heatstroke by slide 3.

...although in less clement conditions it would also have caught and funnelled in rainwater through any windows accidentally left open!
