Blue versus white hull for liveaboard?

White hull easier (or more forgiving) to keep looking good and cooler.

Blue hull needs a bit more care and you may need more windscoops in warmer climates to keep it cooler, but they look very very smart. :cool:

It wouldn't put me off the right boat.

My 361 is now fairly well equipped and I guess there's a lot to be said in casting off and changing later, if needed.

Anyone will confirm that they have come across unbelievable bargains once on the cruising circuit. I myself came across a Hallberg Rassy 352 for less than half the going price because of an emergency (health) sale in an out of the way place. I had only just bought my boat in Sweden so did not have the cash anymore to buy a replacement. I wish I had waited.
 
I have a white boat, which is nice and cool inside BUT before that i had a blue boat which I took to the Med where it got so hot that it spontaneoulsy burst into flames! Yes, really!! The same happened to a blue car i had too! Whereas no problems at all with a white car.

I think the case against blue hulls is getting pretty feckin soiid with this latest evidence, hm?

My dark green hull showed little sign of spontaneous combustion during our three year cruise in the Caribbean - probably damned lucky we didn't paint her blue. Whew.
I did spend ten days on a blue hulled aluminium Trintella in Majorca which also failed to ignite and didn't even seem particularly hot below. Wrong blue probably.
 
I had a beer in the cockpit of a blue hulled boat once. It also had a dark blue sun awning. It was so hot in there I had to go on deck for a coolish breeze. Unfortunitely on the way out of the cockpit I brushed against the awning and got so badly burnt my heart stopped. A clinical death. I fell over the guard rail but got sucked into the propellor which spun me around then whisked me high in the air where I landed on the back of a passing duck. The duck objected naturally and ruffled its feathers which tickled my nose causing me to sneeze violently. This re-started my heart ... the rest is history.

Gee Whiz I am so bored. Roll on Spring.
 
i’m bored too, but doing a transat on Thursday, from here in cape town to the carib. Or maybe friday. White hull boat. I am dithering about setting off on bad luck friday with the wx being a bit boomy on thurs but i just won’t tell anyone, or put it down as very late thursday.
 
..... that Friday one is the only one I really stick to. :cool:

It's really cold here in Hampshire tonight, so I have a log fire merrily burning in the grate. Interestingly the box of matches I used to light it was blue and the match literally "burst into flames" when struck against the side. :eek:
 
Hm. Were you wearing blue jeans as the fire caught hold, by any chance? I’d be interested to hear if others ALSO wore blue jeans at any point in this thread? OR white jeans, hm? See?

Women become inflamed with uncontrollable passion if a guy takes his blue jeans off.

They use this effect to light their candles. (Heard this from a guy before the invention of the vibrator)

I have tried everything on my blue hull to make it look decent and will resort to painting in the spring. Interestingly enough I was at the boat this afternoon, cold but sunny, the dark blue patch of new gelcoat that I applied in the summer was noticeably warmer than the old lighter blue/chalky hull around it. I got SWMBO to feel it too and she agreed with me!

Astonishingly I am wearing all blue "lounge wear"

Uh oh. I hope things are going well. I encountered the worst storm of my life off Cape Town and I was on a white hulled boat! And that was only one white hull. Yikes!

My blue hull is a devil for scratches. Colour fade seems ok, but probably is a problem long term. Heat absorbtion? Up here it's quite nice;)

I love dark blue, it looks very smart, when in good condition. Not a good colour for being spotted by SAR........

In Med waters, about 3 years for a Beneteau DS, before UV fading forced a paint job.

Go green go green, it makes it easier to spot your boat when under the afluence of inchahol
Woop woop.
No sign of spontaneouuuus combustion here either
3" insulation keeps me cool and warm at the right times

I am surprised by that. My 311 is now 9 years old and has always been in the med. The blue hull polished up fine to the original colour this year so they must vary. I don't think the hull colour on a modern boat affects the inside temperature too much as when the sun is high it doesn't really shine on it, another thing with dark cabin tops though.
 
Muttons

Bonjour,
Thee hull of my is dark blue, I haven't suffer from heat those last 10 months in Eagean sea.
All boat are white like muttons, I like to be different;
Best regards

A little bit of science.
If light shines on a blue hull vitually all the radiation, including the infra-red, is absorbed except the colours which make up blue which are reflected (green and yellow).
If the light shines on a white hull, all the visible colours get reflected but the infra-red components still get absorbed.
The infra-red is the main heating radiation and there is less difference between light and dark surfaces than is commonly thought. For example a highly polished dark surface may reflect more infra-red than a matt white surface.
So, I agree that there is a difference and that white is somewhat cooler than dark colours but not perhaps as much as people make out.
White textured decks can get just as hot as teak....trust me ,I have had hot feet from both!!
 
blue VS white

Hello,

The deck is cover with a bleu kind of non-sleep rubber, beleive you me it's hot as well. (I sail in Greece).

Few sea-water buckets are always welcome.

Thank you for the bit of science, I will, to night, get asleep, a little bit less egnant.

Bests regards.
