    Hey, could someone please help me with some advice on sewing the WeatherMax80... What we do wrong that causes the crooked seam? 

    Taped seam before sewing

    Attempt 1 was rather good

    Attempt 2 not that satisfying 

    We will redo the second one tomorrow but what should we keep in mind making it better?

    The blue end of the spectrum reflects UV, and remains more colourfast; the red end of the spectrum absorbs UV (so the dye fades quicker), but this doesn't necessarily mean that the cloth breaks down. White (the absence of dye) both lets all colours of light, including UV, into the heart of the fabric and reflects all colours of light equally. I wouldn't worry too much about cloth breakdown in high latitudes, but I would certainly avoid white in the tropics, for both long life and crew comfort.

    Hey, most of the comments about the colour have been from safety/comfort point of view and I agree the dark ones have its advantage. What about the relation between light/dark colour and the durability?

    Here it says:

    * 100% Solution-Dyed Woven SaturaMax * Width: 60" Fused Edges * Weight: 8.0 oz. / sq. yd. * Finish: HydroMax * Water, Dirt, Mildew Resistant

    Does that mean the light colours are also 100% dyed and if they are somewhat less resistance to UV etc? Any opinions on that?

    Not to mention the yellow!

    Safety is improved by coloured sails as well. Grey sea, grey sky and murky visibility make a white sails disappear while a dark colour continues to stand out.

    I find that colours towards the red end of the spectrum are easier on the eyes, both when sewing sails and when using them, and I think this is because they are absorbing the UV, rather than reflecting it into my eyes as blue does. Silver would be terrible, worse than white, but if light coloured sails are desired, cream colour is not too bad.

    White sails are a common choice because white cloth is less expensive to produce - it's not that the cloth is coloured white but that there is an absence of colour - the fibre has not had to go through a dying process.

    Coloured sails can have the advantage of less glare than white sails. I didn't realise how much easier on the eyes they could be until I had some, tan sails both in China Girl II and Ivory Gull.

    A five-year warranty is a five-year warranty.  Significantly, they only give three years on the red, which I suspect fades.

    I wouldn't agree that your present colour scheme looks 'heavy', but if you're used to everyone having a white boat, colours can be a bit of a culture shock.  I'd have a coloured sail, myself, but then, I love colours!  Look at my 'avatar'!

    It has been mentioned that dark color fabrics tend to have better UV-resistance compared to light color ones. My boat's color scheme being already kinda "heavy" will be prettier with White sail, I think. Maybe Silver would be fine also, Royal would be the last choice. Talking about Weathermax 80 color options.

    Here is the current look

    Is the UV-resistance for White actually that bad it should really be avoided?

    I am about to start making a new sail and haven't been able to decide if I should go for Weathermax 80 or Dacron. 

    I read, somewhere, a review that said Weathermax outlasted Sunbrella.  I had a suit of Sunbrella sails on Badger that lasted 11 years and 80,000 miles and were never covered.  They still had a fair bit of life left in them when they were replaced.  So the Weathermax should last at least as long and a lot longer than Dacron.
