Addem 100 Posted May 6 Share Posted May 6 Just looking at the 1050 for sale reminded me to post this. Two years ago we wrapped our boat dark blue. Looked beautiful. Until bubbles started to appear on the hull. Surveyor tapped and concluded delamination. He said he was working with another boat with same issue. Long story short and $000's later have just stripped and repainted. Turns out the builder didn't put enough effort into prep between layers and the heat generated by the sun on the dark colour encouraged separation. It occurred mainly in the fairing compound so a lucky escape. Not really anything to discuss just offering a warning to anyone considering a dark paint job to think about the risks. Wish I'd known. 1 2 Quote Link to post Share on other sites

Sure old style carvel planked boats with caulking in between the planks would usually be painted white, as dark colours were said to attract too much heat and open the planks - but then again I seen plenty of Pommy carvel planked boats painted dark colours. Had a black hull on my previous boat. GRP 70's built. No delamination issues. I'm no boat builder or technician, and probably prone to 'Bro Science' LOL, but if a dark colour hull is enough to delaminate a Farr built with modern methods, then it was built like sh#t. 2 Quote Link to post Share on other sites

Guest 98 Posted May 6 Share Posted May 6 Part of build quality is adhering to the specification of your materials. Some materials strength and durability is affected by heat. Generally Polyester fairs better than epoxy. Industry standard practice is to avoid dark colours where expansion/ contraction is detrimental. If your back pocket doesn’t mind , have at it. Eg certain cedar profile weather boards an human obsession with black. Bad building practices just make degradation faster. West 410 not recommended with dark colours. YMMV.

harrytom 653 Posted May 6 Share Posted May 6 looked at a farr early 90s at pine harbour,very cheap until we talked to the broker,full of pox and delaminating,only good for parts.White gel coat,its all in the build. Humidity/heat etc was resin mixed right or layed up in a timely manner,all sorts of variables has an effect. As Pricilla posted carvel no issue if built well.Moana laid off Devonport for years painted black Quote Link to post Share on other sites
DrWatson 381 Posted May 7 Share Posted May 7 There are certain foil wraps that were not available for our Pogo. Too dark. By boat 50(?) they had changed the foam sandwich (I think) and a palette of slightly darker colours was added - still no black or dark blue, tho, afaik Quote Link to post Share on other sites
John B 106 Posted Tuesday at 09:53 PM Share Posted Tuesday at 09:53 PM John Mac Farlane did a boating article on colours. As I recall there was a surprising difference even between white and gray let alone the darker colours. Then again , our 49 yr old boat is blue over cold moulded kauri and a boat cloth sheathing, paint job needs to be done ,patches etc, but its 20 yrs old and serviceable. Waitangi is glassed, incidentally. Quote Link to post Share on other sites

But then again.. how many black hulled yachts do you see sailing in pommy land actually get to see any sun with any heat? My kauri carvel planked hull is kept gloss white and I see very minimal seasonal movement... Quote Link to post Share on other sites

Well, Global Warming will fix that. Pommy land be the new Miami? 😆 1 Quote Link to post Share on other sites
