Jednym z wa\u017cniejszych wpis\u00f3w ze strony Paula jest poni\u017cszy cytat (mam nadziej\u0119, \u017ce Paul nie b\u0119dzie mia\u0142 pretensji o cytowanie):<\/p>\n<p><span style=\"font-family: Courier New; font-size: small;\"><strong><span style=\"color: #ff0000;\">Can I increase the plate thickness?<\/span><\/strong><\/span><\/p>\n<p><span style=\"font-family: Courier New; font-size: small;\">I am constantly approached by builders who are thinking of increasing the thickness of the plate, either all over the hull or just below the water-line. The thought is usually to increase the thickness by 1mm from the 3 or 4mm plate specified by the designer, to make the yacht stronger.<\/span><\/p>\n<p><span style=\"font-family: Courier New; font-size: small;\">This has  two adverse affects. The first is that the yacht will be overweight, in  some cases by so much that the amount of ballast has to be reduced. This is  often coupled with the other effect which is that by thickening the plate the  centre of mass of the yacht is raised, reducing the stability.<\/span><\/p>\n<p><span style=\"font-family: Courier New; font-size: small;\">In an effort to overcome this some builders over ballast their yachts and raise the water-line, while others just accept that the yacht is tender.<\/span><\/p>\n<p><span style=\"font-family: Courier New; font-size: small;\">On one 40 foot steel yacht, the builder decided to increase the deck thickness from 3 to 4mm as this would help to reduce the welding distortion. Good idea you may think. But hold on, that is an increase in weight of 33%, or in real terms about 500lb. and this weight is acting about 4ft. above the center of mass. This can be represented as 4 x 500 = 2000ft.lbs or nearly a ton extra acting against the righting moment, which meant that the yacht needed extra ballast.<\/span><\/p>\n<p><span style=\"font-family: Courier New; font-size: small;\"><strong>DON&#8217;T INCREASE THE PLATE THICKNESS.<\/strong> Steel yachts are incredibly strong! Most 30 to 40ft yachts could be built from thinner plate. The reasons why thicker metal is used, is the difficulty of welding thin plate, also to resist denting while alongside quay walls etc. and traditionally as an extra margin for corrosion, which has now been overcome with modern paint systems.<\/span><\/p>\n<p><span style=\"font-family: Courier New; font-size: small;\">When designing the Fay 32 we specified 3mm rather than 1\/8 inch plate. Only 3% thinner, but this represents a saving of 160lb overall. Which in real terms means that an extra 180 tins of food can be carried for those long passages.<\/span><\/p>\n<p><span style=\"font-family: Courier New; font-size: small;\"><span style=\"color: #3366ff;\"><em>exception from the FAQ section of www.faymarine.com<\/em><\/span><br \/>\n<\/span><\/p>\n<p>Paw\u0119\u017c jest jedynym miejscem, gdzie grubo\u015bci s\u0105 zwi\u0119kszone.

Jak wspomina\u0142em zastosowa\u0142em trudniejsz\u0105 w obr\u00f3bce, ale za to znacznie mocniejsz\u0105 stal 18G2A zamiast zwyk\u0142ej stali konstrukcyjnej typu ST3. Wi\u0119c Fayka b\u0119dzie mocniejsza bez zwi\u0119kszania grubo\u015bci i wagi. C\u00f3\u017c najwy\u017cej nie b\u0119dzie ju\u017c miejsca dla chudych fotomodelek.<\/p>\n<p>Przy okazji poczyni\u0142em te\u017c obliczenia odno\u015bnie bie\u017c\u0105cej wagi Fayki. Na chwil\u0119 obecn\u0105 to co wida\u0107 na fotkach wa\u017cy ok 5100 kg. Stal w zasadzie ju\u017c nie b\u0119dzie wchodzi\u0142a. Balast to b\u0119dzie 3,5 tony o\u0142owiu &#8211; to daje 8,6 tony. Izolacja, obicie wewn\u0119trzne ze sklejki ok 500kg, meble ok 500kg, silnik ok 250kg, generator 80kg, dwie kotwice g\u0142\u00f3wne 50kg, dwie zapasowe 30kg, \u0142a\u0144cuch kotwiczny ok 200kg, maszt + bom ok 200kg, \u017cagle ok 100kg, liny ok 100kg, AGD, zbiorniki ok 200kg, galanteria pok\u0142adowa &#8211; kabestany, winda, ster strumieniowy, bloczki szyny itp ok 100kg, akumulatory ok 200kg. dodatkowe 2,5 tony czyli 11,1 tony. Wyporno\u015b\u0107 konstrukcyjna Fayki to 12-14 ton (12- suchy jacht, 14 &#8211; z nape\u0142nionymi zbiornikami i zapasami).<\/p>\n<p>Zatem mog\u0119 na razie czu\u0107 si\u0119 komfortowo, bo jeszcze mam prawie ton\u0119 rezerwy \ud83d\ude42<\/p>\n<p>Ale bardzo si\u0119 ciesz\u0119, \u017ce ch\u0142opaki mnie spytali o problem wagi, bo w ko\u0144cu zmusi\u0142em si\u0119 do oblicze\u0144.
