right from the start seldén was founded in 1960 and it has grown from a small company into the world leader with manufacturing in europe the usa and asia precise meticulous work has always been a characteristic of seldén our manufacturing methods tools and instruments have been specially developed to meet the demands of large-scale cost-effective quality production and the high demands of sailors around the world however we still carry out the same heeling tests as we did back in 1965 we started by doing things in the right way and that is how we have continued heeling test in 1965 the righting moment of the boat is measured at 30° heel heeling test today materials change good methods don t unspecified changes can cause failures each rig is carefully designed and sized for the boat in question we base our mathematical dimensioning on the righting moment of the boat and the boat designer s proposed sail plan the wishes of the boat owner determine the way the rigging system is equipped with nearly 50 years of experience we have built up a tremendous experience bank for the use of our rig designers as a result the boat and rig form a well-functioning whole because of this it is important that even seemingly unimportant details on the boat or rig are not changed without first consulting us as even small changes can lead to big problems each mast and boom from seldén has a unique serial number this is engraved in the lower end of the mast extrusion and the front end of the boom extrusion quote this number if you want to discuss details relating to your rig 4

give us the facts the key to a correct rig calculation is the quality of the input data at our disposal this data consists of hard facts plus what we can learn by listening very carefully when talking to the customer the seldén rig fact sheet has proven to be a simple and effective way of gathering all the facts required to calculate the mast boom and standing rigging it is where you note the data on the envisaged type of rigging the main dimensions of the sail plan the location of the chainplates and the righting moment of the boat or the correct information to help us calculate the righting moment the seldén rig fact sheet is available on our web site www.seldenmast.com attention to detail in our search for perfection no detail is considered too small this applies to everything from the choice of materials to stringent testing of the finished product seldén s business philosophy can be summed up as quality thinking and system thinking and a continuous quest to achieve the best possible function for each product this catalogue provides an overview of this holistic approach read on to learn about our mds full-batten system our unique inboard ends the load distributors in the furlex jib furling system and a great many other features and details 5

mast sections c-sections and f-sections loads generated by the crew mainsheet vang outhaul cunningham etc are transferred to the mainsail and on to the mast as the mainsail is designed according to the expected curve of the mast a longitudinally stiff mast allows for less luff curve of the sail instead this sail area can be added to the roach of the sail where it is subjected to the wind and more efficient the longitudinal rigidity of the mast section makes for higher forestay load created by tensioning the backstay running backstays can often be avoided the risk of mast pumping is also reduced mast section c-sections c156 c175 c193 c211 y c227 c245 c264 x c285 c304 c321 c365 section dim mm 156/87 175/93 193/102 211/110 227/119 245/127 264/136 285/147 304/157 321/171 365/194 176/93 194/101 212/109 228/118 246/126 265/135 286/146 305/156 324/169 370/192 iy cm 4 391 558 779 1051 1407 1910 2591 3508 4686 5810 8861 526 709 970 1306 1781 2392 3237 4389 5590 8917 ix cm 4 144 191 257 341 456 614 830 1127 1524 2069 3113 187 254 337 453 613 828 1122 1513 2082 3139 wall thickness mm 3.00 3.24 3.40 3.65 3.95 4.35 4.80 5.20 5.80 5.5-6.4 5.5-6.8 2.89 3.04 3.15 3.40 3.75 4.15 4.50 5.05 5.5-7.0 5.8-9.0 weight kg/m 3.71 4.18 4.74 5.34 6.15 7.15 8.40 9.72 11.44 13.06 15.15 4.20 4.79 5.49 6.35 7.44 8.73 10.10 11.84 13.80 16.61 wy cm 3 42.8 53.6 69.3 86.5 108.0 137.0 172.0 214.0 272.0 324.4 441.5 58.2 70.8 88.2 112.0 139.0 173.0 220.0 276.0 328.8 471.7 wx cm 3 33.2 41.0 50.6 62.0 76.6 96.5 122.0 153.3 194.0 238.7 320.9 40.0 49.8 61.8 76.8 97.3 122.0 154.0 194.0 243.3 327.0 sail groove mm 10 ±0.75 sail groove for bolt rope 5.5 ±0.75 mds car see page 48-49 sail slides art no 511-605 or 511-607 6.25 ±0.75 ­ 511-603 f-sections ra ra/rb ra/rb y rb rb/rc rb/rc rc/rd rc/rd rd f176 f194 f212 f228 f246 f265 f286 f305 f324 f370 see table page 9 x if a traditional bolt rope is to be used a plastic profile art no 535-710 as well as a sail feed 505-526-01 must be added to the luff-groove on the mast for more detailed information on seldén s furling masts see pages 93­107 or sailmakers guide www.seldenmast.com 8
