A spreader is a spar on a sailboat used to deflect the shrouds to allow them to better support the mast.often, there are multiples, called spreaders.the spreader or spreaders serve much the same purpose as the crosstrees and tops in a traditional sailing vessel.. spreader design and tuning can be quite complex.. Sailboat mast spreader we offer a series of gauges to measure the tension in rods from .172 to .375 inch in diameter over a range of approximately 5% to 25% of the breaking strength of the rod and provide an accuracy of + or - 5%..

In a racing boat, you can use this to specify a lighter mast section. the downside of a keel stepped mast is that you have a hole in the deck. hence many cruising boats (hrs etc) having deck stepped masts. of course, the one thing you can't do with spreaders is hoist a gaff past them. so for a gaff main, the spreaders have to be above the throat.. The boat we chartered had one rig design feature that has become almost ubiquitous these days—swept back spreaders. heavily swept spreaders in fact, with massive cap shrouds to keep the central panel of the rig from pumping, as there were no forward lowers or even a babystay to do that job..
