Hoist heights genaker in other classes

As a reaction to B roberts claim that genaker hoisted above 40 % above the hounds will break the (alu ) masts I checked a few masts.
<br>
<br>Nearly all come in at 60 % above Hounds and yesterday when I sailed my boat back to my club via 40 km upwind beat in heavy chop and 20 to 35 knots winds. I passed a club race where all the boats (F18's and F20's) pulled a genaker in 35 knots winds. All boats where okay so I guess that 60 % above hound is okay for alu masts.
<br>
<br>Goodall adviced Hoist height 7550 mm will put the hoist height around 60 % on the Taipan 4,9 8,5 mtr. high mast depending on the height of the mastfoot.
<br>
<br>Or around 45 % on a 9 mtr. height mast depending on mastfoot height.^
<br>
<br>60 % on a 9 mtr mast come sout at around 8,0 mtr hoist height.
<br>
<br>Just as extra info

If one uses a second set of spreaders at hound height.. Then one can go masthead.. (not that Im suggesting a 9 meter masthead kite just yet)..
<br>The spreaders arent that expensive as one doesnt really need them adjustable.. Also its only a slight increase in windage..<br><br>

We have sailed the stealth for four years with ahoist height of 7.4 m on an 8.4 m mast, Our hounds point is very low, from memory about 6m, we have never broken a mast, we recently increased hoist height to 8.1 m and broke the mast, however I believe that if we raised the hounds point we could go to 8.1 m, personally I'd not regulate this measurement, the manufacturers will place it where they think its safe, and will have to warrant that it works, if we must regulate it place it about 50cm from the top of whatever length mast we decide on. I'm sure that new masts can be made strong enough for this and grandfathered boats will be compromising all over the place anyway. I really believe though that if its unregulated the manufacturers will very quickly find how high it is possible to go without breaking masts. <br><br>
