Reply to: Nacra 6.0 for kitesailing: getting rid of v-brace and DS?

Message body

[quote=skywalker]Thank you for all your comments.

[quote]If the force is upwards,(kite attached to mast support) the V brace does nothing[/quote]
That's what I think as well. The V brace does not help if the force is in any other direction than straight downward as from the mast. Doesn't the pretension even make the beam weaker for a force pulling in the wrong direction?

The other benefit of removing the V brace/DS would be that I would just replace the DS with an eye bolt to have a neat anchor point for the kite.

Does someone happen to know the maximum tensile stress the sort of aluminum used for the beams can withstand? I could then measure the wall thickness and calculate the maximum force for the bare beam.

[quote]What is the total weight of you and your crew?
What kind of wind speeds do you see? Steady or gusty?
What size kites will you be flying? [/quote]

Total crew weight would be between 300 and 550 lbs (2-3 people)
I would wait for a day with at least 12 knots wind with an onshore component. The wind would then be relatively stable.
I have  7, 11.5 and 17m kites.

Using the jib blocks to steer the kite might be interesting in the future, but for the moment steering the kite with the bar is how I will do it, because I am used to it.[/quote]
