Removing lazy jacks on F35

Posted by sodaksparrowhawk (sodaksparrowhawk@…>)

Before removing or going to a less robust set of lazy jacks consider
this scenario.

That big main is wet and extra heavy. You’ve just dropped it into
whatever sort of “pack” you have because it’s getting windy and rolly
and you are going to go in an entrance with a nasty swell. You have a
solid vang, of course. Look at the geometry of the mast, boom and vang.
Imagine the weight on the boom of that big wet main and your new pack.
Now imagine the force vector compressing the vang and transmitting that
load to the collar on the mast. Next consider the force vector pushing
the boom away from the cast portion of the gooseneck fitting which is
primarily designed to withstand high loads in the opposite direction.
Now there is a lot of force in an aft direction and that is trying to
rip those machine screws out of the boom.

As the hull pounds and pitches in those swells imagine the huge
increase in the loads Even with the main sheet snugged down that
heavily loaded boom is whipping back and forth and the above referenced
loads increase alarmingly.

Now imagine having the original robust lazy jacks snugged up and
supporting a large part of that load.

Yes, you can use the halliard as a topping lift but it really is fun
clipping it on to the end of the boom in the canditions referenced.

Food for thought only, but based on experience.

Stan, you certainly make a good case for keeping the lazyjacks.
I will probably do that this season, as the Doyle stack-pack would take at least 2 weeks to get (and I’d have to send them my sail to be modified, and loose all that time.)
I just want a faster way of putting the sail to bed.

There is a much faster way to put a sail to bed. Its called a boomfurler, NO LAZY JACKS. Just up graded my 40/40 and it works great. Don’t have a pick yet or I would send it.

The Schaeffer boom furler requires that you replace your boom. It is not inexpensive.
