[Rhodes22-list] Genoa too long for my GBI furling tube

[Roger Pihlaja]

Mark,

OK, thank-you, now I understand!  I will have to look at doing something
like this with my Harken Unit 0 roller furler.  If I could avoid having to
connect & disconnect the forestay from the masthead when I trailer Dynamic
Equilibrium, it would significantly speed up my rigging/unrigging process.

So Bob, if you are still listening to all of this; go to the hardware store
& buy a piece of aluminum tubing with the same OD as your furling tube.  Cut
this tube to the additional length required on your forestay.  Take your
present furling tube to a welding shop that specializes in MIG welding of
aluminum & have them weld the additional tubing onto the end of your present
furling tube.  Tell the welder that the joint is going to be subject to a
combination of tension, compression, & torsional loading & that you need
100% weld penetration.  Be sure to have them grind the weld joint smooth.
This will provide the additional luff length you want for your oversize
genoa.

But now, if you don't disconnect the forestay from the masthead, the furling
drum will stick out about 2 feet beyond the butt end of the mast when you
trailer the boat.  The furling drum will be supported only by the furling
tube as a cantilever load.  The furling tube wasn't designed to be loaded in
that manner.  The furling tube isn't sufficiently strong to tolerate this
sort of load for very long.  If you don't support the furling drum; then,
you may bend your furling tube as you drive down the road due to aerodynamic
loading & vibration.  I would expect the furling tube will crack & fail in a
short cycle fatigue mode if you don't support the furling drum.  So, for
trailering, go back to the hardware store & buy yourself a piece of PVC pipe
or a piece of wood that fits tightly into the butt end of your mast.  You
will have to rig up a way to secure your furling drum to this PVC pipe or
piece of wood when it is sticking out of the butt end of the mast -
something as simple as a bungee cord would probably work just fine.
