Anyone out there with experience lifting around 350lbs of dinghy
with a spare halyard/spinnaker pole rigged like a crane?
I am "cogitating" on the physics of lifting my Avon
10 footer onto the foredeck of my Gulfstar
. The RIB
has a steering helm
and Yamaha 25 four stroke + 10gal tank + battery
...total weight about 350lbs.
I have heavy duty, hydraulic davits
for local lifting and quick deployments but want to put the RIB
up on the foredeck for open water passage
to avoid the following seas and heavy weather
: Crane the dinghy
(fully equipped) (fair weather) from water
, over lifelines
to center of foredeck (pre-formed chocks) using crane action of the spinnaker
pole and a 7-1 purchase
for lifting 350lbs of dinghy weight.
(1) Spare halyard
(5/8in dyneema) to top-side of spinnaker
pole (as topping lift) controlled by 2-speed Barrient 16 on the mainmast.
(2) Snatch block on lower-side (outboard) of spinnaker pole with "lifting" line (1/2in polyester) using a 7 to 1 purchase
block to handle lifting (hand pulled).
Has anyone done this kind of thing out there? Any suggestions/ recommendations. I have tried this rig with a smaller 80lb water-tender (8.8) and the mechanicals seem to work
but I am concerned about the integrity of the spinnaker pole - especially at the mast
contact point and the slide track base with an additional 230 lbs?
I'd welcome any advice/suggestions?
s/v TAKE ME THERE!
