retrieve a series from the bow? are you setting it from the bow? or moving it from stern to bow only when you go to retrieve?
Setting from the bow is generally a bad idea.
moving from stern to bow is possible but going to be a bit tricky - I generally don't recommend it. But if you do that, just motor
straight ahead and pull it in by hand, and yes a second roller would be great (also useful for other uses) but does not need anything more complex than that.
I have twice used electric
winches/windlasses to retrieve, and neither went all that well.
When we tested drogues on steve dashew's boat
we used an really LARGE electric
to retrieve them. The series drogue
burned it up.
On Hawk, we once also tried with our lewmar
3500 lb (oversized) windless, on bow and we took a retrieval line up the deck
to it, and it would trip out (overheat sensor).
The loads peak when you start coming down waves (and decline as you go up the backsides). The peaks can be pretty high. . . . .depends on how long you wait for the storm to decline before retrieving. We tended to wait until winds dropped below 30ish and I was surprised it still tripped the windless but it did. But when you look at anchoring
loads (lower than most people think) vs drogue
loads (higher than most people think) it makes sense.
Everyone I know who uses series 'regularly' just develops a rhythm for getting it in over the stern - pull when going up back of wave, hold while going down front. It takes some time, but is sort of nice brainless work
out in the cockpit
after a storm.
