I also have the Hood Stoway Main Furling.
Advice above sounds good, but just to add my experience so far......
(Mine also came with no manual hand crank, so I bought one about 5 years ago... rubber seal by the hand crank seems to only last 3 years before leaking ATF fluid)... I've replaced it twice)
It is hydraulic and has no electrical
load type breakers. Flow pressure can be set at the pump and this influences the strength of the furling motor
does not have this and is so powerful that I'm sure it would rip the clew right out of the sail given half a chance.
However I am careful to watch what is going on whenever it is used.
Whatever you do, make sure the system still works in tough conditions and not just light wind
Just a point worth considering.... My system was setup so that the furling motor
put very little stress on the sail, the downside was that in winds over 15kts, it was nearly impossible to furl the sail away. I then altered the pump pressure so that now the sail can be put away in +50kts.
This for me , makes the whole system much safer.
Another tip when furling away, by having the boom offset, you lessen the angle onto the foil and this takes load of the mechanism. Its designed this way. Have a look at the angle where the sail enters the mast and you will understand what I mean. The boom angle only needs a bit of offset, however, if the boom offset is to the wrong side, then the angle into the mast becomes quite sharp.
