Fixed Vs Folding Prop

[mickp]

I have just removed my prop ( Fixed 2 Blade ) and am undecided as to fit it back, or to fit a Folding 2 blade Prop of the same diameter and pitch ( Gori ) ( Came with the boat as spare)
What difference will I see if I swop the fixed for the folding my guess is :
A) Slight increase in speed whilst sailing due to prop being folded less drag ?
B) Reduced prop walk ?
C) Less response in slowing under engine due to waiting for blades to open
D) Under engine don’t know what difference to expect.
Can anyone enlighten me as to the advantages / disadvantages between props ?
Thanks in advance.

Did virtually the same thing at the end of last years lay up - replaced fixed 2 blade 15"x12"pitch prop with Gori 2 blade folding prop of same dimentions. It was without doubt the single best thing I did to the baot last year. The Gori prop is better in all areas (though the fixed prop was rather cheap, and the Gori quite expensive). We get a higher top speed under engine - but without any more engine revs, astern is a little slower to take effect but is still positive and predictable. As for prop walk it is hard for me to judge reliably - the prop is on the port side anyway - but I believe there is less. Under sail it is better in every way. Do it.

Gori..... Great bit of kit, my boat it will go astern faster with the Gori than forward!!
So beautifully made would also look great on a mantlepeice!

Depends on your boat and boating style really. I don't think a folding prop will make much difference to a heavy disp. type but certainly would to a moderate disp.( boat that is). If you like to sail every where then by all means fit it but if you motor sail a lot stick with the fixed blade sell the folder and use the dosh to fill the tank.

I changed my fixed 2 blade to an autoprop a few years ago. I wouldn't go back mainly because of the extra control in reverse and the ability to stop on a sixpence which I find invaluable in a marina.

check the condition of the Gori as I would only expect the fixed 2blade to be preferred if the Gori had worn pivots or gears

Fitted 3 blade Gorgi some 6 years ago, now after 15,000+ miles still no signs of wear on prop bearings,blades and hub nor have I had any troubles with gearbox etc.
As others have said a great boon, I have not regreted fitting it or its cost once.

I've tinkered about with props on the Moody, Mick. Posted something a year or two ago. Search the board for 'Radice'. The Radice's ok; the Gori's supposed to be better but when I bought mine 5yrs ago, they didn't offer one at 12" dia which was what I needed.

Thanks all for responses, have now identified folding prop as a Radice and not Gori as first thought.
Folding prop seems to have more advantages over fixed.
