As yet no magazine has tested the QuicKutter™, but in the past 7 months the RNLI, VT Halmatic and commercial fast fishing boats have had them fitted. The first yacht to fit one in the UK has recently been hauled out in Gibralter, with evidence that the cutter has been effective and the installation looks like new. Dickies in Bangor have also recently fitted a cutter to a fisher 30.
We also have Naval architects specifying our cutters and stern gear suppliers happy to build them in to their props and P brackets.

It is new technology which means as yet this forum simply doesn't have anyone who has experienc of fitting them present.

I'd love to get the magazines to run a thorough independant test.....they all know about them...we're just waiting

The green river divers knife,
The sharpest knife in the world varies in price at around the £25 mark
Serated stainless from New Zealand.
Yes it will cut through steel wire, with a few hacks. 1 slice through most ropes.
That is as long as you do not mind getting wet in the process.

hello,i have an "ambassador"rope cutter fitted, and was unfotunate to pick up a rope(from a shrimp basket)while on low revs.the cutter did not do its job and i was eventually left with no alternative but to take a dive,to free the prop.
later whilst discussing my plight, other boaters said that rope cutters are not particularily good at low revs. any comments?

Seems to me that we have too many commercial interests piping up here. IMHO it depends on your budget. Any cutter is better than none at all. Following the advice in Sailing Today, which quoted it as the 'best budget buy', I fitted a "ProProtector" last spring. It is easy to fit, would clearly work in many situations (though probably not all) and I have had no problems at all since then. Just lucky? Probably! /forums/images/graemlins/smile.gif

Yes they have, the French disc cutter claims to cut 6mm wire so guess what I did. Yes I hired a lab and put one in a test rig. Gather round and look technical chaps.

The rig was a Denison tensile testing machine and the disc cutter was set up on a 25m shaft with the wire rope pulled tight. The wire was pulled tight on the blade just as it would on a boat and there was no relative motion just as on a boat. The load was increased until the wire severed. So their claim is true it will cut wire rope.

How much load was involved, oh dear 3.5 tonnes. That is lots, certainly In my humble opinion more load than a P bracket or even the hull could withstand.

I fitted disc-type cutters to my previous boat a) because I wanted at least some protection and b) I couldn't afford the exorbitant price being asked for the 'stripper' type.
We picked up a rope on three separate occasions and each time the discs dealt with it perfectly. I am ashamed to say that one time it was one of our own ropes!! /forums/images/graemlins/blush.gif
Don't forget - the more expensive ones have their problems not the least of which is wear on the jaws in sandy/muddy conditions leading to equally expensive replacement parts.

Experiences

We've caught ropes three times - allon the French coast.
1. On th eCalvados plateau very little wind, early in the year. Apparently little swell. Sent crewman down with bradknife and his waterproofs on - with a harness. He found it hazardous with the very slight swell banging his head, very cold and very jellyfishy. It was very difficult to stop the boat sailing forward even with sails down. I'm glad it didnt happen at night.
2. In harbour - 1 metre length of rope jammed prop - not visible from above. Took several minutes to saw through with bread knife.
3. - much the ame as two
4 (just remembered in Norwegian harbour of Sirevag - I think.
No obvious problem but engine vibration in gear.
Hsd boat lifted at Stavanger. Small quantity of rope firmly wound round prop. Easy to remove - but Norwegain water is cold and the people there use immersion suits not wet suits.
Subsequently fitted a Stripper - no problems but odd mark suggesting rope contact at prop root.
I'm glad I fitted one.
