SHAFT SHARK line and rope cutter for your prop & shaft
I am looking for some personal use stories on this device (Shaft Shark). One of the concerns I have is how effective is it and is the drag all that noticeable.

I have had a couple if different rope cutters. Had Spurs on one boat and a Shaft Shark on the current boat. They work great and I have not felt any drag from either type. Good insurance.

I have Sharks...never used them that I know of and they seem like a good product. Simpler and less parts than Spurs, which I've also had.

I have the Shark cutter. I have never noticed any additional drag from it. It is hard to say how often it has worked, once that I am quite sure of, maybe more often that I never noticed? I do know I have never had to diveonit to cut a line, or found a like wrapped on a haulout. They are pretty much maintenance free and very sharp, always remind divers that they are there so they can avoid getting cut.

I have the shaft sharks. The outside diameter is not much bigger than the prop hub, so its unlikely it has much of any drag. I know mine has "worked" at least once and it has never "not worked". (Never had a line wrap around the shaft tightly) They may or may not work all the time, its a last ditch defense.

Shark or spur
I have had both spurs and shark on sail and power boats over many years. Both were effective, but had several occasions at haul out when I discovered all or part of a spur was gone, necessitating replacement. Never happened with the Shark, which, as noted, are much simpler. Never noticed any drag. However, when I did back up over my dockline (which was dumped in the water by an over eager deckhand), a diver was needed. And you certainly do have to caution any diver--they are sharp!! Wouldn't cruise without them here in the Northeast.

I think Practical Sailor Magazine did a review of line cutters. They decided that the bypass type, like Spurs, were a little more effective, but not much. The knife type are easier to install.
I had Spurs for 28 years and never had a problem with getting tangled in line. I did hit and cut a floating line on at least one occasion. Usually you just won’t know it has worked.

I have a PropProtector from the UK that works fine and costs less than half of what a Shark costs and much less than Spurs.

Cost around forty bucks and looks kinda flimsy, plus you have to replace it frequently, I've had my ProProtector on for five years, works good and still looks new.

This Shaft Razor has 2 cutting surfaces and comes in 2 pieces so it can be installed without removing the prop

I had the shark on my main ship 390 and it saved my boat upon entering snake Creek at Islamorada when I ran over a line in shallow water and in the narrowest part of the channel with no room to spare. I felt it hit and then it spit it out in a split second. I’m sure it did not affect the performance of my boat and I will not sale in the keys without one. I now have a Hallberg Rassi sail boat and installed the shark on that boat as well.

I had a set put on my ingle shaft a couple of months back, and I believe it worked the other day when there was a sudden rumbling down below while running at 15 MPH. I immediately stopped and checked the engine over and then slowly brought RPMs back up with no farther issues. My guess is the SALCA was doing its thing.

But its not much more that a zinc anyway and I think you could leave it installed when the zinc is exhausted and just place a new zinc firward of it. I cant imagine that exhausting the zinc would allow the cutter to come lose? But I have never seen one to examine the construction. The cutter is SS.

I installed the Prop Protector in January 2016. It traveled thousands of miles doing nothing, I was not expecting much from it. And we cruise in the Chesapeake, Albemarle , New England and the ICW , so we have experienced with dodging pots. Last summer we spent almost 8 weeks in the Erie Canal, Rideau Canal, St. Lawrence Seaway and lake Champlain. No pots! But upon return tot he sea we had a big thunk under the boat. No change in RPM, no vibration, no change in speed no sign of anything in our wake. When we were hauled out for bottom paint a month later we could see that the prop protector blade was bent in between two prop blades. Clearly it had done its job at some point . This spring it has worked once in the St Johns river and once in the Pasquatank. I'm now sold on them!
