The STANDARD KFR4.5 is a furler that can withstand a workload of 4.5 T. It is intended for sailboats from 40 to 55 feet. The KF4.5 is a Karver furler of 3rd generation. It is fitted as standard with a carbon / Kevlar® continuous line wheel, a reinforced ABS casing protected by K Krok protection, our 2 in 1 K Snap snap shackle, our remote locking system for the continuous line wheel and a swivel also protected by our K Krok impact-resistant protection. There are many options available to make it unique and perfectly suited to your needs.


The STANDARD KFR4.5 is delivered with a drum and its swivel. It allows furling in complete safety from the cockpit of complementary so-called “flying” sails such as a gennaker, a code 0, a staysail, etc… It is also possible to store an asymmetric spinnaker by equipping it with our KTS adapter.


For more than 15 years, Karver has been shaking up the market by regularly offering new innovations. We are at the origin of the remote locking systems of the continuous line wheel, of the system of quick furling line installation, captive fast pins, friction sheaves with fast pins, carbon drums, … and we are above all recognized for offering the lightest and most compact furlers on the market. This is the reason why we are very present aboard offshore racing yachts and aboard the most efficient yachts such as the Imocas which are equipped with more than 70% of our furlers.
This 3rd Karver’s generation of furlers definitely places them in a pioneering position.

Weight: 2.145kg

Boat Size: 40-50ft

Working Load: 4500kgs

Breaking Load: 9000kgs 

Major innovations :
– Patented carbon & Kevlar continuous line wheel > Resistance, better grip, less wear, aesthetics, weight gain, customization possibilities. The weight gain linked to the use of carbon has allowed us to strengthen more essential mechanical elements.
– Karver Snap (K Snap) 2 in 1> 2: 1 friction sheave + snap shackle > Very compact & resistant. The only snap shackle on the market to actually hold the full load. The friction sheave will be particularly useful to position your furler on a bowsprit in complete safety.
– The K Kroks are silicone impact-resistant protectors that we have installed as standard on the ABS casings and the swivels of the Standard, Classic and Structural versions. These new ergonomic protections will effectively protect the boat (hull, deck, mast, etc, ..) and the furler itself.
– Aesthetics : Black range, carbon, mirror polished stainless steel, hard anodization of aluminum.

Other new features :
– Wide continuous line wheel available for KF1.5, KF3.0 : More torque for less effort and more power….
– New opening system for captive fast pins that are more ergonomic, more reliable and easier to clean.
– Replacing the swivel shackles with lashing eyes. More compact, lighter and more resistant.
– Possibility to add a wood veneer on the continuous line wheel and / or on the carbon housing
– Always more performance :
o Lighter (carbon)
o More compact (K Snap and lashing swivel eyes)
o More resistant (carbon)
o Easier to use (new low friction bearings / new fast pins / Snap)
o Easier to maintain (new design )
– Reinforcement of the remote locking system of the continuous line wheel. Possibility of not ordering this standard accessory.
– Definitely the best quality / price ratio on the market

Karver standards kept
– Automatic “loosening” of the furling line when it is not under tension : limits wear, avoids burning your fingers.
– Quick installation of the furling line (Karver invention since 2003!)
– Standard delivery of the automatic lock that can be dismantled in a few seconds (Karver invention since 2011… criticized by all our competitors… and now imitated by all !
– List of XXLong accessories including carbon housing, KTS, cableless, 3: 1 friction sheaves, optional 2:1 blocks, clamps, etc, …

Looooves her crazy new ball
Color: Orange, Color: Orange
Our 90lb mastiff/boxer mix Indie is very playful, curious and energetic. She needs toys that engage her and keep her busy. This ball does the job! We’ve had it for less than a week. Here’s what I love and what could be better: PROS: • She dog loves it. She whines for it. She gets absurdly excited when I get it out. She’s a bit of an anxious dog, but had zero problems with it inexplicably coming to life. • It lasts a while on a single charge, so it keeps her busy for a good long time. The longest we’ve used it at a stretch is an hour. • It’s pretty durable. She’s a super chewer (destroyed every “non-destructible” toy we’ve purchased for her), but the actual ball is hard plastic. She gnaws on it and it gets scratches, for sure. But she’s not going to chew it to pieces. • On carpet, it’s reasonably quiet. • It comes with a replaceable silicone button. • It’s easy to charge…just pull off the silicone button and the charging port is inside. • The silicone button is flush with the ball’s hard plastic surface, so there’s no way for her to pull the silicone button out and swallow it or get to the charging port. CONS: • Cover is worthless if your dog is a chewer. It goes on like an envelope with a Velcro closure. We took it off immediately. • Without the cover, it’s very noisy on hardwood floors. To us, it’s worth it. (Though, I work from home, so I might feel differently after the holiday vacation.) • She’s an XL dog, so she can fit the whole ball in her mouth easily and accidentally chomp down on the button and turn the ball off. Not a big deal, just something to know if you’ve got a Lab or larger dog. • With extended playtime, the two halves can come unscrewed, especially with a large dog who uses their paws/jaws on it a lot. Thankfully, it makes a loud buzzing noise when this happens, so we know we need to take it from her and screw it back together. Is this a potential danger? With the rechargeable battery inside, I’d say yes. But we also don’t let her play with this toy without supervision. So keep that in mind. Bottom line: It has its drawbacks, but it keeps her entertained and seems like it should last her at least 6 months with supervised play. Which is honestly REALLY good when we’re talking about Indie, Destroyer of Toys. I’d buy it again.

Difficult/impossible to unscrew plastic cups (in order to recharge the vibrating/blinking device)
Color: Orange
Generally, I don't leave feedback on items purchased. However, in this case, I feel compelled to do so in hopes the mechanical engineers (of this product) will take my input to heart and ultimately modify it. First the pros... - I have 2 high-energy dogs (Jack Russell Terriers) who love their toys (e.g., chewing bones, tug-of-war, etc.) but usually get bored with them rather quickly. - This interactive PetDroid ball, however, keeps them busy for a long time. - In fact, my smaller dog (Max) knows its storage location and sits (as early as 6 AM) in front of the cabinet so that I give him "his ball". It keeps him busy for up to 1-2 hours at a time. - Max is literally addicted to the PetDroid ball... his determinant play with it makes me laugh all the time. Now, the cons... - After several days of play, the exterior looks chewed up quite a bit. That's no problem though. - Unfortunately, the interior "threads/grooves" of the two plastic cups (for closing/fasting) are very tiny. - Thus, after an hour-long hard play, it is almost impossible to unscrew the 2 plastic cups in order to recharge the interior device. - It appears the 2 cups somehow come off track and get realigned from the inside. - At that point, I cannot unscrew the PetDroid ball in order to recharge the device.... and without the blinking/vibration, this toy is no longer fun for play. - Ultimately, I had to place the bottom half of the ball into a vise and then use a plumbing wrench to untwist it. Proposed Solution: - Increase the size of the plastic cups' interior threads/grooves so that they won't get realigned/come off track. - This would mitigate the current dilemma of NOT being able to unscrew the ball in order to recharge it. In my view, this should be a relatively simple fix and significantly improve the durability of this product. Thank you for your time.

Good fun and entertaining!
Color: Orange
A really fun interactive toy for your dog! It's pretty erratic and really gets him chasing it. The included soft cover was kinda hard to install and then it's hard to turn it off and on with the cover on, I feel like the cover didn't really improve it at all, sure it's louder without the cover but I feel like dog also likes it that way, he likes loud squeaky toys and this thing making a bunch of noise is appealing to him. We have mostly hardwood floors so it really gets moving, I'm sure on carpet it would be a bit quieter and maybe even a bit slower to move around but on hard smooth surfaces this things can really get zipping around abd get some speed to make him chase it. Overall a fun and entertaining toy.

Not the Fetch-Fest I Hoped For
Color: Orange
I had high hopes for the PetDroid Interactive Dog Ball, especially with the newly upgraded features and promises of durable, motion-activated fun. Unfortunately, it didn’t quite live up to expectations for my furry friend. Here’s why I’m giving it 2 stars. Promising Features, Lackluster Results The idea behind this toy is fantastic: a durable, motion-activated ball that would entertain my dog without much effort on my part. The ball is supposed to roll around on its own, keeping my dog engaged and active. However, in practice, it just didn’t capture my dog’s interest. Durability I will give credit where it’s due: the ball is well-made and seems durable. It can withstand some rough handling, which is great for more aggressive chewers. Unfortunately, durability doesn’t mean much if your dog won’t play with it in the first place. Motion Activation The motion activation feature is hit or miss. While the ball does move around as advertised, it didn’t seem to move in a way that intrigued my dog. He gave it a sniff, watched it for a minute, and then walked away, unimpressed. I tried multiple times to get him interested, but he simply wasn’t having it. Lack of Engagement The biggest issue is that the ball just didn’t engage my dog at all. It might be more suitable for a different personality type or breed, but for my pooch, it was a total flop. He’s usually quite playful and curious, so I was surprised by his lack of interest. Final Thoughts Overall, the PetDroid Interactive Dog Ball might work for some dogs, but it was a miss for mine. If your dog is easily entertained by automated toys, it might be worth a try. However, based on my experience, I can’t wholeheartedly recommend it. Pros: Durable construction Motion-activated as advertised Cons: Did not engage my dog Motion activation wasn’t intriguing enough Might be more suitable for specific dog types or personalities If you decide to give it a shot, just be prepared for the possibility that your dog might not find it as entertaining as you hope. For us, it’s back to the drawing board for a more engaging toy.
