Harken MkIV vs MkIV Ocean

[bigd14]

I'm planning on replacing the janky old ProFurl jib furler at the next haulout. I see that alot of people really like their Harken furlers, but I have two options to choose from: the standard MkIV or the MkIV Ocean. I have watched the Harken videos explaining the models and I understand the differences. It appears the Ocean model would suit my needs and is considerably less expensive than its counterpart. However; I am wondering if anyone has real-world experience with the Ocean model vs the standard MkIV. I doubt Harken makes any sub-par products but I want to avoid any disappointment if possible.

Thank you.

The double extrusion enables racing crews to change headsails without being bareheaded at any time. It requires skilled choreography.

I can't see that function necessary for cruising boats.

Fisheries Supply has both versions on display in their rigging dept. In addition to the single sail track, I believe the Ocean extrusion is round vs "airfoil" shaped like the racing model, so maybe a bit more windage. Also some of the swiveling parts (halyard hoist, for example) have fewer roller bearing tracks than the pricier model. I don't know if this would affect performance and/or longevity, but there are some differences.

Both riggers I spoke with assumed I would buy the Ocean model for my boat and usage, but I decided to rebuild my Harken Mk I instead.

Added...I just watched the video--it already covered the things I mentioned. Oh, yeah, they claim the round foil results in easier furling than the oblong airfoil shape.

@Guy Stevens You mentioned elsewhere that you like the Harken Mk IV furlers. Do you have an opinion of the Mk IV original vs the Mk IV Ocean model?

If you go the MKIV route, purchase a few of these. The bottom flange will be the first thing to go and that secures the furling line. Quick fix if you have the part. Odd that something so important is so flimsy.

Anybody ever used Sailing Services in Florida for rigging? They seem to have a good price on a furler package including new headstay and turnbuckle.

I haven't used them, but I the best pricing I found when going with a MKIV a couple years ago was ordering from the Binnacle. They are a Canadian company but have a US web store.https://us.binnacle.com/index.php?cPath=28_132&sort=&filter_id=118

Living in Canada, I've used Binnacle several times, always with good prices and great service.

My response could have been a bit more clear, I haven't used the Sailing Services folks in Florida, but I have used the Binnacle a handful of times. They tend to have very competitive pricing and I've been happy with everything I've bought from them.

For the MKIV, I recall I bought the furling unit from them, but I needed to get the toggle or some other needed install accessory from Defender or WM as they didn't have the part I needed. I'm ok with that.

Thanks for the Binnacle recommendation. Definitely competitive pricing.
