Excellent job Rick! This is the best info I have seen all week. Riggingsurvey.com just surveyed a 88 Sabre 38 with a MkII. Argonautrigging.com just might sell a MK IV down the road. Keep getting the info out there Harken! Harken U Graduate. Class of 2016.

This is a nice video. I just installed a brandy new MK IV on my Bene First 36.7, which I mostly race and honestly it was a little heartbreaking. But I want to make it easier to cruise. In this video you do a very quick demo of how to remove the drum and such to go to race mode, but it would be very helpful to make a video just about that, and demonstrate how its done on an actual boat, with the control line connected to the drum. Also, how to adjust the turnbuckle. I'm heading to my boat today to try this for the first time.

@@harken Hi guys, great, I look forward to it! My MK IV Unit 1 was installed a few days ago and as I don't have the sail yet, I wanted to convert to race mode for my Monday night race. Overall it went well, probably because I watched this video although it is tricky on board. Here are the snags I ran into, it would be great if you could address these in the video. First, lying on my back on the foredeck I found I had to try several wrenches until I found the right size to remove the outer guard pieces, so tell us what sizes to have ready in advance. Then I found I could not turn the guard to get to the two large screws easily. Nothing that can be done but a heads up would be good. I had not yet installed the control line, so should that come off first? Then the top and bottom parts of the drum came off easily enough. I had to apply some firm pressure to get the halves to come apart once the screws were removed. The screws are pretty small but I saw they all used to same size wrench. Finally, the gate so I could lower the swivel. Although it seems to say everywhere to just turn the screw once to get the gate out, I somehow missed all this and the little part fell out and fortunately the toe rail on my boat caught it! This morning I found the detailed printed instructions, I should have reviewed those more carefully. I have not put it back together yet, and I didn't think to mark which halves are top and bottom. I'll probably do that with a label maker once I figure it out. I'll also get two dedicated wrenches and probably order some extra screws just in case. Underway, using it was just like my Tuff Luff. The bowman expressed concern that the bigger parts would interfere with the sail but the foredeck crew had no trouble raising and lowering the sail, and the cockpit crew never gave it a second thought after the first tack. So I'm feeling better about installing this, and I expect I'll be smiling the first time we head out for a lazy pleasure sail and don't have to lift, lug and flake headsails!

Any videos showing adjustment of forestay tension with the Mk IV? The instructions in the user manual are not clear to me.

ESP is a nightmare when it jams up. Does anyone at Harken even sail???

Its 2020 and these clowns are still using philips head and flat heat screws in a marine environment.
