Anchor hammering furling drum

A phenomenon I have noticed since I've had the boat has finally taken effect. When the anchor (a 35lb CQR) is brought up the stock hammers the side of the Schaeffer furling drum on the headsail as it comes over the bow.. The anchor needs to come up reasonably vigorously to bring itself over the roller and into its resting position. I find it difficult to do it manually.
A couple of days ago it came up partcularly vigorously and pushed in one of the three stainless steel fin-shaped uprights on the drum. The reefing line on the drum then got caught up on the outside of the fin and it became impossible to haul the headsail in. I was able to unthread the line and sort it out while we sailed because I had others on board, but I might have found it difficult if I'd been solo.
I have occasionally had problems with the line jamming up previously, but nothing too serious.
Has anyone else had a similar experience and do they have any clever solutions?

This doesn't answer your question directly, but...

We have a ProFurl unit.  It's an LCI32.  when I originally purchased it at a boat show (discount), it was an LC32.  A year later I "finally" had it installed when I redid our standing rigging.

The rigger ended up getting extension plates, because I told him I wanted the drum up off the deck.  These extension plates lift the drum pretty far off the deck.  The LCI includes the extension to the LC unit, same drum, just a different height from the deck, with a shorter extrusion length, which works fine for both of my jibs because they have similar luff lengths(110 and 85).

The advantages are that the foot of the jib is actually above the pulpit rail, and there's plenty of clearance for the anchor.  Not the greatest for deck sweeping jibs for racing, but what the heck.  It is VERY good to have that clearance to be able to see forward under the jib when closehauled.

I don't know if Shaeffer makes "extensions" for their units.  The ProFurl website most likely has pictures of their extensions (try a google to get there).

If Shaeffer doesn't you may want discuss this concept with a local rigger and see if you can make something up that would do that, and maybe call Shaeffer to see if it's OK with their engineering dept.

Good luck,

John,
I have a Delta anchor and have the same issue you have with your CQR, the shank hits the drum as the anchor swivels over the roller.  I haven't installed this yet, but plan to this season. I think this should work.....I got another bail, just like the one that is already installed on the anchor roller.  If the second bail is installed behind the original bail, just far back enough to allow the shank to stay in line with the anchor roller frame before it pivots upwards.  This would allow the anchor to clear the drum.  The shank will pivot AFTER it passes by the drum.  Not sure if this will work, but by holding the second bail with one hand, and pushing the anchor forward, it seems to do the trick.

If you receive SAIL or others of those types of magazines, you may want to check out the Catalina advertisement for the new C387.

The picture of the boat is of it heading upwind on a port tack, with a bow on shot from starboard.

It clearly shows the Shaeffer furling unit with the long extension bars holding the drum way off the deck, as I described in my earlier post, with the jib above the pulpit.

Seems that Schaeffer can do it.

If you don't get those magazine "ads" then try the Catalina Yachts website, they may have that particular picture, I just haven't looked there myself.

Just received my issue of SAIL last night.  Here's a clip of the picture Stu is talking about.

:) Thank you all for your replies. Raising the drum certainly makes sense and looks to be the easiest way to go. Its interesting that Catalina have done it on these later models. Thanks for your help.

I meant to say also that looking at the position of the drum in the picture that
Mark and Yvonne sent, I believe the line would come off the drum at a better angle than with it low down where the line tends to rub on the top of the drum and not distribute very evenly.
