Maybe you are thinking of a more modern version of Hood. My Sea Furl worked great as long as the bearings were fresh. ????????Grant.
The pictures I've attached may shed some light on the bearing questions.
So I am undertaking maintenance
on my Hood SeaFurl 810LD, specifically bearing replacement. I've worked with Marty Barnett at Hood/Pompanette. She's been pretty helpful.
Purchased our Catalina
30T in May 2014. Newbie to big boats, spring was too short and really didn't have a proper sea trial. Oh well... Our Hood furler
is difficult to furl in, especially with heavy wind
(even pointed in to wind). There is a "hitch" in every rotation. When the breeze is up I have to brace my feet against the cabin
bulkhead to be able to pull the dang furling line.
I do use the furler
as a reefer also, even though technically it's not designed for that. I find that as long as I have solid tension on both sides of the furling line it holds well.
Anyway, I figured I needed new bearings for the drive assembly. Ordered them off Hood/Pompanette website and consulted with Marty. I ordered a pair of "Part 13" from the owner's manual and Hood website, which is P/N H6120 (the manual has P/N 6181-000).
I took the drive assembly apart yesterday. Ball bearings everywhere!!!
But alas, I have 1/4" plastic (delrin?? or torlon??) ball bearings at the top and bottom of the bearing tube. I recovered all of them! However, the P/N H6120 (Part 13) bearing assemblies are not just ball bearings. These have cups/cones (races) and small stainless steel
bearings and a little smaller plastic bearings between the SST ones.
My furler is a little screwy, because it has what appears to be half of a halyard swivel assembly affixed just above the drive unit sheaves. This is not shown in the manual. However, the bearing assemblies on this swivel ARE clearly the P/N H6120. I saw another Catalina 30
with the same furler, and it did not have the "half of a halyard swivel" above the sheaves.
See the attached file for pictures and notes.
It would seem to me that I leave off the halyard swivel, and replace the 1/4" bearings (I would use torlon).
The conundrum: I am not seeing any wear on the bearing tube races that lead me to believe the bearings were a cause of the rotational hitch I mentioned. The sheave assembly is held firm to the turnbuckle tube with 4 set screws. When I took the sheave assembly off, I found 1 set screw missing, and others loose (annual maintenance
note: tighten set screws). I am now wondering if the "hitch" could have been the sheaves wobbling???
I've read the manual even further, and I think I will also have to confirm that the centering collar is located properly, and that the top of the luff sections stop 1-3/4" from the bottom of the headstay wire terminal, and where the halyard swivel is located when the genoa
