Video showing how the J/109 outhaul works

Post by spelunkerd » Thu Jun 13, 2019 11:50 am

If you wonder how the mysterious outhaul pulley system in the J/109 boom works, or if you wonder why the outhaul line is so long, or if you've lost the outhaul inside the boom, you will want to watch a 5 minute video outlining what I found. In my case I used class II line to route the control back to the cockpit, stripping the cover for the length that is inside the boom. I decided to do that because the unused clutch in the cockpit was too large to hold the small line, and because the pulleys inside the boom are better served with small diameter line. If I had to do it over again I would look harder to find a clutch or cleat that would work with small line, and use small line throughout. Perhaps one could find an insert for the bigger clutch to control small line. Incidentally I found a 14:1 system, not the 16:1 described in product descriptions (my boat is hull #43).

On my Youtube channel there is a playlist with a series of repair videos, all done on the J/109 with a Yanmar 3GMFC engine.

Here is the link to the Outhaul video. If link doesn't work, search the Youtube channel Spelunkerd, "How does a Sailboat Outhaul work?"
