Experience with these outhaul cars?

[Dan_Y]

I'm contemplating an upgrade to an outhaul car in place of the brass slider I currently use on my '91 H30 boom. I went from a footed to lose footed sail to get better shape and control of the foot. But there is so much load on the slider I cannot flatten the sail without sheeting way out or pointing way up. Has anyone used either the isomat cars from rigrite: NB2-17A or NB2-18A?

Scroll 'bout 3/4 down the page.

Thanks for any input,

I went to a 4 to 1 purchase on the outhaul. Actually, it was an addition of a 4 to 1 after the existing 2 to 1. Wonderful addition; easy add.

Thanks Rick,
I believe I have 2:1 purchase in the boom. Did you add another set of blocks internally or somewhere outside the boom, almost like a Cunningham, except you are sheeting the outhaul instead of the sail?

Throw the outhaul car away and go with a clew strap. Most racers and many cruisers are doing this for loose footed mains. VERY dependable. I've had nice ball bearing cars, and a strap is better in every way (simpler, lighter, cheaper, moves better under load).

My 2 to 1 is internal to the boom. I added 4 to 1 externally. Garhauer blocks.

I have a brass slider (looks similar to a mast track slider) that is captured in the boom track. The slider and has a loop of webbing through the clew cringle and slot in slider. Is that what you mean? Maybe I just need to put some sailkote in the boom track? The additional 4:1 purchase would help.
