To me no....depends.

For comfort yes, for performance I don't know, you are adding sail area above which is good, but removing bellow. depends how much he will reduce.

Looks like you have a car with a punctured tyre, instead of fixing the tyre you deflated the other 3 tyres, Leveled the car but does not run well!!!

I would still go with the roach and dont change the clew. But I am used to releasing the TL when hoisting and pulling when sail is down.

Trueblue, it looks like your topping lift is fairly taut. If you put a lot of slack in it, so that the line can fly freely, it shouldn't hang up so often. It worked on my previous boat, which had a main with a big roach. I also used a light weight line for my topping lift on that boat, so the wind would tend to blow it aft into an arc. Because of the arc, the topping lift isn't so likely to snag on the upper battens. You just have to remember to adjust the topping lift before you lower the sail.

Thanks for the good advice sailormon - you're probably right and I'll remember to do that next season. It may save me the rod-kicker expense.

Also, if you have the topping lift too tight, it can interfere with the mainsail setting its shape properly, as the leech edge won't lie as flat as it should otherwise.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

That's a good one

Giulietta,

I am not sure which way I will go. But "Looks like you have a car with a punctured tyre, instead of fixing the tyre you deflated the other 3 tyres, Leveled the car but does not run well!!!" really made me laugh. I agree, you could look at it that way.

I am a cruiser at heart, so I may just call him back and say forget the roach. I know that would seem crazy to a lot of folks. But on the Cape Dory forum, it was the other way around; most folks thought a roach was blasphemy.

I have never owned even one new sail before, and now I am ordering three (it's a cutter rig). I am pretty excited, but it's a lot of money, so I am a tad nervous, and probably over-thinking this. Maybe I should fip a coin.

On some racing boat with roach main, they have a sort of spring-action wire that connects from mast top to the TL, lifting the TL up and away from the roach. The wire is flexible thus when boom is pulled down, the TL just tension up.
On my boat, I've seden rod kicker and TL. TL is almost always slacken to avoid the mains roach.

I have sailed traditional boats with and without roach in their sails. It really does make a huge difference to how the boat sails, in many ways a greater difference on a traditional boat than on a more modern boat. The difference is often being able to sail and make progress in lighter winds when traditional boats are at their most challenged converting non-sailing day's to sailing days. The difference is often a flatter sail shape in a blow and so delays the need to reef and the amount of heel.

Beyond that I am not sure that the amount of roach is relevant to your topping lift concern. Almost all coastal cruising sails built since the 1950's have been built with some roach, and no matter what you do, if you have battens, some roach (no matter how small) and a topping lift, there will be some interaction. The only way to avoid that interaction would be to go to a hollow leech and that would be absolutely crazy, far more blasphemous than the larger roach being suggested by your sailmaker.

I don't know what the story is with TrueBlue's boat, but I sail on boats with huge amounts, far more roach than your sailmaker is probably suggesting. Frankly, the interation between the topping lift and the backstay is just not a problem. They are typically set up just the way that you are describing where the hoist of the sail lifts the clew end of the boom and slacks the topping lift. (You may see how that works in the photo that is my avatar.)

Keep the roach, you'll really like it.

Respectfully,
Jeff

I agree, keep the roach, and just learn top adjust the TL. What difference does it make to you to release when sail is on , wnd oull when sail is not on?? 10 seconds???

I have been doing it for ever... really its not that a big deal.

If you can, see how big my roach is, and do you see a vang on my boat??? NO!

A rod-type vang is a cool solution to the topping lift problem because it holds the boom in whatever plane you want without a lift. (Be sure to rig a preventer line to each side deck, then aft to a cleat, to keep the boom from flying around and banging heads.) Another way to deal with the lift problem is to run shock cord from it (about 3 feet up) to the boom (maybe 5 feet forward). Adjust the tension so it holds the lift on one side of the sail. Works like a charm.

A question came to mind......If a boat has a tendency to have a bit of weather helm, wouldn't carrying a larger roach increase the problem?
