Re: Topping lift vs. boom kicker

Or.. you could do what I wound up doing....

I got a new boat!!!

Much nicer than the old one..

New boat had a Selden rigid boom vang.

I use the halyard to hold up the boom when I'm not sailing.

This boom vang is much stronger than the old one.. It all works just fine.

I recommend the new boat purchase path. Faster may be available to help out with the logistics

Re: Topping lift vs. boom kicker

regarding setting and forgetting topping lifts this must be a new technique as I have never done so...I also havent broken a boom yet knock on wood

it goes without saying like releasing the backstay or runners when rounding a reaching mark or whatever that you have to pay attention to what your are doing

I think vangs have been very misunderstood at times even topping lifts...

and used for other purposes than intended

I mean for all intents and purposes like I and others mentioned on the vang thread you can sail perfectly fine on many a boat without a vang, especially low aspect mains and long boomed older boats

however once the leech is stretched you have to recut or figure something out as youll just keep sagging

anywhoo

As a quasi-reef/spillage measure I'd rather flatten the sail and dump the traveler - another reason to also have a good, usable traveler system coupled with a powerful vang.
I think we can mostly agree here either method here can be used to acheive similar results

for example on most of my boats I have always either reefed or when thats not possible just dump the mainsheet

however my "new boat" has an awesome purchased traveller system and is a racier boat so thats the way to do that without messing with the mainsheet so much that would always change the shape of the sail

anhywhoo as always many ways to skin a cat here....

It's like you've watched me sail!

Pull away from the dock nice and close hauled, then bear off to a beam reach and ease out the main and AACKKK NOTHING IS HAPPENING!

Re: Topping lift vs. boom kicker

yes due regard for the topping lift tension must be considered I agree. I guess my point is in the scheme of control lines controlling the sail, maintaining the horizontal axis of the boom between the vang, and the topping lift, once the main is up the topping lift can be snubbed up not bearing the the sole weight of the boom mind you, but take a bit of the pressure off. the vangs downward pressure keeps the boom from rising, and the main sheet maintains the sails profile to the wind. It is a means of spreading the load as it were.
I have been doing it this way for 20 years. But hey, I am open minded, who says old dogs cant learn new tricks. Maybe I have been lucky nothing got wrecked doing it this way all these years...

(of course this is dependant on your point of sail) Strain needs to be minimized on the leach so the outhaul and leech lines can be adjusted to optimize sail shape.
Generally any mainsail should be cut so the boom is horizontal when the sail is full hoist, with no assistance needed from a topping lift. If it is not, then the sail's the problem.

Advising that the topping lift should be used to hold the boom after the main is hoisted, would seem bad advice. For my last two vessels (CS36T and P31-2) and most others I sail, I find the topping lift can be set properly once and forgotten. If you screw up and sail with a tensioned topping lift, with end-boom sheeting you may only break the topping lift, with mid-boom sheeting, you may break the boom. I've personally broken a boom due to a topping lift not being released (some else's boat...).

I mentioned this is a great way to spill wind on an otherwise unreefable main

you spill wind off the leech

the same can be attained by pushing a boom kicker all the way up or installing it to be higher than level however this will give you less adjustment for sail shape as you will be maxed out unless you change the purchase system on the vang part
