well, it already has an adjustable backstay. i have nice harken performance blocks for the jib ( and am getting equal quality harken hardware for the main ). i have nice hardware for a vang, too. i got these nice blocks, including the ones for the vang, for free from that boat i scrapped. the traveler parts, already on the boat, function very well. they don't seem to be cheap, at all. so, i am ahead of the game, there. that saved me a bit of money i would have had to spend, otherwise.
there is no topping lift, however. the boomkicker, if nothing else, will be simpler to install than a topping lift, simply because i won't have to go aloft. i have never had issues with the topping lift on my holiday20 but posters, here, have listed some benefits to the boomkicker and they seem to make sense, to me.
to be honest, looking at the boomkicker, it's not a complex unit. i could fabricate one. i have been consdering it. then again, i do have enough other stuff to do on the boat so, maybe, it might be more time effective to buy while it's on sale.
i will look on ebay and craigslist for an idea of how much i might get for those winches. that was a good idea. thanks.
