[Public-List] Do we need halyard winches?

[Brent Higgins via Public-List]

Hi Guys, 
I took my A30 out sailing for the first time last weekend. We got the mainsail up but didn't raise the jib, because I only have the one port-side mast winch. I was planning to run my jib & spin halyards aft by mounting cheek blocks on the mast, similarly to what's on the website. Then I'd have to install a deck organizer, jammer, and winch on my cabin. I have all the parts, but I do not want to do undertake this unless I have to.
I looked through the old emails about mast winches & running line aft, & several of you said that our boats do not really need halyard winches, that you can hoist the main & jib without them. What're your thoughts? Is this unrealistic and/or dangerous? I am cruising only (and not very well...) in the Chesapeake. Should I run some lines aft or manually hoist the halyards?
Thanks,
Brent
