I'm prepping my J/30 for some mild offshore racing. The boat has never been raced (that I know of) and I need some recommendations on what I should add to get started. I've read all the spin rigging threads on the forum, but had some specific questions.

Here is what I have now:

-spin halyard, topping lift, downhaul, pole - all stock plan to keep as is

-aft snatch blocks - non-ratcheting big snatch blocks which mount to aft pad eyes.

-cabin-top 2-speed winches - all stock. No cleats for spin sheets (don't know if other boats have them or not).

-twings - none!

My questions are:

-twings - I've read threads where people said they could be omitted by running sheets inside lifelines, but I've never been on a symmetrical boat that didn't have twings. What is the easiest way to add them? Is the no-twing option really viable?

-spin-sheets - are non-ratcheting aft blocks OK? Do most boats have a way to cleat off the sheet/guy when not actively trimming? If so, what kind of cleat and where is it usually located? Pictures would be awesome.

Thanks!
