what isit that you want to do with your 33 ?
I can suggest this or that, but knowing what your intentions are, your goals, i'll keep it to the basics. 1st add 2-3" cowls w/dorades fwd in the head , then add 2 to the aft. of the main cabin, thus giving you air circulation, when weather is nasty and you can't open any ports, add 2 horriz. grabrails in the main cabin's ceiling, add bruce or CQR plow w/roller to bow, make sure you know how your main reefing sys works and use it, add additional reef point or points to your main, you can add small horriz. grab rails in galley and head, you can add safety deck jacks, either nylon or wire, and add a couple of harnesses, add mtg eyes to mast for harness hookup when working the mainsail, paint your deck and cabintop with sand paint for better traction. These are a few basic items that will raise the safety level of your boat and crew, and now tou can venture into the blue. good luck!
