Thought about launching from the stern but never tried it. Partly due to worries about fouling the prop or the keel if there's any drift or way on, and partly because it's harder to do without scratching the topsides. Will try it though.... thanks.
After you anchor off from stern, before you walk the chain to bow, secure the chain with a piece of long rode (can use rolling hitch) and tie to the stern cleat. Now the boat is securely anchored from stern (via rode on chain), you can take your time and walk the rest of the chain, around the shroud and secure it to the bow anchoring point. Now, release the rode from the cleat and secure it to the bow somewhere. When recovering, you can bring the rode back to stern and tension it, freeing the chain for you to walk back and prepare for recovery.
