I need some product recommendations. First, spinnaker sheeting blocks for 20' cat, and second, where do I find a spin bag for the tramp?

Hi Eric,
Recommended are the Harken Ratchamatics and we have all the Harken Products right here on our website store ready for same or next day shipping.

Good luck,
Rick
