Just for reference, we have been using Dyneema D12 for the Jib halyards on the Hobie 16 for a few years. We also use other Marlow braids for sheets. Currently we use the Excel Marstron 8mm for the main sheet and 6mm for jib sheet.

These are Marlow lines. The "D12" is related to the braid or 12 strand Dyneema.

Here is a quote from the Marlow catalog:

Excel D12 is constructed from high modulus Polyethylene (SK75 Dyneema®) 12 strand single braid and is urethane coated for maximum performance. Its tolerance to abrasion is excellent and it is resistant to degradation from ultra violet. This line will also float and has zero water uptake.

Here is the catalog page I refered to:
