Hi all,
First, thanks to Patrick for the kind words about the class. How's that boat coming, Patrick?
Next, the core-to-core splice is emphatically covered in the splicing video. If you can't find it, please be in touch with
christian@briontoss.com.
And yes, 3/8" is massive for your boat. 5/16" is too, but as Brian notes it would be too small for the belay, let alone your hands. The best option might be to use 5/16", then splice it into a 7/16" Dacron tail. You'd get lightness aloft, a net savings in cost, and comfy handling. How to do the splice? We haven't published that yet, but you could come to the class...
Fair leads,
Brion Toss
