A 10mm braid on braid line on a mainsheet car is not likely to be highly loaded on a small yacht. Especially as it would be expected to be set up with something like 4;1 unless direct to winch only operation (unlikely) So a simple whipping would suffice & I doubt if stitching wuld be needed if the whipping was applied nice & tight, The load being nowhere near SWL. Of course if the line is a cheap one with a loose core then it is very possible that the core can slip through the cover. So line selection is important.A note on seizing alone (without sitching).
It worked for centuries on hemp, but nylon and even polyester shrink too much under high load for it to be secure. Nylon will slip at less than 20% WL and polyester at 35% WL. If used as protection for stitching, the stiching actually holds the load and the seizing/whipping will become loose at about 25% of the WLL. This latter does not matter in a practical sense for most applications, because the line is not loaded that high for durability and stretch reasons, but it is something to be aware of.
For high load applications, webbing is better protection than whipping. IF you do choose a whipping, it must be applied with the line under tension (use a winch) and it must be very tight (serving mallet, not hand tight).

On a different note. Sometimes I doubt that stitching would help. This 14mm dynema cored line was on a cleat & the load was a 2.5 tonne sinker hanging in water when it gave way without warning. 2 crew men could easily have been injured. The outer covering remained on the cleat
