Search YouTube there are plenty of them on there for entertainment. Me, I try to avoid them. This is as close as I've come in the last few years and is a testament to the Nacra bow design and it's survivability. An H16 would have been toast in the bow stuff at 0:42.
Thanks. The 5.0 like all of the 16 ft. beach cats I'm aware of have a 2:1 jib sheet setup. I really don't like the excessive amount of line you have to take up after a tack so I tried it one day 1:1 and found that it's more than adequate IMO.

It is my understanding the 2:1 jib sheet set up is more about holding the (stock) jib blocks in the correct angle when in use than the mechanical advantage.
without the jib block secured at the head of the block via the becket it could pivot around and make cleating an issue
Looks to me NacDaddy uses some deck mounted cleat and not the stock cleat/block setup i see on most beach cats
I never thought of it before, 1:1 purchase for the jib sheet makes sense. I found it covenient to move the blocks inwards on the tramp though, with a line from side to side. Meaning probably that I will have to stick to 2:1, by the reason explained by MN3.

Using the stock jib setup on the 5.0 is a PITA whether setup 2:1 or 1:1. Either way the block won't standup such that you can release the jib in light to moderate air, it's only in the OK category in a blow. I even tried using standup springs (not supplied OEM) with less than satisfactory results.
Here is the stock setup that flops around.
Here is the custom setup I use rigged 2:1 but I now run it 1:1 all the time no problem. With the swivel cleat you always have the cleat constrained and oriented such that it can be easily set or released.

This block has no jib sheet tention and is not sitting in its actual position while being used - of course it flops around
i have not used a jib block spring in 15 years - they do nothing of value for me.
using stock jib blocks works for most of the people who sail beach cats -but if you find it problematic and have a better solution (or one that works for you) - cool beans
where there is often an issue is the angle of the block. what works best for skipper doesn't always work best for crew and vice versa - and those little adjustment screws often get seized up after decades of use or non use
One other note on the stock legacy Nacra 5.0 jib block setup. The OEM block is a very heavy 57mm with a grossly oversized envelop and SWL (Safe Working Load) at least 300% beyond what is necessary for the 5.0. A newer Harken variant of the block is sized much closer to the boat's actual needs, is much more compact and will actually stand up pretty well with a spring as it is much smaller and lighter.

Just to clarify, this is not the stock set up! That is my setup, which I reversed the cam upside down, which improves the angle for release on an NA version Nacra, which has a large jib, which needs 2:1 to manage. The image has been in my album for over 16 years: https://www.thebeachcats.…2928eef1585bf7f66ac79947 https://www.thebeachcats.…b55535cdd0724e92f5d06ddd
In light air the sheet is in perfect position to manage and the spring works perfectly. The spring also prevents the lazy block from twisting/tangling.
