My 2010 TI came with fairly short plugs for the bilge and amas. In the course of things, I replaced them and the replacements are significantly longer. Pros: they are easier to get in without cross-threading, maybe they are more leakproof>
Cons: Because they stick out further when unscrewed, they seem to be more easily knocked off. I have brushed mine off quite a few times, usually, but not always recovering them. This is hard on the pigtails, so they become even easier to lose.
As a result, I carry spares, because (as I found out the hard way) getting to the water without one of these is a potential trip killer (well, you can plug them with an appropriate diameter twig...)
But, I found that a great place to stow spares is in the grooves that are in the hatches for holding the AI rudder pins (TI pins are too long to store there). Here, in my rearmost hatch (so it is right at hand when I miss one), you can see one long and one short one (without its pigtail). The notches are a little tight; although they work unmodified, they will pinch the threads hard enough to damage them a bit. A little work with a rattail rasp, dremel, or sharp pocketknife could improve on this.
