I have installed a new tramp on my Prindle 19 using 1/4" dyneema for lacing. I tightened the tramp on a relatively cool and overcast day and it remains rather taught so far, however I haven't placed any weight on it. My question is should I retighten on a sunny, hot day in order to get the tramp "drum tight"? Specifically, how tight does the tramp need to be?

On boats where the tramp contributes significantly to the overall frame stiffness (like H14 & H16), you want it to be very tight. On all other boats, just make it nice and snug so your rear end isn't dragging in the water - it's mostly a comfort thing. Sounds like you got it as tight as it needs to be.

not sure about the prindle but my mystere 5.5 loves the tramp snug and it helps with boat stiffness.
Dyneema is know to have a little bit of creep (elongation over time that does not end) so you may still need to tighten it up from time to time - but this should be pretty minimal
I tighten ever year in the spring .
tension it again after you sail it.
