I purchased these ultra high modulus tubes from C-Tech to upgrade the wing bars and mast stump on my boat.  I am now planning to upgrade the whole boat in the next year instead, so I am not going to use them.  The tubes have never been used.  Dimensions are:

(2) 1 3/4 inches OD x 31 5/8 inches Length

(1) 1 3/4 inches OD x 13 7/8 inches Length

(1) 1 15/16 inches OD x 6 1/2 inches Length

These tubes are ideal for a home builder or a compression strut delete project.  Originally paid around $500 USD.  Asking $250 USD.  Located New York State, USA.  Will ship anywhere at buyer’s expense.
