I will try grab some 3mm or less gibbon ply.
I'll beef it up with supports like grey matter and fiberglass the deck.

If I cant drop the center beam then I don't think I will make min weight. So clariforcation on this rule is important as I intend to order a tramp designed around this factor.


If it isn't a change then old rule has 2 loop holes..
It isn't clear as the center beam as compulsory only that you have to have a rear and main beam.

Also according to the rules they do specify aluminium for the main and rear beam but they do not specify what material the center beam should be made of only dimensions are listed...
has anybody used carbon tube??
Unless someone else had already done this I would be hesitant as I belive its a loop hole that was unintentional..
Anyone care to argue the pros and cons further??
How far could you go. Could a pool noodle constitute as a beam???

Still I need to establish the rule change first before trying to exploit a loop hole...
