Hi anyone know what all up weight of an alloy Delta is on it's trailer?

With or without engine!...
Year,
What model...

I weighed mine last year on a local weighbridge and it was 540kg it is a 1600 x flow alloy hull. However to be accurate go to your local weighbridge, or local scrapyard (that is who I used) and they charged me £10.00 . This is the Boat + Trailer + the usual fenders, paddle, extinguisher etc.
Hope this helps.

delta ray, the alloy Delta was almost without exception made with a 1500 pre X flow - many of which have been replaced by the 1600 X flow (similar weight).
