I guess the bag hat to be rigid and think you will have no other choice to make 5 part mould, each side and bottom or it will be a challenge to get the saddlebag out

The problem is the straight sided and the overlap on the bottom to one side

yes, you are right, that may work but I think not to make the mould to stiff and be carefull not to crack the gelcoat on demoulding

I would do in fiberglass, I check your video, but I don't if I must to do with the mould open and leave a dry fiberglass for close and seal from inside?

Thanks for your advice

I have 3 and 4 part moulds, created flanges which have a 2cm polished flat (like a U Channel profile) on the edges outside and I seal them with gum tape  only having to put a bag into the indise as usual
Other people bag a mould like this as a mould which is definetly easier but time consuming with more bagging required

but this is without bag, is fiberglass no carbon fiber...

have you thought about doing 2 parts , angeling the sides/rounding and glueing them together with glassfibre tape
One mould for the back and one for the font
A single multipart usuable mould will be a lot of work

You could then sand off the seam edges, fill them abit and spray the lot
much easier that way

I did that on 1989 for bike saddle bags with polyester and hand layup :-)
