grp passerelle

[grafozz]

I had a quote for a grp gangplank at over 500 e and decided that it would not be that difficult to make .
My idea is based on surfboard manufacture , PU foam poured into a strong timber mould , adding carbon tube stringers centre and edges
for strength ,then axial mat and glass/epoxy over. adding sand into the top coat /topside for grip .
anyone tried this ?
sizes 2500 x 300 x 40 mm

Would probably work OK but I would use PU insulation sheet pre-made, e.g. Kingspan. It comes in many different thicknesses and sizes.

Better still might be a honecomb core, used by 'Epoxy Les' to construct lightweight GRP gangplanks out here.
See, for instance: http://www.coretexgroup.co.uk/5.html

If the OP wants more specific details I'll be seeing Les in the near future and will be happy to ask him.

I have a Passerelle made by plastimo. It is aluminium and folds. It is nice and light, but not strong. It is also quite narrow. It is my second, the first having been replaced by Plastimo for gradually bending. This one is going the same way. The Plastimo one weighs 10Kg and is 2m long.

I too would be interested in a honeycomb based passerelle if it were as light as the Aluminium one.

Apologies, grafozz: I quite failed to notice your whereabouts. I have just thrown myself down the companionway by way of penance, breaking several ribs and, worse, spilling an almost full can of Mythos.

'Epoxy Les' is Les Wood, based at Nidri on Levkas island, although he spends many of his working days at the Preveza yards. He's a mine of information on matters grp and a good source of materials. I'm sure he can make a grp gangplank to order.
You can e-mail him at leswood23@gmail.com

May I ask how thick the aluminium wall sections are?

 

[tudorsailor]

The plastimo has box sections down each side with sheet of aluminium inbetween
The problem is the weak point at the edge of the aluminium sheet that takes all the force

I have wondered about putting some kind of rod underneath to increase the support. Basically it is a poor design for something so expensive

Let me know if you want to know more
