Can I build rudders for Eclipse using three layers of 16mm(3/4in) C.C. foam with 600g(18oz) glass between each layer,followed by a couple layers of 600g biax on top and all round the rudder?
I ask this because I've read that Roger used a similar layup for his Gypsy rudders in the UK.
Also ,having read of Garrets misfortune having broken his Gypsy rudder which was ply.
I know they are very strong designed as per plans with ply/glass ,but I have the extra foam/glass epoxy and it will save me money and foam is easier to shape ...
What do you all think ?
