Hi,
the added strakes may first disturb the glass lamination by creating air tunnels asides the strakes strips, second , similar problems with the adhesion of packing tape, if any.
The sharpness of strakes may be lost. see sketch
I suggest to adds these elements on the finished hull as accessories.
Yeah I though about the "sharpness as well and getting the nice right angle against the hul/strake interfacel…and the tape sticking. and giving me good relief.
I hesitiate to add them after the fact unless I took some of the 1oz cloth in the final layer and added the strakes and then did a vaccum bag over the top to get the resin and glass to really suck in close…
