Swim Platform Extension
 

I am planning on building an extended swim platform for a 1999 Fourwins 278.
I am considering making a mould then making the platform, ( maybe making a
couple more to offset my costs) does anybody have any experience in this
process. I want the platform to be as professional as possible, not a "Stick
on"

I would buy a manufactered extended platform if one were available but
unfortuatly there is none for this model.
