Risky
Brian,At one time I spoke to my dealer about putting an assymetrical on my 146. He was game to cut one for me and was going to talk to Hunter. Hunter never got back to him. I subsequently gave up the idea after I started to see cracks forming where any hole was drilled in the plastic for hardware. I had my first hull replaced (Hunter was good about it) and now my second hull has developed its first crack by a stay (Hunter has not responded after many months.) You may want to consider what adding the stress from a spinnaker might due to your warranty on your hull. Hopefully you never experience the cracking, but it could be worse if Hunter refused to support the warranty due to modifications. You may want to ask them first before drilling holes....Wayne
