Posts: 3,224 Roanoke Island ,N.C. | You guys have missed the point of the platform swap. The harm to the mast would be done by the increased weight of the platform creating more righting moment on the mast.Has nothing to do with the wires or any of that stuff. That being said I think the HT mast could handle the task fine with proper boat handling.

Posts: 465 FL | If you are concerned about Buckling? http://en.wikipedia.org/wiki/Buckling>3.The boundary conditions have a considerable effect on the critical load of slender columns. The boundary conditions determine the mode of bending and the distance between inflection points on the deflected column. The closer together the inflection points are, the higher the resulting capacity of the column.< add SPREADERS if you are really concerned. | | | Re: F18ht mast on I-20

Unregistered | I see in your original post you have new sails for an I-20. I am not sure if i missed this: is the goal solely to have a lighter mast or did you snap your current stick? I have one more option. I could get a blank tornado section from Forte for just under 3,000 clams shipped. Anyone have experience with Forte? | | | Re: F18ht mast on I-20

Posts: 267 Ocean Springs, MS | I would definitely go for an i20 mast if you can find one. I know someone with an extra I20 stick too. The HT is 3 ft taller and it uses a different mast ball size. I'm sure you can do it but it will be a serious pain to accommodate the change. Good luck and let us know how it goes. Cheers.

Unregistered | I was surprised that the spin bail on the HT was much lower. Did that ring any alarm bells? Make sure you get cash pledges from all those who advised you to buy this mast before you go ahead and rig it. | | | Re: F18ht mast on I-20

Currently my boat is on the beach, rig up, with the dolphin striker tied to a screw-type stake (used for beach umbrellas). So far so good in winds up to 37 kts.

Posts: 3,224 Roanoke Island ,N.C. | Go to the sides/ traps with 2 tie-downs ( stakes, boards trees, signs,etc.) and not your dolphin striker they can bend out. Don't ask me how I know. Plus you get less leverage to the middle, engineer boy. tshan is right about burying boards, I just use 2X 10s or 12s 2 or 3 feet long.
