Danno-

Hmm- Can you explain "fear of damage of trailer rollers on hulls"?? About 70-80% of the weight of the (typical) cat is at the front beam- IDEAL place to support the boat (you can see the aluminum "strut" that runs from the deck below the front beam to the bottom of the hull if you look in your ports) is in this area fi supporting the hulls OR you can build a "support" that actually fits under the front crossbar so the hulls take NO load while trailering (they just "hang in there"!)- This is what I have on my Taipan. If you don't want to do that you have 2 options- a "double roller" system (like many of the powerboats use- 2 rollers about 4-6" apart w/ plates at each end and then the plates rotate on a bracket that's fitted to your trailer crossbeams. Other option is to use "bunks" (at least in the front) rather than rollers to spread the load (I would use heavy closed cell foam between hulls and cradles if you buy them if you custom make some to fit your hulls this isn't necessary).

With your rear beam 10" behind the rear of your trailer it will be hard to get a stable rear mast support that far back (that P 18 mast is HEFTY!!- I know! It's longer and much heavier than my Taipan mast). Wait, I just got an idea- Just go to Tractor Supply, Northern Machine (?), JC Whitney and get a 2" reciever for a pickup bumper (meant to be welded/bolted to bottom of bumper- basically just a tube w/ flange on top)- weld this securely to the rear of the trailer (may want to have them add "fillets" so it won't "twist" or another bit of tube to prevent the twisting) and then get a "pickup bed extender"- they sell them so you can carry long things in the back of your pickup and they will be supported- like a Jon boat, ladder, etc.- Plug it into the reciever, adjust height, rig a cradle on top and there you go! Might even have to shorten or drill another hole in even!

Other option that would probably be stable enough would be to take 2 pieces of angle iron (about 1.5" on the flat and 3/16" thickness) or tube(1.5 " sq., 1/16-1/8" wall), weld/bolt in a "V" running from sides of trailer, over/under rear of trailer with tip of "V" at 11" behind rear beam. Weld (stiffer) or bolt plate on to bolt your current mast stand into.



I can send you some pics of my Taipan trailer if you send me your E-mail and tell me your server "limits"-
