... John, Sharp looking hull! Your cabinet building skills shine again. The hull looks pretty long. Are you even going to have a front runner plank? Keep...

yes i plan on having another 5' out front with a springboard. The runner plank is 18' wide....

Thanks for the update. I am ready as one of your pushers in the Am Cup in 2008. Meanwhile I am testing a new front end on my Fed 5. Stability and steering...

I forgot to mention that the boat will be about 25.5' LOA. It will have about the same foot print as Phils boat pictured in the background on the front page . ...

John Thanks for the plug. How do the Aluminum front ends look. I don't think they are strong enough. I would like to put some side gussets on them. How much...

Frank I have it mounted . Check out the new photo. It looks great thanks!I will need to mount the wheel on the dirtboat front end and see what can be done for...

John It looks great. Stick an axel in it and see what kind of axial load it can take. Give me some gusset dimensions and I will send you a gusseted one to try...

The wings require a large platform for stability. The previous boat that it went on was about 350lbs and had a footprint of 18.5' long and 16' wide plus the...

John What about adding a front spring board and new rear axel to get the 18.8' x 16'? It would be real easy for me to make up the mounting plates for both of...

John Thanks for the info. I was just trying to figure out how to get all of the Manta guys into wings. Frank smith smith <johhnysrocket2003@...> wrote: ...

Frank, using a wing on a Manta Twin would be too difficult due to the weak structure of the Manta Twin and the fact that the mast struts would prevent hardly...

Hi Frank. I have in my crowded garage with two sea kayaks and three bicycles (mtn bikes and a 40 speed recumbent - Trek R200): 2007 Kawasaki KLR650 2004...

Mark I guess my garage isn't as crowded as I thought. All I have is a car, a truck, and two GSXR's. My wife has a 600. Frank Mark H <landsail@...>...

I need some narative John. I'd like to know more on how the spring board plugs into the hull. I'd also like to know more about the front chock and the...

Dave, The spring board goes right down the center of the fuselage.I made a rectangular shaped box to fit the spring board. I cut all the bulkheads to receive...

Thanks John. Nifty idea to just slide the spring board into the hull. You won't even have to disconnect the steering cables ... which of course I'm sure...
