Hull length of a Futura Mark 3

Hi,

I am try to find a trailer for the mark 3. I know the overall length is 4.5m but do you know what the length is from the engine mount to the tip bow? It looks like the tubes go ~0.5m past the engine mount. Would the hull length them be 4m?

thanks,

Measuring from top of transom to the tip of the bow, 4m exactly, mate.

Sharkbyte,

Where on the bottom do the trailer bunks support the SIB? Is it the point where the bottom meets the tubes?

I am tring to figure out how far apart the bunks need to be to properly support it.

thanks,

Hi skoskii

I built my own trailer specifically for the Mk3, so I'm not sure how helpful my info will be.

The tubes are directly supported by bunks that tilt slightly inboard. The keel is supported by two additional bunks in a fairly tight v configuration. The keel bunks slot between the speed tubes so that it automatically centers the boat up even on a choppy beach retrieve.

It took me quite a lot of trial and error to get the bunk heights and angles right. The boat was probably on and off that trailer a dozen times before finally welding the mounts on.....and the only time I have used the transom wheels lol. If you would like any angles / measurements, just give me a shout.

It's well worth the effort in getting it spot on. You tend to see quite a few trailered SIBs with kinks and bows in them after they have lived on a badly fitting trailer for a while.





I knew I had a photo somewhere....hopefully my ramblings make a little more sense now.

Thanks skoskii

It certainly does it's job admirably, and was well worth the effort.

Cost about 400 all in, including galvanising, which saved a good few quid too!
