Also with the wheels closer to the hull it lowers the center of gravity also, less chance of tipping.
Swing scupper cart....Mk 2
After playing with the original scupper doctored SuperCheap trolley decided to update to a lighter version from lessons learned on Monstrosity 1
Bought a couple of lengths of 13mm box section aluminium for uprights, with plastic tube to cover and protect in scuppers..cross members are 50mm x 25mm angle alum... and a handful of 25mm x 4mm metal thread bolts....outlay $10
Bolted together as shown in the pic, and attached the SuperCheap trolley axle and wheels...this was an improvement, but the wheel assembly still made a bit heavy.
After lunch found an old set of golf buggy wheels under the bench, and replaced the pumped up tyre wheels to make a much lighter version.
This is not a fold up model but thats not needed for my use, the axle could be raised 90mm closer to the swing, but I prefer the extra ground clearance for the yak and the wide wheelbase is nice and stable. .... [note changed my views in final version]
The bottom three pics are related to this original topic, while the top pic is the final version
EDIT in 2011 ......Final modification done in 2007 and still OK in 2011 and has covered some really rough launch sites at times and not the slightest sign of damage at the scuppers .... the frame was altered to only one cross bar, and this lowered the centre of gravity even more, and some green paint was daubed all over to make rough camouflage as I only throw the cart in the bush while on the water and rarely take it on the yak, if I do it is carried 'Hobie' style upside down in the rear well
