First try today, it’s a crazy how the hull has a better behaviour than my boogie.
Pivot like a zero tow, so smooth, even with lot of throttle no capsizing.
Not to much nose up on take off even with no tow bar
This Dinghy Tow is a real Game changer !!!
Propellers distance center to center 21cm
Propellers center distance to waterline 17cm
Looks great! Made me think that maybe the Lift foils efoil attachment ($600) could be used to create a variation on this. Would need to build the hull, which seems likely to be the critical part of the performance
I thought about this one previously. The best alternative to my dinghy in my opinion is Spearfishing boats in PVC or hypalon. You can find also old kneeboards.
Great find, thanks! I quite like the look of this rigid PVC Wettie Float Boat, or this inflatable Pegasub (they look a bit unlikely to handle speed very well)
Filling mast with electrical gel to waterproof gong V3 masts. Top of mast are under waterline.
Stuck the dust protector of amphenol connectors inside the boat to carry it properly
Set a waterproof yellow bag to carry rope and handle + possibility to ballast sea water easily if it’s choppy.
Made a sock to add another water barrier to the non return valve, works like a charm
Next projects: onboard wheels and a cover to avoid waterspray coming in !
I tested to turn with one motor only, compared to my boogie design. Without the extension bar and despite having reduced the distance between pods from 27cm to 21cm, the tow dinghy turns on a dime, the radius is around 5/7 meters I’d say
The Alu hull is nice, but doesn’t add massive advantage. Its the outer inflatable section that prevents rolling. The nice thing about the inflatable outer that I posted is that it gives you the option to use a V or flat bottom and also choose a material that you would like. Its a good source for DIY. It probably should be posted more in the general section instead of in this build though.
My thoughts on this is that you could make a hull out of eps or xps and laminate it and then cut part of the pvc bridging the inflatables ribs and leave some overhang and glue the ribs to your hull.
