"Nose Wheel" for Boat Dolly?
Last year I got rid of my windsurfing gear and got something called a
"Hobie Adventure Island": basically a kayak with outriggers optimized for sailing. About 220# beach-ready. Hobie sells a set of beach wheels that work fairly well: https://picasaweb.google.com/1081497...48948995878306 https://picasaweb.google.com/1081497...48951297106850 https://picasaweb.google.com/1081497...48949117328978 https://picasaweb.google.com/1081497...71011817870194 But the holes they mount into are so far back that the nose becomes about a 50# lift. Not un-doable by any means, but it's not what I would call easy on the back - and it has it's problems when a slope has to be negotiated and something closer to the boat's balance point would be a beeeeeg improvement. To that end, I've been fooling around with a frame that holds the boat, slides on-and-off the trailer, and has beach wheels mounted on it, but it is flying in the face of the KISS principle and it seems like embracing the existing wheels is the sensible thing to do. That being the case, I started off thinking about a pack wheel/game cart (as in https://youtu.be/4-gt-VF0zEI?list=PL76069A6D971DF3F9) but, once again, I think I am going overboard on the complexity - not to mention the price The Bottom Line: Can anybody think of something off-the-shelf that could function as a "Nose Wheel" for this thing? -- Pete Cresswell |

How about some pipe fitted into the intended holes -- but, swept forward (to the balance point) to a cross member on which the beach wheels are actually mounted? A risk, here, is the stresses that would be placed on the "holes" would differ from what they were designed to expect. I assume this would crack some bit of plastic (?)

To be clear, you're thinking of making a tricycle out of the thing? Can you leave the existing wheels "plugged into" the holes (that are too far astern). Then, make a fork that clips onto the cross member of those wheels and extends forward to a point at which a "pivoting wheel" is mounted. I.e., the fork is triangular in shape (like an old wooden "crutch"). At the tip, a pivoting beach wheel is mounted facing downwards. On the *top* surface of that point, a carpetted pad insulates the fork from the underside of the boat. (The boat *rests* on this tip of the fork with the pivot wheel beneath). On level surfaces, the boat sits "flat" on the trike and is pulled along (perhaps a rope that straddles the boat at the front wheel and connects to that wheel -- this allows you to tug on the wheel and, indirectly, the rear wheels as well as holding the wheel *up* against the underside of the boat). If you lift the front of the boat, the wheel can come up with it turning the boat+wheels into a sort of handtruck (dolly) that you are dragging along behind you. You might be able to experiment with SCH 40 PVC as a cheap frame (for this "fork"). Or, EMT (or even RMC) Idea for wheel pivot: https://ldvbeachservice.com/ldv-assets/uploads/2015/02/Beach-Wheel-Chair-Rentals-Destin-300x200.jpg Could you also use a (wide) "ski" in the front? |

Maybe a combination of these would work: 1 - What about building a "hinged clamp" that locks around the hull at your desired wheel location? Basically a supersized version of this: https://cdn.mscdirect.com/global/ima...0452268-23.jpg If built so that it's foam-lined interior surface "mirrors" the shape of the hull, almost like a mold, it would clamp down tight and not slide forward or back when in use. 2 - How about a frame that mounts in the existing holes but with the wheels mounted forward of where they are now? Hull Holes |_______Wheels The frame could be secured to the hull with ratchet straps at the mounting holes and near the wheels to keep it firmly attached. |

Per Don Y:
A risk, here, is the stresses that would be placed on the "holes" would differ from what they were designed to expect. I assume this would crack some bit of plastic (?) Good catch.... I put something like that to a Hobie rep a few weeks ago and his reply contained the phrase "...think breaker bar...." so I dropped the idea of messing with anything that goes into those holes.... the downside is just too severe. Then, make a fork that clips onto the cross member of those wheels and extends forward to a point at which a "pivoting wheel" is mounted. I.e., the fork is triangular in shape (like an old wooden "crutch"). At the tip, a pivoting beach wheel is mounted facing downwards. That is pretty much what I had in mind - but was looking for some off-the-shelf source for the pivoting wheel. -- Pete Cresswell |

Start with DerbyDads idea of something that mirrors the shape of the boat. Use somthing like this http://www.northerntool.com/images/product/2000x2000/446/44659_2000x2000.jpg to wheel it around?
