Some kayaks have areas to store stuff, but sometimes you want to bring more with you on a kayak trip. I thought it might be nice to have a small floating pod that drags behind your kayak, and holds the tent and other largish goodies. The pull-behind is shaped like a kayak but smaller, and a bit wider
(to prevent tipping), so it does not hugely affect the drag of the combined vehicle, simply adding storage space.
The opening in the top is a lockable water-tight lid, obviously.
Show me this already exists, and I'll delete the post (and also buy one). :)
Sweepers can kill you.

[napoleanbag] It sounds like you are a fellow kayaker. Have you ever tried towing with your kayak? It's a real drag. However, if you were leading a large-ish group for extended traveling, this would be nice. I would just hate to be the one who had to drag it behind. |
|
| |
If you have a tip-up rudder and a GPS, make a few runs rudder-up and rudder-down to compare the speed. You'll be very surprised. I found that when I was surfing the wake of large ships off Block Island that I couldn't surf with the rudder down, but quite nicely with the rudder up. |

ya I figure the drag is going to be a drag... I'll have to experiment with a homemade version... it's not ideal, but the tent and camping gear needs to get there somehow! There's got to be a way to make it sleek enough to cut through the water nicely... reduced drag... |
|
| |
btw... I've gotten in front of small waves on a lake, and it pushes awesome! I would love to know what it's like to surf kayak on the wake of a bigger ship... I'm still a rookie tho (2 years) so maybe someday when the opportunity arises... |
|

We do downriver canoe/dinghy/kayak trips sometimes <where extra resistance isn't such a big deal> - to date we've just packed ultra-light <and gambled on catching enough fish to eat well, not just "survive"> - I've often thought of making something like this. eg a 300-odd river-kilometer, 11 day trip earlier this year. Awesome. |
|
| |
To be frank, I had planned on just dragging one <or more> of those o-ring sealed plastic drums (~200litre) before - not exactly an ideal solution. a) fibreglassing is for sado-massochists, b) home carbon-fibre-epoxy kits are still very expensive, and c) I prefer poly (plastic) for all things river-going. This would be better. |

[Klaatu] - obviously you were assuming this was for sea-kayaks. Where I go, current is my friend - so the drag wouldn't be an issue. Maybe [napoleonbag] is thinking of river kayaking too. Maybe not. |
|

[Custardguts] If you are thinking of using this on a river, consider this: you have a large sweeper coming up ahead and you try to paddle to avoid. First scenario says you paddle to avoid, your trailer is pulled into the sweeper and the rescuers (body recovery specialists) have a nice picnic with all of the provisions you left behind. Second scenario has you back-paddling and your trailer pushes you into the sweeper. Again, picnic time with your provisions. |

I had an 18ft Aquaterra Chinook® and was able to pack for 2 week excursions without difficulty for both river and ocean. With a 700 lb. capacity, carrying enough supplies was never a problem. |
|
| |
[napoleonbag] If you take the waves at a 45° angle from the rear quarter, you can surf for miles. A real treat when you're paddling back from a long way out on Long Island sound. |
|
| |
I once made a kinetic kontraption out of my kayak and a bicycle, with a couple of five-gallon buckets for outriggers. It still hurts my arms to remember the hellacious extra drag. |
|
| |
A short, wide small kayakoid object is going to tow like a short, wide small kayak paddles--slow and slower. |
|
| |
It's a nice wish, but it's not a good idea. On flatwater it will be slow, on a river it will be a hazard. If you have some place where it will work for you, though, get a PokeBoat and try it as a trailer. |
|

There is a middleground between open sea kayaking, and whitewater river kayaking... and that middleground is daytripping lazy rivers and wilderness lakes which go for miles. These casual trips are more about distance and endurance than speed or adrenaline, so it may not be obvious to bigtime kayakers that a pull-behind pod may be helpful for smaller kayaks (9' or so) which do not have excessive storage space, and the additional drag tolerable, especially when a directional current or breeze is available. |
|
| |
Yes, it slows the kayak down a bit. Yes, there are huge 20' boats that make such a pod unnecessary. And yes, such a pod could kill you in whitewater rapids. This is a niche item not useful for everyone. |
|
| |
Think of it as one of those attachments for your bike, which can be used to pull things (like kids). Yes, it slows the rider down, but people still use them, because they are helpful in certain situations. You just see them in triathalons or mountain biking expeditions (usually). |
|
| |
[Custardguts]... I was thinking of making one from fiber/epoxy, but yes, they're spendy! I wonder if there's a streamlined children's watertoy on the market that could be adapted into a pull-behind pod? |
|
| |
the niggling part of my brain says you want it in front of you so it would probably have to be fixed'ish instead of free-wheeling... so a foot-pedal assembly to manuever your new "front rudder" |
|

[Klaatu] - no sweepers whatsoever in this river. We spent more time hanging off the front of our boats swinging an axe to get through close foliage, than we did avoiding any of the 5 discrete sets of rapids <which, in a decent kayak, you wouldn't even have noticed anyhow - I only call them rapids for want of a better word>. I'm well aware of the hazards - but I don't embark on a trip like that without knowing what the river has in store. Yes, my take on this is more about compensating for not having the storage space of a very large expedition canoe rather than anything else. Trip goal was more about seeing the river, catching masses of barramundi, and offing the occasional feral pig rather than negotiating white water. |
|
| |
The other thing is they could be short-tied maybe <500mm from your boat. |
|
| |
So I vote for the floating extra storage. |
|
| |
There are time I've wanted something like this. I think inflatable would be nice.
Then when you find the mermaid on the beach, instead of trying to stow her in your kayak, you could inflate this and strap her to it. |
|
| |
I know, I know, drag, drag, but in the end you've got a mermaid. |

Actually, moldless foam composite construction <link> would not be that expensive, would be light and would have built-in flotation capabilities. |
|
| |
Because of square-to-cube ratios fo surface area, it's probably going to be better to opt for making the kayak a little bigger, thus giving it the requisite storage space, which won't increase drag that much if the geometry is preserved. |
|
| |
The idea of using a highly buoyant inflatable with minimal immersion and no keel is going to cut drag, but it's going to be very vulnerable to winds. |
