Sabotini / bicycle trailer

Postby Jth1968 » Fri Jun 26, 2015 8:21 pm

I’m nearing completion on a Glenn-L Sabotini dinghy/ bicycle trailer. I need something I can pull behind my bicycle six miles to a local lake where I have a Catalina 22 on a mooring. Parking is huge hassle and the roads close to the lake have no parking after 10pm. I came up with the idea of using a removable towbar and bike trailer wheels attached to an aluminum axle that runs under the center thwart. I bought a bike trailer kit from http://www.wicycle.com/index.php/produc ... le-trailer
The hubs have a button in the middle that allows the wheels to pop off when I reach the lake.

I originally wanted to build in glued lapstrake. I was particularly smitten with Oughtred’s Auk. After looking over the study plans I realized that a slab sided pram would allow the wheels to sit closer to the hull as well make the towbar attachment easier. My other issue is I really need to keep weight to minimum. I’m familiar with El Toro’s and the Sabotini has nearly identical hull shape so I’m fairly sure I’m goin to be happy with performance.

My Sabotini is constructed with 4mm okoume and Spanish Cedar. The thwarts are constructed from a sandwich of 3mm and Nidacore honeycomb which I laminated with epoxy in a vacuum bag. I had epoxy left over from other projects so the inside is coated and glued with West System and the outside and Spanish cedar is System Three.

I was really hoping to keep the weight minus wheels at around 40 pounds but at the moment, finished with exception of paint and varnish, it comes in at 45.

Paint comes next Tuesday so I’m excited to finish sanding and get it in the spray booth.

Genius idea!

Hey - How about adding a chainset & side paddles to swap out for the wheels! :lol:

It’s funny that you mention that because for a quick bit I thought about building an amphibious canoe. Something like, http://www.autocanoe.com The thing is every pedal paddle wheel thing I’ve ever been on I’ve hated. Slow and splashy and crazy ineffective. I think I would have ended up with a terrible canoe and an even worse bike.

My Sabotini will perform in the water just as well as any other pram. And I’ve done tow tests with my dinghy and it tows great. Headwinds might be a bit of a problem but otherwise I don’t notice it’s there. Here’s a video I shot in the warehouse connected to my shop when I mocked up the tow bar to test alignment.

Ha ha - This guy over here in the UK said the same thing - Pick the thing you want it to do well & compromise on the other, rather than make it bad at both.

I think you went the right way.

... Still... projects for the future eh? :lol:
