I'd like to update my thread after 5 months of saying nothing. I think there must be someone out there who's at least a little interested because...
My paddlewheel propelled pedal boat ground to a halt in a mat of weed on the canal. Whilst the paddlewheel was OK, the rudder got stuck. A wheel...
After several more tests with the catamaran, I'm happy. I've been improving chain retention and adjusting the paddlewheel height and, hence, depth...
Not yet perfect but I'm getting there! I had a much better time on the canal, today. I have a couple of modifications to make but now think that I...
A quick update on my progress. I tested my front mounted paddlewheel yesterday and averaged only 1.9 mph. The problem seems to be too little...
There is not enough room between my hulls to make the paddles sufficiently large so the first system has had to go. Instead I'm building a front...
I've just calculated that the wetted area of my catamaran hulls is around 10% greater than that of my dinghy, which could reach hull speed and...
My shorter dinghy had a completely flat transom and no rocker but could still cruise at 2.9 mph from a hull speed of 4.16 mph. What I noticed with...
I've done it! I've splashed my new boat. All seemed well except for a lack of propulsive force. I need much wider paddles and have planned the...
Tomorrow may be the day for a first launch of my new boat. Exciting! Also worrying. All sorts could go wrong. Close to launching my new boat....
I've laid the components out and it might even have started to look like a boat! I only need to do some painting, a few small bits and accurately...
Waterproof PVA like Titebond 3 might do the trick. Although it claims not to be suitable for continuous immersion, anecdotally it works. It is...
I'm progressing with my build and hope to be ready to test by the end of this Month (April). Boat building progress....
My pedal powered dinghy was built from 1.2 mm Al. I wouldn't try to weld anything as thin as this but in my case I didn't need to. How are you...
150 watts is easy enough for one hour.
Yes. The mechanism works in the same way. I've made mine taller to keep the paddles more upright, entering the water around 30 degrees from...
It isn't a great photo but this is my half built pedal mechanism. The pedals so far are 12 mm rods which are each attached to the lower sections...
Just for fun, here's a picture of a Tuggy sandbox, many of which have been turned into boats. Log into Facebook | Facebook...
I've managed to do a bit more work on the frames which will link the 4 hull sections together. Here is one resting on 2 hull sections and leaving...
4-6 Kw from an average E bike battery will drain the battery in 15 minuted. Except that you can't draw that kind of ampage in the first place....
