I do not mind sleeping with a layer of salt on my body and actually prefer to do the washing up in a bucket in the well than wasting fresh water in a sink.

Once the weight starts to increase it makes sense to increase length if you still want efficient operation up around 8kts. The alternative is to accept a lower speed.

If you want to continue along this line then maybe start your own thread setting out the requirements with a total weight estimate of all the "luxury" items and live load.

Sorry if I've gotten carried away and hijacked this into OT. I felt the Tri-Faux is so close to my potential spec that a separate thread might be premature until I develop a good enough understanding of "things naval" to formulate at least a semi-intelligent and somewhat feasible brief.

As for comfort I am all with you on your spartan thinking, hence I assume a very similar fitout spec. Fortunately, Her Ladyship would not mind a very basic setup. I am living evidence that She has very low basic requirements indeed...

If I ever move beyond daydreaming, I will set up a separate thread. Anyway, I am likely to begin with an "excercise craft", closely inspired by your pedalboats, before moving on to something more ambitious.

It is an inexpensive means of learning about hull drag while shedding weight. More enjoyable than other forms of exercise particularly if you have a nice body of water nearby. My V14 hull is getting its finishing touches right now. The hull is 9.9kg but is still to be faired and painted so will gain another kilo or so I expect.

Got the Baltic Sea in the front garden. I guess the Baltic will be a bit too rough for such an extreme boat as yours.

Is there a thread with more info on this latest iteration?

Rick, I'm impressed. I've built 6-foot tow test models that weigh more than that empty. You're talking about something that can carry a man.

KalleA- for the Baltic, you'll probably be thinking of something a bit more substantial than Rick's pedalboats (he's posted a few photos around here- they look way cool, but are rather lightly built). It shouldn't be too difficult to extend the concept to a slightly more robust craft. And it would be a lot of fun!

I've been admiring Rick's pedalboats for some time now, and I've also been following Greg K's pedal-the-ocean boat. Great stuff. I would need something inbetween the two for pedalling along the Baltic coastline, I believe.

I will post build and final photos on the Pedal Boat thread when finished. The attached shows the linesplan and the hull formed up without the deck.

As always the hull is not perfect but I am happy with it. It comprises 200gsm bi-axial CF cloth over 3mm klegecell. It does not take many man hours to build this sort of hull but waiting for epoxy to cure in cold weather means it takes time. I waited till April to start because it was too hot before then and now it is getting very cold. I need heating in the garage if I was doing this stuff seriously.

Looking forward to following this. Amazing how light the thing is.

Cheers

P.S. I have taken your advice and opened a separate thread:
