First of all, if you don't know what a proa is than let me explain in short.
It's a multihull type boat. It looks like an asymmetrical catamaran because one hull is bigger than the other one and the mast is clearly out of center.
This is because the proa moves differently than a catamaran. It's a bit of a hybrid where there's only one hull who's always in the water while the other hull balances the forces of the wind.
This however makes for an interesting problem when you want to sail upwind. The way the proa keeps it ama (the windward hull) stay on the windward side is by shunting instead of tacking. A very different approach then you're used to seeing. This way the boat has no actual bow since it will sail in both directions.
Still don't understand?
Google ''shunting''
or watch my video explaining it in detail and comparing tacking and shunting:
I've been welding and grinding since october and now the ama is actually starting to look boatshaped.
Even better... It's mostly waterproof on the first pass of welding!
Check some other pics in the attachments!
It's been a blast making it and it's honestly a blast sharing the whole process.
So many questions still to be answered but so much fun already had!
I'm also keeping video updates on my youtube channel (king herog) since the beginning so I'm documenting it pretty well.
Here's my latest vid:
After a while I'll have some useful insights in welding aluminum for beginners so watch for a video about that.
Also to be found on instagram under the same name.
Following ideas I'd like to put in practice on this boat as a reference of what kind of project this is going to be:
2 wind generators of 400watts nominal power each
around 1000watts of solar panels
electric outboard engine
long term storage akas to make the boat a whole lott smaller and thus cheaper to store in a marina.
a autohelm autopilot combined with a raspberry pi opencpn plotter with a motessier hat on it to combine it into a full on autopilot.
casting my own kickers and other sail hardware
2 oak bowsprit sculptures by a friend
and plenty of other normal sailboat equipment
Wish me luck!
But I'm already having fun!
