That is my favorite boat.
Have one of Chris Fine's builds with an 11HP in it.
Super fun boat....
I have had that boat out in some 3 foot waves and it takes it.

Hi Fred
Are you running endurance races? What set up do you have in the boat?

[fred 75]

Hi Peter,
Yes...My set up is : TP 4070-440kv ( real kv is 460- 0 timing), Hobbywing 130 HV V3- X457- 12S 16000 mah-COG: 32 %.

Hi Fred
Great to see more electrics doing endurance. I have been running an Osprey this year,
https://forums.offshoreelectrics.com...Endurance-Boat.

I would have been keen on a Challenger 43, but it is just too difficult and pricey to get down under. I have a 46" boat for next year running a Leo 5692 540 kv on 10s, same esc, 20AH packs. I may change over to 12s later as the 20AH packs seem to have become unavailium.
What prop(s) are you running and what sort of speeds are you doing?
Any chance of some pics of your set up?

I really enjoy the endurance racing, especially when you just keep going round without the gas issues. There can always be other problems at times though. I have been taken out several times by gassers and their bad driving!

I read your thread...The prop is an X457. Top speed is 72 Km/h with Multistars...Run Time: 21 to 23 mn. I Really like endurance Racing too...In France, it’s quite different : most of the gassers accept Electric boats...No problem...and some of them also have fun with electric boats...it’s effective for example in my club (Viry).

Nice. How do you hold your batts in? Do they just have velcro to hold them to the hull? How do you seal your hatch, tape? My top speeds have been in the region of 70kph. In rough water you cannot use it so well, if you want to stay upright that is. I like the rough because it slows the gassers down, some of them here put in ridiculous horsepower and have boats of 65"+ in length. It does show though at times with reliability issues.
It has been great this year proving that electric can do endurance racing. I am hoping that there might be one or two more take it on.

Hi Peter,
I only use Velcro to hold My batts In...But i’m not an exemple...too lazy and it’s hard for me to finish a boat......with the Weight and the dimensions of the 6S 16000, and a good Velcro, it’s ok for me...No particular issue... to seal the hatch, I’m using a large tape at the rear of the Hull...and I use a sheet of polycarbonate (lexan) under the hatch...Four races this year with the Challenger...and a first participation In the 24H of Viry, as member of the winning team...Great fun...A Great Way to learn about endurance boats...
