Personally I have gone about 49.9knots. could not get the 50, scary it was too.
A guy who ,when he went to do his VHF course and the instructor asked them how fast any of them had been on a boat and his reply was 600 mile an hour, not sure the instructor believed him, he does in fact holds the record .

65/67 knots on a SBS craft (as per my avatar) which I used to maintain and repair, it was a boat that was designed and built by the late Fabio Butzzi basically a racing boat.

Had a 19ft open aluminium boat with a rib style long seat in the centre and a 200hp v6 2t yamaha on the back.
Acceleration felt like it was on par with a motorbike , it was really hard to hold on while accelerating and in absolute flat calm I touched 70 knts ,I'm sure it had more, but I didn't !
Could do marine power wheelys on demand. Terrified passengers due to acceleration.
Terrified me being capable of drinking 25 litres in 5 mins .
Next fastest vessel I've been on is probably the Sr n4 hovercraft, although that thing went some 89knts on its last journey so a retired pilot told me.
The current record is 318 mph set back in 1978. Will it ever be beaten as an extremely high risk of death attempting that.
I will apologise in advance for mentioning a wind powered vessel but hydroptere, a 60ft trimaran reached 56 knts !

On a jet ski was probably the fastest but no means of saying how fast so will go for 40 knots on acceptance trials of a Redbay 12m cabin RIB with Hamilton jets. A very capable boat so not at all nerve wracking 🙂

Sorry I had to correct you slightly, not being pedantic at all, MapisM would not approve of spelling his name wrong. ;) That is one nice looking boat, off to search it now! :cool:(y)

The "scary" bit doesn't depend just on speed, but also on the boat and conditions.

I've yet to find out how fast the tender of my current boat can be, 'cause it's a 9' RIB with a tiller driven 15hp 2T outboard, and it's a handful already at 20kts or so, even in dead calm waters.
But my old Fountain 27 Fever with the stock 496ho could reach 72mph when lightly loaded, and was rock solid also when Lake Como was choppy, never scaring anyone onboard.
Otoh, a chap who used to have the very same boat with a spiced engine (600hp or so) did manage to scare my wife a bit, when he engaged (and won!) a sort of race in San Diego bay with a US Customs Midnight Express, at 80+ mph.

Anywyay, my personal answer to your question has got to be I don't know.
In fact, many years ago, a friend of mine invited me to try his custom 21' air entrapment catamaran, powered by the epic Merc 2.5 EFI.
He asked me to keep her straight while he took care of the throttle, and off we went.
I was petrified enough to not say anything on the intercom for a few minutes, my only concern being to hold the wheel as firmly as I could.
But after taking off on a small (surely less than 1 foot) navigation wake which I didn't even see, I politely suggested him (i.e. screamed) to slow down.
Ref. speed, the pitot speedo pickup was dirty, hence useless.
But the owner of that little monster regularly makes 120 mph with it, and according to him, even if that day we didn't go anywhere near, we surely ran into 3 digits speed.
And yes, THAT ride was scary. Every second of it.

72 ish knots on a 36ft donzi, about 60 ish on hunton xrs 37
Did 70 mph in a 16' Donzi with a 235 HP outboard. Was a bit scary doing that on really calm, flat water as over 60 there was so little of the hull in the water it would start chine walking.

I wasn't onboard but my sailboat went 70 mph when I had it hauled down the highway on a trailer.

47 Knots in my Fletcher 19 bow rider with a 200 hp V6 on the back. It would have gone faster but it got scary so I pulled the stick back
