My thundercat

[Roflhat]

New Mako arrived a couple weeks ago, on the evening ferry on a Thursday then a hectic night getting it ready to leave first ferry on Friday. Weighed the old Ceasar which was a whopping 104kg. Mako is meant to be 77kg although not had a chance to weigh it yet. New Ceasar has arrived too so need to a do lot of testing soon.

Did 3 nights in Mallaig, got out to Eigg and Rhum with Douglas/Geoff W.

Up Loch Nevis another day, stunning area. Got to the Old Forge pub, most remote pub in mainland UK

No speed runs in the Mako yet but it's brilliant in the rough, handles the chop really well very comfortable and drier than any thundercat I've had previously

Currently working out of Carradale, on nightshift so some time in the days to get out and about in the nice weather

The water looks beautiful.

Ceasar arrived in October, still haven't been out in it. Very good looking boat though



Did some speed testing in the Mako in November, got upto around 57 knots but wasn't going flat out. Was half planning on returning to Coniston for records week 2023 but during the testing at home I was genuinely afraid. Never have been in a Thundercat before. Not the Makos fault I think I may just be done with trying to break records.
Going to keep my best props and things just in case I want to return to it later.

Also bought a 3.2m baby Thundercat, the idea being it can go on the roof of the car instead of a trailer. Will save a lot of money on fery travel, must have spent over £1000 on taking the boat to and from the mainland last year alone.
Got a nice 2021 Tohatsu 20hp four stroke to go on it, only 43kg. The boat itself is only 46kg.

Really enjoyed reading the last few posts on this thread, great pics too. Be interesting to hear how the car topper version works out.

Cheers, haven't been out in the little one it certainly is small! But should do for lochs and inshore. The Tohatsu seemingly uses 0.2 litres per mile, vs my Yamaha which is just over 0.8.

Made up some transom wheels for Piseag (gaelic for kitten, being a minicat), using a guide on Rib.net. Work very well, a bit tricky to do on a boat with an open transom but they fit


Got out for a spin on Loch Suainavat yesterday, a very deep freshwater loch just a few miles up the road. Boat goes alright, only the standard ali 10p prop on it at the moment but got a stainless 12p to test. Engine is very easy to live with, being 40 years more modern than my Yamaha 70ces and EFI which is nice!



Overall very happy, just need to make up proper roof bars to put the boat on the roof of the Subaru. Thinking a roofing ladder cut down to size so it has bunks like a thundercat trailer

Looking good, bet it's a lite pocket rocket.

Yeh will be a regular Thundercat I’ll use for that, challenging enough in a 4m never mind a 3m!

Ah yes I’m with you. Any photos of it? The newer model is the same as tohatsu I think, plenty information on modifying them.
Propellers are you biggest performance improvements, a good prop can transform the boat. What’s on there just now?

Stripped my Yamaha down again, the paint was really starting to fall apart. Going for powdercoat this time, in gloss black with some bits in red. Hopefully another carbon cowl in the works then maybe some custom graphics.

At powdercoating he found a crack in the swivel tube, just as well I got it done!
Crack welded up and a plate over the top of it. Need to get it all back together for Easdale

[Roflhat]

Got the engine parts back last Wednesday, spent all day Thursday putting it back together then down to Harris on Thursday evening to get the morning ferry. Very last minute but made it!

Fantastic weekend down at ERR 2024, 110 nautical miles covered on Saturday. Thick fog on Sunday so didn't go out but got a great day on Monday round the South coast of Mull to Balfours Bay.
Thundercat performed absolutely faultlessly

We also had a lovely time at Easdale we were there for a week and did the shorter route on the Saturday. Avoiding the sea plane in Jura was fun

Great photographs, what camera do you use?
