And don’t keep it in customs a day longer than necessary, as you get charged £100 a day, don’t ask how we know that [emoji15][emoji15]

They are rated for 70hp, go for 40hp minimum, any less and you’re wasting your time and you would be as well with a Honwave, Aerotec etc etc plus it would save the hassle of importing.

I think it has 5 chambers

[Bren2103]

Cheers m8 ,Definitely no less than a 40 for me

I have one of these here in Australia with a 25 Yamaha fourstroke. Fantastic.

Only issue is Ive had both the handle ropes pull out of the back pontoons near the transom. Likely as a result of the very hot weather we've been having ( +46 deg C) . Expect to get a bit wet in these.

Ive got the GRX 420 here in Australia. Great boat with a 25 yamaha fourstroke.
The tube ropes pulled out at the back near the transom. likely as a result of super hot weather ( +45 deg C). Now have to figure out how to get them back in.

Got any pictures to post up? Always interesting to see other setups?

How old is yours?

Hi Rob, do you still have this. What kind of speeds did you end up with one forsale locally to me and a surfcat. Deciding on which one to go for.

[ThundercatRob]

Hi, yes I still own it.

I was out on it last weekend. It’s a great boat, very well built and fast. It’s the acceleration that’s the main standout and the way it pops out of the holel. Planes at low speed as well. I think it’s around 8 knots.

I’m getting about 30 knots out of it, however i still think the engine could go a little higher, but I’m not chasing speed so not too bothered. It’s plenty last enough and feels as fast as my old Thundercat (however I never actually measured that)

My GRX is heavier though as it’s made from Hypalon and I also end up carrying loads of stuff in the bow bag, which probably means it’s not trimmed well for speed!

Great boats, I actually wish I owned it over my Thundercat all the years ago as it’s so much more versatile (any surfcat would be the same as this)

I am however thinking of swapping to a RIB as I now have a young family and it’s not that suitable. Having said that, I went out with my 2.5 year old daughter and wife at the weekend and they all loved it.

Thank you for taking the time to answer. What's the value of these second hand looking at them they're unique in the UK.. so guessing what someone is prepared to pay.

[ThundercatRob]

Yes I guess so. They rarely come up for sale, so hard to judge the value.

I would want £4k for mine to sell it as a package with trailer etc (mine had a brand new trailer in I think 2020, which was about 2k on its own.) I did get a price for a new one with M50D2 motor and it was about 15k all in for a full setup, but that was a few years back, so probably more now with inflation.
