Finally I was able to test it on the water
Couldn't find a suitable river nearby so opted for a local park
Very pleased with the results very stable on the water and quite fast even though I kept the revs at about 50% until fully run in
Hope you all like it

Six months ago I drew up the plans for my Jet Sprint boat and at last it is completed and ready for its first test run
Very happy with results so far so hope it performs well on the water
Have leak and ballast tested it and all good so here's hoping for a successful first run up the river
Has been a real challenge at times but well worth it and a lot of satisfaction and fun making it
I have named it "Rapid Hoppa " so I hope you all like it
Will post a video of its on the water performance as soon as I can

By the time I fit the roll bars and seat together with 1/4 scale driver it will look a bit different
Plenty of grunt as it develops 3.25 hp

Hi Wayne
Can't have that lol
Fitted engine and currently wiring up all the controls
Has taken a bit longer than I thought because of my other projects like finishing Sovereign of the Seas and preparing RC Beaver for flight oh and trying to get a bit of oil painting finished off
Who says retirement is boring lol
I just keep running out of time not enough hours in the day
We have a national model boat show on over labour weekend in October so I hope to have the jet finished by then but have to do some R and M on the Corvette and Amara tug steam engines before then as well
Have posted latest pictures
Cheers

Hi Dave
Yea we have the same rules down under with not being able to use petrol powered boats on local lakes but this one will be used on smallish river rapids so well away fro the locals
Be a while yet before I get to test it
Much to do to complete the model

Well finally finished the actual boat and now ready for fit out
Zenoah 26 cc marine engine arrived this morning and jet unit on its way so busy days ahead
Got to make roll bars to scale yet probably use aluminium to save weight
The engine develops 3.4 hp at 13000 revs so should give it a bit of punch
1/4 scale crew to order yet and some instruments for dash board
Think I will have a wee break from it all for a while and give my mancave/ Messcave a bit of a tidy up lol

First coat of paint is applied Very pleased with result
Kawasaki green so I can spot it on the water easier
Think I will name it Kermit and paint him on it somewhere
What do you think ?

๐ฌ Top and hull come together

Thanks Wayne
I'm enjoying making this one up from scratch more satisfying I must say but fairly challenging and slower than kitsets that's for real !!
Heaps of sanding ahead of me but worth it to get a good paint finish (I hope )

Just fibteglassed the top and hull together and tried the rubber bumper strip out for scale
Looks like it will do the trick
Now onto a heap of sanding sanding and more sanding to get it perfect for painting
Still not sure what colour I will use but I guess something that stands out amongst the river rapids

Hi Wayne
This boat is being made for going up river rapids through boulders etc so it will be getting somewhat knocked around so I would be happy if it only receives a few scratches lol
I take you point though but I havn't purchased the running gear yet
Can't quite make my mind up on battery power or petrol engine
I've got a bit of time yet to make a decision
Cheers
Rod

Hi Dave
Unfortunately the silicone system did not work so I reverted to what I normally do and that is casting plaster and it has worked out nicely After I finished the mould I painted the plaster with etching quick drying paint and then coated it with petroleum jelly as a release agent
The top popped out of the mould beautifully
I have found a rubber bumper strip to use on the joint so should look pretty realistic
Cheers

Hi Dave
It's been a bit of a mission that's for sure with some trials and errors but with determination we made it
Will spend a good deal of time on the finish of the hull and top to get a really nice paint job and then onto the fittings

Hi Dave
Your right there I intend to slope the sides ever so slightly with clay attached to the sides of the balsa wood as this will enable easier seperation of the mould
Thanks for your continued interest in the project
Looking forward to putting it all together eventually

Removed first hull from mould
Had a few problems with the release but all OK now so onwards and upwards !!
Laid profile for top deck now and starting the clay shaping
Should be a bit easier than the hull and hope to have this ready for moulding shortly
I intend to cover it with silicone first to get a good impression and back it up for strength with fibreglass strengthened casting plaster
I will then lay the fibreglass in the mould and gradually build it up for the finished article
Well that's the theory at this stage lol
Will keep in touch with progress but going well and I am happy with the results so far

Thanks for the info
We are well on the way to sorting it out now thanks
The guy that did the original take from the mould used gell coat which I didn't want as it chips too easy on the river rocks and I don't think he used the correct release agent either
However all good now and should have a new one off shortly
I have commenced the top half now and will use a silicone mould strengthened with fibreglass and plaster over the back of it to hold in place
I have done this before and should have done again on the original mould
Slow learner aye !! Lol
It is going to look just fine when it is all finished
Will post a photo of it when the next hull comes off
Cheers
