Innovation in Plate Hull Design 2

[Briz]

Around a year ago I posted a thread on “Innovation in Plate Hull Design” along with some pictures of the boat I was building with an old school friend.

There’s been a bit of progress since then … finished building towards the end of last year – then several months while I painted it myself under our house – and a few more to fit it out (bloody thing called work kept getting in the road). It finally tasted water last week on its first sea-trial – few more small jobs to go but very happy with the project & end result!

Here are a few pics of the journey from arriving home – ground and sand-blasted; building a spray booth under my house; etching-bogging-faring & coving & finally it gets a drink! As others have shown on this site – there’s no single formula to getting your own platey just the way you want it!

Now that is a very well finished boat. How did you get the nice flowing effect with no gunnel capping. It’s that nice you almost think it’s a glass boat, well done on a magnificent job.

An excellent display of workmanship and design Briz. A real credit to you.

How did the extra depth of the keel perform heading into the waves?

What weight did your hull end up and what are the basic dimensions as built?

Tassie Jr – it’s a 70HP on the back – we kind of designed it to get up early and hopefully cruse at low rpm– which it does at just under 4000 (smiles all round on this one) – my Scottish heritage made fuel a major design factor before we started!

Stu – one of the main themes of the whole thing was to try and not have a sharp (i.e., 90 degrees) edge anywhere on whole boat – lots of work but it was worth it in the end. You would be amazed at comments from several people so far who’ve tapped the sides and asked how we got the fiberglass to stick to the ally!

Jack – the final length ended up at 5.2 – but given the design underneath the hull seems to hold its length on the water – lots of fun playing around in the wake of one of the ferries (kept out of their way) – no bad habits so far to report – to be honest it’s the smoothest thing I’ve been in so far (but then my opinion would be discounted as potentially biased!) – as for weight I’d be guessing at an exact figure but we are going overboard on the flotation foam (suppose I need to run it over a weigh bridge somewhere).

Great job Briz

I have a few questions for you,,,what does it weigh with gear and fuel and what speed/revs do you get accross the range? and what is your waterline length and beem?

Thanks

Hi ifishhcq - didn't have the gps fitted for the first test - all I can honestly tell you at this stage is it planes at about 3400 rpm, cruises comfortably at 4000 rpm - it's powered by a 70 hp four stroke which peaked out at 5600 rpm on test day. Sorry I just don't have any more concrete data & I'd be speaking out of somewhere nasty if I said too much more without the facts - can provide more info at next water test fully fitted out loaded.

I'm not big on plate boats, but yours I really like. Add to that you built it yourself, and it is one off the nices platies I have seen.... 10/10

Well done

Now I'm jealous ! Great job

Awesome job. Im lost for words how nice that is. Can we see more pics please.

Im always thinking of a next project and something like this could be on the cards, in quite a few years though. Never too early to dream though.

Thanks Jabba, Frank100 & Lancair – should set the record straight - didn’t build it 100% by myself although I’m going to add this photo just o get my mate 'worked up' (me doing some tacking … you know “The boat briz built”) … but to say I built it would be totally wrong as although I might have cut a lot of plate and tacked it in – the boat was Brian’s design (top and under-the water-line) and Brian who did all the final welds - my input was more along the lines of what I wanted and where I wanted this or that - I suppose a form of hands-on customizing where you ended up doing the actual work (joke still is I always seemed have to do the hardest parts – sense of humour helps in a project between mates) – but hard as it is to say (as long as he’s not listening) the bloke's a true professional so I should tone-down the jokes as the project's not 100% over yet!
cheers

Fantastic looking boat with some unusual design. Some other questions are what size fuel tank did you put in and what sort of compartments does she have.

We will all need a good pair of sunnies on when you come by.

o'h too be so clever , i wish , very nice

beautiful boat mate.. would also love to see some more pics, in particular the cabin!

You have to be happy with the way it turned out!

[Chamelion]

So, how is this boat going? Have you had it out in less than pleasant weather? I'm interested to know how it went. Hows about top speed?
