Thread: Building a boat

Hull marine have some good kits that come cnc cut and folded for you, there will be a few around that do them tho, it’s fun building your own, sounds like you’ll have no problems with all the gear

I'm going ahead with the build. priced the material. Been mocking up some pontoon shapes and thinking how the hull will go together and how everything will fit in. Let the fun begin

I have only just seen this thread,there were a number of companies doing 'Flat Pack' boat building kits & detailed DIY plans/designs in OZ during the mining boom, years ago as the normal boat manufacturers could not keep up with demand.I do not know if you have researched over there or whether those companies are still going but may be worth a look for ideas & methods of easing construction .

A number l know of up in the top of WA were basically what you are looking at ,they have to do beach launches so they were 5-7 mtr pontoon boats designed to be beached to unload etc .

Good luck with the build & make sure you take plenty of Pics & post keep us updated ,l love it when blokes have a crack at things like this

I would be doing plenty of homework on pontoon shape vs hull pounding and effects of chines if you get it wrong you could end up with a hull that pounds badly.....

Very very basisicly and over simplifying.
You need a decent chine in the rear 1/2-2/3rds hull lenght...the bottom of your pontoon is your chine in a pontoon boat, it is generally a reverse chine to varying degrees rather than flat to give cornering hold and spray turn down.
Big exposed chine at the stearn and less at the bow to reduce the slam of water hitting that big flat chine forward.

Quick look at a few boat shops will show what I am on about tho Id say if you're already committed you have a plan to suit your use already.

Playing with this idea of the rear end. Trying to follow how other boats of the same size have.

doesn't leave a lot of space between the pontoons, very cosy for 2 people dealing with fish.

Yes I realised after drawing out on the floor I have adjusted the inside width to 1500. Will still cosey but most of the time itl be just me so I'm ok with that.
