how to beef up my chimes ????????

[bobbyb]

what would be the best way to make my boat more stable at rest and not have to boss every body around as to where to stand and dint all run to one side of the boat it's plate ally so easy enough to weld. it has centre cab built from quiet heavy plate so probably a bit top heavy. could use half pipe like a staby i realize this would be a brave ( or stupid ) thing to do but if i cant stabilize it a bit more the cab mite have to get cut down any advice welcome. cheers.......

I wouldn't be welding anything to the outside of the hull but rather try putting more weight inside the hull along the keel. This will lower your centre of gravity and should make it a bit more stable at rest. A bunch of sand bags would work ok but some kind of tank that fills up with water when the boats at rest then drains out the back when you take off like the Barcrushers (i think) so that you dont have all the extra weight to cart around all the time.

The keel ballast idea does work well but I think it would be impractical to retro fit, depending on current under floor structure. Yes you may have to look at minimising any top heaviness as a part solution. Adding more weight as low as you can, maybe additional fuel or water tank below floor. There are things like rocker stoppers that can help by just hanging them over the sides. If you need more bouyancy on the chines then it could be possible to make sponsons like they used on the Stessl's and others, but that's a bit of a chore to design and fit plus the unknowns of how they could effect the boats performance and stability at speed and at sea.

thanks guys, it does have a floodable kill tank witch helps a bit and i like the cab for protection but it mite have to go.

I guess it depends on how much you want to spend. Do what a lot of others suggest on here about mods and talk to someone who builds plate boats and ask what they think. Origin boats always seem to be very helpful to guys on here so try them.

If you want a stable hull at rest then beam is the only thing that will do it. Flooded keels offer a bit more stability but nothing will come close to a wider beam. Reverse chines only deflect water and they DONT do anything for stabilty at rest. I think there is more old wives tales involving boats than just about anything else combined. Apart from cutting our boat inhalf and adding 500mmm to the guts of it then nothing else will work. Sell it and by a wider boat, easier and cheaper.

boats fairly beamy but a fair bit of deadrise allso. so i want to try and get the best of both worlds.Attachment 82175

Look into the Boat Collar,

Look into the Boat Collar,

second that. extra buoyancy and stability with little extra weight to achieve it - hoping to have one this year.

where can i find some info on boat collars, all my searches keep coming up as boat coolers.. are these the strapon type ones for tinies ???

um, no strap ons here - requires holes drilled in hull...

Im sure thats going to look great on a 5 or 6 meter boat. Never having seen this collar but I will say by looking at it that its essentially adding beam with foam. I didnt see it fitted to any boats over 5meters. Might work well on tinnies but on larger boats it will look crap and I would think interfer with the boats performance.

Can't look any worse than a Stabi Stu haha

thanks for posting the link ozynohts, they do look ugly but work great by the clips they show, i think i'm with stuart on this one, probably not as good on a 6mtr boat as the smaller ones. but along the lines of what i was thinking about welding a half pipe around the water line.. and yes it would be ugley...... i'm thinking the centre cab is going to be a duel consile.
