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

If your beam is close to 2.5meters, welding extra chambers will increase the width and make it to wide to tow normally. If you want stability get a boat with a small deadrise 10 degrees or a Bloody Cat.

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.

Why pipe?.......get something pressed up,it would be cheaper and you could come up with a profile that may actually look good.......people may even copy your design if it looks good....

Messing with your centre cab would greatly reduce the value of the boat and do SFA to make it more stable IMO. There is no way I would make such a drastic change with no idea if it would make any percievable difference. MAdness.

As mentioned already,the stability issue is caused by the deadrise of the hull.
Modifying the centrecab will do nothing but cost you a lot of money and devalue the boat immensely.
It is a compromise you make when you purchase a boat.
Go with a deadrise that gives you a softer ride and unstable at rest or go with a deadrise which gives you that pounding while underway but extremely stable at rest and while fishing.
It is one factor in a hull that most people either neglect to think about or are unaware of at the time of purchase.
Personally I prefer a boat that is more stable at rest than a hull that gives a smoother ride while travelling because at the end of the day I cannot stand a boat that lays over every time someone moves around the boat.
At the end of the day you don't have many options to fix it cheaply because of the hull shape.

This is the answer.

pm feral cat for details.

firstly - some photos would help. Secondly, some details and specs, such as deadrise; beam; Do you have a self draining deck or what. (self draining decks are higher - therfore so is centre of gravity = more rock at rest) - (Everything is a compromise)

What Breed of boat is it?

Do you have anything else above deck? - ie; when I bought my Dehavilland Trojan - it had 2 off 170 litre fuel tanks which were the helm seats - above deck. Needless to say - they went - replaced by an underfloor tank. Also not to exited with the idea of sitting directly on the fuel tank

This is all info we need to know - otherwise our advice is pointless and useless - no offence to any of the previous posters of course

thanks mark, your rite i am holding out a bit, but I'll come clean for advice and i got nothing to hide. the boats 6 mtr lightning, no dought a lot of you have seen it for sale for some time. i'd love a fisher or origin but i could die before i can afford one. the boats about 12 years old and hard to find much info on. the thing i like about them is the 6mm hull, you could almost park on the bommies and get away with it. so i'm trying to cheat and buy a boat with a fair bit of deadrise and bitch about stability at rest. to ad some prest up ally along the chime line to act as air pockets for stability is easy for me to do but purAttachment 82203ely experimental. any way you'll see by the picks it's defiantly top heavy. so the smart thing would be to remove the top and maybe replace it with Attachment 82202some thing lighter. you'l notice the gunnel's are wider the chimes which don't help. hope the pic's work.. cheers ( and excuse the spelling please)Attachment 82201

[bobbyb]

if i could add some flotation around the boat and make it handel like that tinny with the boat collar video( without looking to fugly ) i'd be a happy man.......

[SunnyCoastMark]

Hey Bobby,
Can't get the attachments to work? Comes up as invalid. Will google your boat though - don't know a lot about them, but like the 6mm hull

[Stuart]

Its wishfull thinking that by welding a bit extra on the chines is going to help by traping air. I hate to be blunt buts not going to do a dam thing for stability on your boat. In reaity you should sell the boat and buy something that will suite your needs. Cutting ands shunting is going to do 2 things, one, your boat will be worth zip. Two, you go to all that expense and heart ach for zero gain and your boat will again be worth zip. Save the coin, sell the boat and buy something else. Reducing a boats weight by that much usally end in the boat riding like a peice of sh!t. I have been in a few boats that had heaps of weight taken out. These boats whee crap afterwards and the owners wished they never did it.

[ozynorts]

Hey bobby, is this the boat?

[bobbyb]

no mate, google lightning centre cab and i think you'll find an old add for it. stuart, i know what your saying , it is a bit out there for most people. but the beauty of ally is you can cut and shut all you like. i'm thinking a sealed chamber that holds enough air to make a difference. but how much ?. so just thinking out of the box. any way as stated the centre cab will be come a duel concile most likely..

[Dan5]

Heres a picture of what a mate did to his 6mtr Phil Curran (CDM) kit boat to give it more stability........Looks ugly but his final plan is to fill in the top section aswell and use it as some sort of storage.......

I have acctually stood outside the boat underway for a laugh.it has made the boat alot more stable at rest..........A WA naval arcitect was consolted before the "spontoons" were added.

Any way it has been done so could be done again.

I wish i had a side on shot for you but don't have one sorry.

[ozynorts]

is it legal for towing width?

[Horse]

Bobby, try adding some weight into your kill tank or hull for a trial. Adding chines will do little for the stability. Its essentially a function of Centre of gravity, centre of boyancy, beam and mass. A flooded keel would make an improvement but would be hard to retrofit
