making new swim platform

[Jdm89supra]

OK well here it gose still new to the sight

I just recently finished my boat I thought. I have a 89 conbrio and it has the fiberglass deck and I had it wrapped with the rest of the Boat and now I am thinking on taking it off and makeing a teak deck to replace it.if I do this what are the down sides to making it longer for more Room when putting on a board concidering it is only like 20 in deep and three inches is tucked back under the back portion of the boat

? How much more stress is it going to cause being three inches longer or so
? Also added weight stress


Need thoughts I can make for cost compared to buying one

[michael hunter]

I made one a year ago for a buddy's Sky Supreme . I added about 3'' for the same reason . We went with African Mahogany because of the high cost of Teak. It has worked well so far.

I definitely wouldn't worry about the platform itself being heavier, but the extra 3 inches might be a bit of a concern. When you say you recently finished your boat I'm not sure what you mean. Judging by my own recent purchase (85 Rider) and what others have posted here, swim platform mounting for that era of Supra was a bit dodgy. I'll be pulling out my gas tank and putting in some big backing plates as soon as I get a chance, because my platform moves pretty easy, and the boat was bought for skiing.

If you are confident in your anchor points, I wouldn't think another 3 inches would be all that big a deal. If you think about using a 20" lever to pry something, how much more leverage do you get with another 3 inches. It's more, but it's not huge.

Nice job on the platform, very pretty.

[Jdm89supra]

Yea I will have to agree good Job

What I am dealling with is a late year December Moble conbrio which luculy I have the 90s model platform brackets which are the lock in and sliding pin my 82. Comp which I am.not.working on has fixed brackets its just to short I fiberglased in blocks on the inside transom when I did my capoff restoration
for this reason

I got some African wallnut today I love owning a wood working company 4.25 a foot

Michael - that platform is gorgeous. I've never seen a non-production platform look that good. Very impressive.

[michael hunter]

Thanks Rob that was the first one I attempted . I just built one for the pontoon its more of a deck than a swim platform . I made it out of cedar to save on material costs.

Again, excellent. I love that you build stuff as it should be built to last. Extremely solid, but not overdone either. You gonna put some graphics/paint on that pontoon (I like that size and drive configuration)?

As someone who has some experience building boating related projects, please chime in on the process I'm about to undertake. I've sanded by swim platform back to pretty much just wood. I've cleaned and scrubbed it with soapy water. I'm about to go back with teak oil using Sybermike's process of mixing with turpentine. Four applications with plenty of drying time in-between. The Turp/Oil mixture goes 75/25, 50/50, 25,75 and 100% oil. Any thoughts on this? It's not that I'm questioning Mike's process (he is another great craftsman), but I'm just wanting to collect all opinions before applying the oil. I spent about 3 hours sanding last night and then cleaned it thoroughly. I'm letting it dry overnight and today and am planning to start the turp/oil mixture tonight.

[michael hunter]

I have never refinished old teak but it looks to me that you are on the right track .

[Salty87]

give it plenty of time to dry after cleaning and after applying each coat of oil. you definitely don't want to rush it.

OK built this last Saturday 118791188011881

[TitanTn]

Very nice! How about some wider shots of the boat?

And oh yeah, Greensboro isn't that far away from Chattanooga, so be sure to sign up for the Southern Supra Reunion this summer!

[Jdm89supra]

I e thought about it its about three hours I don't know

[TitanTn]

I e thought about it its about three hours I don't know

It's actually a little more, but still not too bad. Between 5 - 6 hours.

[Jdm89supra]

how far is it from Cherokee nc because I have a house their didn't know if it was to far to drive for a day and back

[TitanTn]

Oh that's much closer. 2.5 hours max.

[Jdm89supra]

im thinking about it what all gose on their

[Jetlink]

Good times hanging out, talking boats, floating, riding and the occasional tech/repair seminar. :cool:

[chris young]

So did you add the 3"?

Nice job . Is that the African walnut? What finish did you use on it?

[Jdm89supra]

I wound up using African walnut and I added four inches with the arch for more room and racked the sides to stay out of the wake and it definitely stays out of the wake I think the old stock one was messing the wake up be house it is a nice smooth wash behind the boat now instead of spray and lighter than the fiberglass one
I used Cabot's three coats and baked it at 185 for three hours and it is solid

Just curious but has anyone seen a platform made from cypress?

[Jdm89supra]

i work with all types of exotic woods every day and hard wood like walnut teak roka will all last for years in and out of the water cypress will work but you really need a good oily wood like teak or roka . roaka is also called African mahogany or African walnut depending on the area it came from. but to answere your question yes I have seen a platform made of cypress also a tower a guy at smith mountain lake in va custom made both for his nautic it took him two years and cypress is not cheep

[2500HD]

so i'm tempted to build one out of left over rustic cherry from my house, i'm well aware that it is not water resistant and it will not, last but i have it. I think i will finish it with products from osmo that i used making a counter top out of a reclaimed maple bowling alley lane. mainly i just want to see a cherry deck off the back of my boat and next year i will probably switch to the mahogany.

[Jdm89supra]

use cabots oil stain it comes in clear and it will keep the cherry oily so it dosnt soak up water you can get it at any lowes for 10.00 hd pot dose not sell it only lowes use three good coats and it will be sealed for about three months it is a wipe on stain so middle of the year just hit it one more time it will last you a couple of years at least but a court will do a platform probably five or six times but I was going to go with cherry but decided not to I would do it it will look good. cabots is ment to be in the water and block moisture

[2500HD]

I'm familiar with cabots, we use it on ipe decks. I'm a carpenter by the way. While i like cabots i really want to try the osmo oil so far it has been good and what better way to test it than putting it in water every weekend. I'll let you know which way i decide to go. The only draw back is osmo is expensive but i think i have some left over. The cherry deck can also double as a template for my final design, big enough to start surfing from the deck but not interfere with the wake.

[Jdm89supra]

that's cool ive use to use osmo oil on oak wake skates when we use to make them sold a lot of them

[2500HD]

ok i made the cherry deck. by far not my best work but considering it started as rough sawn and i had no plan when i started its not to bad. I'll probably make a new one next year after i see how this one affects the wake.

looks good

[2500HD]

looks good
Thanks, the one glaring mistake is the 12 inch by 1/2 inch groove. I discovered that the offset on my little router is different on one side by a 1/4 inch. pretty stupid if ya ask me.

[Jdm89supra]

well look at it like this water will definitely have a way off the deck
