I've been wanting to add a ladder to my 18' fishing boat and it's kind of morphed into me wanting to add a swim platform since we use it just as much for family outings as I do for fishing. Ladder so the kiddies can get out of the water and also in the event I accidentally go swimming while fishing. A plain ladder doesn't work with this boat and I'm not really thrilled about the swim step ladder combos, so I've been tossing around the idea of adding on a swim platform like a ski boat. The problem is, this is a fishing boat with a kicker bracket so I can't just run it full length and make it look symetrical. I don't want it to look like I hacked back a porch on the boat, so I thought I'd see what you guys think, good bad or indifferent...

I'll have to make up a couple custom aluminum brackets to fit the boat right, and I'm kind of torn on what to make the deck out of; King Starboard (heavy - expensive) fiberglass (lot of work - expensive) teak, cypress or redwood (easy and cheap). The whole thing should weight about 50# if I use wood, a bit more for fiberglass, probably 100# if using Starboard

Here's a pic of what I have in mind, the deck will be about 60"x24". Let me know what you think (even if you think it looks like a porch :lol:)

I don't think that would look that bad not going all the way across. Do you have any large marinas around that might have old parts like brackets and swim platforms? Or go the full width and then bracket your kicker to the swim platform. I believe they make a swim platform kicker mount. You weights seem high too, especially 100lbs.

No marine scrap yards out here that I could pick up a used teak deck. I found brackets for $25-30, but going to make custom brackets so I can use some of the existing bolts in the transom, less swiss cheese made out of the transom.

I don't think the fishing gods will like this one bit!:facepalm:

You're probably right, I'll call it a fishing platform to keep Nereus appeased :D

Since your in Las Vegas, fishing & boating season won't really end for the winter, but watch CL & evil-bay for a platform for/from a narrower beam boat that you could make to fit a 60" wide & off center installation. And look for derelict boats in storage facilities & the desert, as the tough economy continues, luxury items like boats will continue to be left behind.....

you can check with greatlakesskipper.com for platform parts ans see if they have what you are looking for. I had a motor bracket molded on to my old bayliner swim platform. see if you can find one like that.

How about a removable swim platform? On for family outings, Off for fishing days.

If the platform has it's own structure that could mate with some nice looking brackets that stay permanently attached to the transom you could install or remove it in 15 minuets the evening before you plan on going out. If you fab up amount for your kicker that attaches to the same mounting points you could swap that on and off just a easily.

For boarding in case of going overboard while fishing, the cavitation plate makes a nice step. Or leave a loop of rope attached to one of the cleats so you can pull it overboard and get a foot in to for a boost up.

Re: Swim platform..... on a fishin' boooat

Hey I would go for it that is what I am going to to mine got grandbabys (7yr,s to 18months) we usally beach boat and tie the tow tube to the boat and let them play on it. Doing carpet now almost done and upholstery now platform will make it that much more fun and like you said safer. Plus I hate towing the tube from place to place will be able to hook up on the platform should make it easier. The big kids love the tube runs and the wife also so it has to go when the clan is all there.

I'm just hoping a big striper doesn't get fouled up in all the stuff hanging off the transom, that I can't see anymore...

LOL, I tell everyone my daughter spells the word "fishing"... s-w-i-m-m-i-n-g :lol:



OK, for the nitty gritty. (no pics on the build, I'm the worst at taking pics while I'm all grubby and working away...)

I made the fishing platform brackets out of a couple sections of sandwiched 1/4" thick aluminum angle that attach to the boat, a piece of 5/16" aluminum plate angling out, then 1/8" aluminum angles to hold the platform to the plate aluminum. If that makes sense... The plate slips in between 2 sandwiched angles (then bolted) so it's removable. 1/2" bolts to the transom, 3/8" bolts attaching the transom angles to the plate, 5/16" bolts attaching the platform angles to the plate, 1/4 bolts into the platform Working with the thick aluminum wasn't bad, but I did need to buy a $50 aluminum blade to cut it on the table saw and miter saw. I ran into a couple issues working with the aluminum:

1- A cheap Ebay $30 aluminum cutting blade will loose 1/2 it's teeth cuttin plate aluminum (buy $50 blade).
2- A 10 year vertical belt sander belt will shred trying to eat through 1/4" aluminum (order replacement belts)
3- Aluminum angle isn't always a perfect 90* angle (supplier replaced a piece that was really tweaked).

I was thinking of using $30 off the shelf swim platform brackets, which would have certainly been one heck of a lot easier, but I don't think they would have been strong enough as I only wanted to use 2 brackets. I fish in gnarly conditions and know this thing is going to get pounded, so I wanted to make it strong.

SP Bracket.jpg

The platform is made from 1 sheet of 1/2" 5'ply exterior plywood, cut down and the 3 pieces of plywood laminated together to get a thickness of around 1.5" thick. Before laminating on the top piece of ply, I drilled all the attachment holes, let slow curing epoxy seal all the holes, then epoxied 1/4" T-nuts into each hole,,, then the top piece of plywood was laminated on. Sawed off the angled sides, a little bit of routering and I was ready to epoxy the thing.

Epoxying wasn't too bad, but the slow curing epoxy from US composites takes a long time to cure, even in 100* temps. I saturated top and bottom with epoxy, next day a layer of 1.5 oz cloth on top, next day a layer of cloth on bottom. Then I got the bright idea of wrapping the edge with 2" cloth tape, which would have worked well, but the cloth tape didn't like to lay down around the radius's, and I was fighting it. I hit the whole thing with another coat of epoxy, then sanded it. I found that the top and bottom were perfect, but the edges had all sorts of pin holes from the cloth tape that didn't lay down properly. Ended up scrubbing the pin holes clear, coated the edges with 30 minute epoxy, then a heat gun to pop all the bubbles,,, 4 coats to give me enough material to work with. (Needless to say I should have just laid another layer of cloth on top and bottom instead of trying to tape the edges, it would have been quicker). Sanded everything with 80 grit, 150 grit, 220 grit, then primed it. It was a 2-part automotive primer and that stuff is really tough, lots of sanding,,, 100, 150, 220, 320, 500.....

I had tan and blue Nason 2K automotive paint left over from repainting the transom, but not much tan, so I decided to 2-tone the platform. It was weird painting the blue as I was painting it upside-down, and on a bench that made access to 1 end difficult,,, hence 1 run/sag on the top edge. (Can't see in pic, need to buff it out...) Zool gave me a a tip on dry-spraying anti-slip through a paint gun which worked out very well. I taped off the tan section, sprayed: blue - anti-slip - blue - anti-slip -tan- anti-slip - tan - tan. I'm really glad I decided to shoot the 2 coats of blue first as I ran out of tan right at the end, used all the left-over automotive paint that I had.

All that was left was bolting everything together, standard,,, goober it up with 5200 and let my son have the pleasure of cleaning up all the excess 5200... :D I didn't want the ladder rattling around ("fishing boat") so I bought some big clear tubing, blew it up with my air compressor for a day, then slipped over the tubes of the ladder to keep it from rattling around.

I have a Troll-a-Matic trolling plate on the boat that can be a pain at times when I'm not trolling, blocks the prop when trying to reverse. Soooo, I made a bracket (not on yet) to attach a line to the trolling plate, to keep it up at a 45* angle. Probably make the line out of some old spectra fishing line, 25-50 wraps, what ever looks sufficient to keep the line from breaking while in reverse...

Re: Swim platform..... on a fishin' boooat

I think JnG was right... We fished for 2 hours and didn't catch anything, couple bites but nothing that wanted to play. (Maybe I upset the fishing gods... :facepalm:) It was midnight, so we decided to crash out, instead of staying up all night long waiting for the fish to turn on.

BUT, the fishing platform worked very well and the kids loved it while tubing and swimming. The only issue is that I don't have enough anti-skid on it. It works fine for awhile, but then it gets sun tan lotion on it from people climbing on it and it gets slick. Wash it off with a towel and it's good again. Too much open area that can get slick. Soooo, I need to buy some more paint and hit the tan area again, load it up with anti-skid so the whole thing has grit on it, no open areas.

The kids said I did a gracious dismount stepping off the transom onto the swim platform, and then slipping directly into the water.
