lamination deck to haul

[mkhammer]

My 98 convincor appears that the deck is bolted to the haul and not glassed together. It doesn't seem to be a problem. I am just woundering if all checkmates are constructed like this. I noticed some other brand quality boat makers glass thier decks to haul to make it one piece. I'm not sure what checkmate construction proccess is in this area. can anyone tell me. Its the only thing about my boat I'm concerned with now that I added more power.

not that I am a boat builder or anything,but EVERY boat I have owned or looked at had the deck and hull in two pieces.I dont think any manufacture glasses them together.Screws and rivits are the norm.

Yes...MOST are fastened together as Fnshrmaster stated... It's quicker, cheaper, and more convienent for manufactures to do so. The good thing is that if you ever need to do major work, the deck can be pulled for service.

and YES...Several manufactures in the custom or race lines are bonding them together to be more of a rigid one-piece hull structure...they are STRONGER this way as it distributes load to the entire structure (not just screw or rivot points). It's a great plan for hulls with high power or seeing heavy wave abuse that tends to work out screws and rivots....the down fall is hope you never need to seperate the deck from the hull!

I bonded a hull to deck in a 21 Eliminator Daytona I had with an 800SC motor...it very much helped stiffen things up!!!

Checkmate bolts AND rivets the deck and hull together...Better than most.

Bolting is more than enough......we never even glassed our race boats together! If you do glass it together....and have to take the deck off for any reason ...the boat is basically junk ....you'd have to cut it apart ! http://www.checkmate-boats.com/infopop/emoticons/icon_biggrin.gif

SOME MANUFACTURORS USE A PUDDY CALLED PLEXUS TO BOND THE HULL AND DECK TOGETHER. WHEN THE PUDDY CURES IT IS STRONGER/HARDER THAN THE GLASS ITSELF!! MOST HIGH PERFORMANCE OFFSHORE BUILDERS GLASS THE HULL AND DECK TOGETHER FROM THE INSIDE. THE TOP DECK IS FASTENED TO THE HULL USEING SCREWS TO KEEP IT FROM MOVING, THAN THEY GLASS THE SEAM FROM THE INSIDE WITH 6" OR 8" WIDE LAYERS OF GLASS AND VINYLESTER RESIN. FOUNTAIN POWERBOATS BONDS, RIVETS AND GLASSES THEIR HULLS TOGETHER. SOME OF THE CUSTOM BOAT MAKERS BOND THE HULL FIRST AND THAN USE THE RUB RAIL SCREWS TO ADDITIONALLY FASTEN THROUGH THE LIP/SEAM FOR ADDITIONAL STRENGTH.

I'm not having a problem. I went to elimanator factory and all thier boats are bonded together now. I have owned to Halletts in the past that were bonded also and starting to notice a few others. I now have a 800 hp engine just woundering if any body has bonded thier mate together or seen any stress cracks from high hp. I don't have any yet but it seems my dash area has some flex to it.

How true KIP!!! I "bonded" my Eliminator because of my power and hull combo... It really NEEDED it badly (light lay-up), and the solid joining made an unbelieveable difference! http://checkmate-boats.com/6/ws/,s,8626072361/Graemlins/devil.gif

I think a lot has to do with the hull construction and it's intended use... http://www.checkmate-boats.com/infopop/emoticons/icon_rolleyes.gif

Glad to hear your Checkmates don't need it! http://checkmate-boats.com/6/ws/,s,8626072361/Graemlins/biggthumpup.gif

I AGREE WITH KIP TO A DEGREE. SMALLER BOATS THAT ARE USED IN LAKES AND SMALL CHOP NEED NOT BE GLASSED TOGETHER PLUS IT CAN BE VERY DIFFICULT REACHING AREAS TO GLASS A SMALL BOAT TOGETHER; PLUS YOU CAN ALWAYS PULL THE HULL/DECK APART IF NEEDED. HOWEVER, IN LARGER BOATS THAT RUN OFFSHORE, (HERE IN SOUTH FLORIDA'S OCEAN AND GULFSTREAM YOU CAN TYPICALLY RUN IN 4-6'+++ SEAS THAT ARE SOMETIMES REALLY SNOTTY)THE STRUCTURAL INTEGRITY THAT COMES FROM A GLASSED HULL/DECK JOINT IS UNSURPASSED. IT IS ALSO MUCH EASIER ACCESSING THE HULL/DECK SEAM ON A LARGER BOAT TO GLASS THEM TOGETHER. WHEN I WORKED DIRECTLY FOR ACTIVE THUNDER BOATS I WOULD HAVE CLIENTS FLY IN FROM TEXAS, MO, OHIO, IL, VA, MD, ETC THAT WOULD TELL ME HOW ROUGH THEIR WATER WAS AND THAT THEY NEEDED AN INDESTRUCTABLE BOAT. ONE RIDE IN THE ATLANTIC OCEAN ON AN "AVERAGE" DAY HAD THEM WHITE KNUCKLED AND CHANGING THEIR PANTS!!! MOST HAD NOT EXPERIENCED WHAT WE CONTEND WITH IN THE OCEAN BUT THEY ALWAYS FLY HOME WITH A SMILE ON THEIR FACE AND DREAMS OF BEING AN OFFSHORE RACER!!! http://checkmate-boats.com/6/ws/,s,8626072361/Graemlins/thumb.gif

Maybe kip could answer this one.
On my 98 253 convincor the dash has some flex to it. When I installed my hydraulic helm I noticed that the dash was not really attached to the bottom panel that has the foot rest built into it. There was one or two screws in it at the cabin door jamb side. when I hit any chop it sounds like the dash is slapping on the bottom panel below it. I was thinking to join these together some how but it looks tough to do without hacking into my boat. Any suggestion input from anyone would help. Its the only area I feel I have a problem with.

post a picture of your problem then we can all brainstorm it http://www.checkmate-boats.com/infopop/emoticons/icon_cool.gif

[mkhammer]

Yes I will post a pic soon
Thanks

Structurally speaking, glassing that seam together isn’t any stronger than using bolts and rivets, unless you’re talking about glassing IN ADDITION to the bolts and rivets.

In my opinion, if the mfr’s you’re talking about are glassing the seam only, that’s not good.
