Re: OMG , i need help , BIG TIME !!! 1985 invader deck,hull ???

I used 1 of these to trim down to very close to the hull:
Multitool.jpg

Got mine on sale @Harbor Freight (HF) for less then $15, it's not a Milwaukee, it's an XYZ branded HF multi-tool. And get a few different blades for cutting different areas, HF has several to choose from. HF also sells an attachment for an angle grinder that works similar to the depth adjustment on your circular saw. WoodOnGlass posted it somewhere, but I don't have a pix sample.

Many 'free' hand it w/ the angle grinder & metal cutting disks, but as you've already found, it is fairly easy to run a power cutting tool through the hull by accident. Almost all of us have, or do, no worries.... If you can trim it down fairly close, it is easier to use the grinder to take it down the last 3/8" or so, leaving just an 1/8" or less, then use a 24grit flap wheel on the angle grinder to take it the rest of the way off. You'll use something similar to the flap wheel to rough & scuff the hull for deck tabbing to the hull as well...

When you're working on putting it back together and are doing the transom & stringers, you'll have all the materials on hand & can repair the hull at that time.

That covers Q's 1 & 2, for 3's answer, you'll need someone w/ a similar boat or more knowledge then me to answer about getting the deck out from under bow structure. I suspect it will involve removing the cap....

EDIT: I didn't have to replace my stringers, so I took the deck line off entirely all the way around the inside of my hull, others often do as rick suggests leaving a lip for reference. Either way can be correct, just be sure the lip still has structural integrity if you're leaving it, you will be attaching to and over it.......

And ive got another question about the space in midle , there was no foam ??! So i dont really understant why there is an empty space ??!

If I'm reading your pix correct, you're asking about the area in the middle of pix#4. It's been a bit, but It doesn't look like you've found a boat that was previously repaired, or at least my quick scan of your posts doesn't reflect it was.

A ski locker is my 1st thought, or if this Invader model was also available as an I/O, it might have been for an under deck fuel tank, which you might consider.

Should be able to w/ no problem. If it has never had a repair, and the original manufacturer left the center open w/ no foam then it should be plenty of room for a great big ole ski locker.

Depending on your tastes & plans for finishing the interior, there are many options for the ski locker 'lid'. Start surfing the net, evil-bay & CL for ski locker lids & frame. 1 w/out the other will make it more difficult to install, but not impossible.

A plastic or similar material, & teak are available commercially, and then you can also do a solid 1 to match the deck. So there are some different options, and each have benefits & much different looks. Friscoboater is the last fully documented ski locker lid install I saw @Iboats. Sorry don't remember which 1 of his threads had it. It may also be on his YouTube channel.

Not necessarily ALL the glass but you need to sand down any glass that you will be applying fresh glass to, in order for the new glass to have a good bond with the old. Also you ALWAYS wash the old glass down with Aceton right before laying the new glass on top of it.

I've got a similar Invader (1987 16ft.) I still have the original teak that went over the ski locker. I can get you the dimensions next tuesday or wednesday (headed to FL tomorrow afternoon). Here's my thread, http://forums.iboats.com/showthread.php?t=545549 , I don't seem to be any farther along than you right now, but you never know if you'll find something useful :)

regular 1" - 1 1/4" pvc is fine....just dill your holes,run your pipe and PB it in place around the holes...you can even tab it to the hull with a few scraps of glass to keep it from rattling around.

I haven't taken it off yet, I plan on looking into that when I get back from FL.

How long is your boat?

Haha, I know what you mean! I *think* the length is listed on the cost guard capacity sticker which is located near the dash on my boat. On the left wall of the walk through area to the bow seats.

How thick are the stringers? I recommed Arauco Plywood from Lowe's
Check the link below in my signature on how to build em

No need for PT lumber, it's heavy & damp from PT process. A good void-free core, exterior grade plywood in a 1/2", 5/8", or 3/4" depending on your best estimate of what is coming out of the boat (3/4" for the stringers & bulkheads, and 1/2" for the deck (floor)). Aurauco (sp?) and MDF are both good choices, but have limited availability in some markets. There are other plywood choices available as well, they just need to meet those guidelines: Void-free core (find the cheapest grade of 1/2" or 3/4" ply at the lumber yard, look at the laminations of wood along an edge, there will be places the wood is missing, these are voids in the layers, and weaken the overall integrity of the plywood), constructed w/ exterior (waterproof) grade glue, and will generally be more expensive then other similar thickness plywood.

NOTE: MDO has an exterior skin (either 1 or 2 sides) that 'looks' like it's been covered by a regular grocery PAPER bag, is made just like regular plywood, multiple layers of veneer, and is made with exterior waterproof glue. IT IS NOT MDF, which looks like ground up wood chips glued into a sheet. Most furniture you can buy in a box & DIY assemble it at home (Wally world & Target stuff esp) is made of MDF w/ various exterior finishes.

Please read thru the tips & helpful info from Don S at the top of the restoration forum homepage (it's called a sticky) and read thru oops' hull extension thread, it has a handy index @page1....I think I mentioned this & other places to read, study & learn, in an earlier post....

You want to take extremely accurate measurements of everything before you start taking it apart. Take tons of pix, I often take a pix of my tape measure showing length, width or whatever, so that info & measurements for reference are all in the pix. If you can save any of the existing wooden structure for use as a pattern, do so & label the pieces as best you can.

Before you start putting the plywood deck back down, you'll want to cover both sides & all the edges of the cut to fit pieces of plywood, w/ poly resin & CSM.

You'll want to have a lot of reading done before you start the put back. Once you've read & think you've learned way more then you ever thought you wanted to or would ever need to, read about that much again......

Each step will make more sense as you move forward, if you know what comes next & etc. That's 1 of the reason's i liked Friscoboaters video posts. It tied all the stuff I'd been reading about, and made it all make more sense. The hull, transom, cap, deck, stringers & the fiberglass & poly tying it all together work as a system. To some degree, each is relying on the others to perform as the naval architect intended.

Good luck w/ your project, hope your stay in dry dock is quicker then you expect, and you're putting her back in the water soon..

EDIT: I think wood has it spelled correctly....... And his signature line info is GREAT! Really good drawings for stringers, deck & transom resin & glass layups....

Home Depot carries the Arauco Plywood. You can also use Floor Underlayment Plywood. Good Stuff!!
