    Hi,
    I have a 16ft ply fishing boat that I recently acuired that I am giving a freshen up.
    My first question is how long should I dry the boat out for? It was sitting in a blokes front yard for the better part of 12 months full of water.

    My second question, Is Bleach soaking going to be enough to kill the rot spores that are evedient throughout the boat?

    Hi... I can't answer either of your questions but, do you have any pictures of your boat....
    I'm restoring / rebuilding a 17' plywood boat myself so, I'm interested in what your boat looks like.

    Hi Vic,
    Yep I sure do, not alot at the moment but more to come as work progresses.
    These 2 were taken about 2 weeks ago with her sitting where I found her. A trip to the local chandlery for some bits for dad's boat revealed her sitting in the carpark of a business 2 doors down, A quick investigation into the ownership and $300AU about $220USD she was hooked up to the ute and heading home with me. My first boat :) . She is 4.8m X 2.35m and constructed of Oregon and ply with a little oak in the gunwales and chines

    I have some big plans for her including an updated more modern foredeck/cabin and a 1m extention to the stern with a pod and dive platform wich will bring her from 4.8m to around the 6m mark. with a beam of 2.35m I dont think it will look to bad.

    I checked out your blog some great picks and story there.
    I will be following along and hopefully picking up some more tips and tricks

    Cheers Alister

    Hey Hey Wood Boat:

    Thanks for the flowers. A little heads up... Check out your trailer...

    A trailer for a wooden boat is set up a bit different than that of a glass boat. A wooden boat needs to be supported directly under its stringers (for and aft) as well as the keel. My boat came with a trailer that was set up for a glass boat (it had rollers under the hull) and has consiquently suffered some damage to the hull (the weight of the boat pressing down on the rollers actually pushed in the hull) near the transom. It is repairable though.

    Also check out all of the wood carefully... Paint and old repairs can easily hide existing problems... like my keel was.

    I'm not going to say that you can not extend your stern another meter but, you would be wise to research this idea in great detail before you cut your transom off and start something that just might not be able to be repaired. I have also thought about doing this to my boat.... but, I think that it would be a lot of work for little reward. Rather... I plan to use the restoring / rebuilding of this boat as a learning platform and actually build a larger, longer boat later down the road.

    To make your boat longer:
    You would have to extend the keel... this is not too hard.
    You would also have to extend the hull sides... what kind of joint would you use for attaching more plywood to existing plywood? If you look around the net at some of the sites where people are building boats with plywood hulls the plywood pieces are attached together, end for end, on the bench using a scarf joint to make one long piece then cut to shape and installed on the boat to make the hull. (there are several sites listed on my blog).
    Also, you would have to extend the Chines on both sides.

    As I said, the keel can be extended without much trouble (as I have learned) but, how to extend the rest of it and maintain the boats structural integrity is a bit more complicated. But don't let me discourage you... There is a wealth of information on this forum and aside from the joking around there are several very knowledgable people who are more than glad to help a fella out... some of the joking around is really quite entertaining too :D

    My dad taught me that "If you can imagine something, you can do it".

    Looking forward to updates and more pic's of your boat.

    By the way... my boat started out as a "freshen up" project too... for what it's worth :D :D :D

    better off with antifreeze...soak the wood with it and it will kill the spores and preserve what's left of the wood. CPES applied after a few weeks of drying will help stabilize the remainder of the wood then you can work from there.

    Hey Steve:
    How goes it out in Iowa ?
    I stumbled across your web page not long ago and have been wanting to PM you but just have not got a round to it.....

    Way too much work and certainly not enough play...witness the site is woefully behind the times. I have a boat abuilding that isn't near where it should be, especially seeing as I want to sail it this summer on my vacation. I barely have the hull stitched together and turned over. I am using down time at my primary job (I have two) to pre write snippets of building instructions (for other plans) just so I can cut and past large chunks of common stuff then modify to fit the design. I did finally order the sail for the boat...just a couple of days ago, plus the pintles and gudgeons for the rudder. I still have to cram 4 months of building into the next 2 but I'm kinda stuck on the keel. I need to have it so I can adjust it to get the best balance before commiting it to plans, but it is a fixed long keel so juggling the two opposing ideas is causing headaches. I think I finally have it worked out though. Time will tell. Keep an eye on Duckworksmagazine...I have a plan that is going to be an exclusive (but free) download from there...Duckskiff14...it is due in the next few weeks.

    So...how 'bout you?

    That is a very true statement about vision and imagination there Vic.
    I have spoken to several marine engineers in the last 2 days and all have given me the go ahead with regard to my plans with all offering some good advice and one even offering to draw some artists sketches of what she will look like based on the supplied photos, All of this is very encoraging and heartening so I will continue my 12hr days on her till fully stripped and post some pics tomorrow displaying where I'm at

    Alister

    P.S. How much effort/experience is required to create a BLOG similar to yours detailing the project?

    The Blog

    Hey Wood Boat:
    Good deal with the go ahead on the extension plans :) .

    I'd love to know (in as much detail as possible) how you plan to do this. I'm at the point right now (on the boat... not financially) that if I wanted to I could.

    As for the Blog / Website of mine...
    If you can post a picture here on this forum... You can build a blog. There are many FREE blog sites. BLOGSPOT is what I choose to work with and they have many FREE templates... mine was free.

    My blog is built using one of their standard templates. I however, not ever wanting to do anything standard, spent many hours anylizing the HTML code used to construct the template and "TWEAKED" it a bit here and there. I don't know anything about CODE or HTML but, it's not hard to figure out how to make a page WIDER or a certian element LONGER. It does take some time and determination (and a few notes) to figure it all out though. I figured out just enough to get what I wanted. As a matter of fact, if you look (while your typing a reply here on this forum) look in the top, right corner of this small window you'll see a couple of "A's" ... a small A and a large A that is underlined... this icon is used to "switch" what your typing into HTML mode.

    An example of HTML (if your not familiar with it):

    If you insert a "B" in blocks like this at each end of a word or phrase your word or phrase will become "BOLD".

    Better yet... as a simple example you'll really be able to relate to...

    Try this:
    Type out a reply to this message (as you normally would) and be sure to use some functions like BOLD and ITALICS and UNDERLINE. Assign some COLORS to some words and maybe even change their FONT SIZE. Then click the icon button in the upper right corner to switch everything over into HTML CODE and look at what you've typed... What you'll see is really not that hard to figure out.
    It gets a little more complicated when your trying to change a page's (template) layout but, I'm just a truckdriver... and I did it.

    Hello and Welcome Alister,
    there is a great Australian product for killing wood rot called 'Blue 7'
    http://www.woodart.com.au/a_intergrain11.htm
    last year as far as I can tell it got discontinued (because it is toxic enough to actually work),
    However, if you call around or have a friend in the Hardware trade, you should be able to rustle some up.
    My carpenter (and boat-nut) uncle put me onto it, and swears by it.

    How bad are the rot spores?
    are there any soft spots?

    as you have probably learned, fresh water is a wooden boats worst enemy, so you would want to have a real good poke and knock around.

    Good luck.
    Hans.

    EDIT- to add, if you do go the penetrating epoxy route, as CPES can be a little hard/expensive to get here, I think it is Epiglass that do a wood preserving (penetrating) epoxy, that will inhibit rot. Evidure apparantly does not have the rot killer stuff (glycol's- which is what is in Antifreeze) in it anymore, due to problems it causes with the epoxy.

    Thanx Hans I was looking at the Northane range as it is a little cheaper
    Im not even sure that I have got rot at all after some looking and probing the entire floor was stained with a green type stain that has since been ground off revealing good solid wood with no actual rot being found anywhere on the entire boat so from what I can assertain I may be just being parranoid

    Hi Vic,
    Below is 4 photos hopefully detailing the construction of the extention and also where Im upto thus far.
    The first photo is a pic of an aluminium boat that has the stern very similar to how Im wanting mine to turn out.
    The following 2 are some roughouts that I did in pain as a guide to set in my mind the basics of construction and are also the drawings that were okayed by the marine engineer.
    The fourth is just a progress pic

    Cheers Alister

    Use scarf joints to tie the stringers and other fore and aft structural members together. The joint you have drawn will create stress risers at the corners on the inside of each joint, which is weak. 8:1 or better ratio for the scarfs.

    CPES and other penetrating epoxy products, only work if the whole piece is completely surrounded and entombed in the cured plastic. If it is just painted on the available surfaces it will trap moisture, that has gotten in from the uncoated sides and you'll speed up the process. If you can't disassemble and encapsulate each piece, then use paint and keep it in good shape.

    Hey Alister:
    Looks like your on the right track...

    My stringers ar different... only two > made of 1" x 6" solid wood (? what kind) standing up on their edge as seen in the attached pic.

    Small Keel (1 7/8" square), two stringers and chines... that's it on mine.

    Seeing your idea and pic's makes me think that extending mine might not be all that hard. Got any ideas how I can drop my old chevy inline 6 (292) into her !!! I've got a 4 speed truck transmission too.

    See ya later............:D
