Default OH Educate me ,PLEASE

Hello Gentlemen,
I have recently acquired a vessel with a soft deck,I have cut deck most of the way out an Stringers are soaking wet also. I am no PRO in any way, nor do I claim to be.My question to the hull truth community is: what is the best way to level the Hull so i can get this Mess replaced?

NOTE: Boat is 89model 25' Center Console C Hawk brand. pics are as followed.

Cut out the stringers and glass in new ones.

Well, looks like you're off to a good start. If you're asking how to remove all the bad stuff, it's just a lot of elbow grease and patience. I'd also look closely at that transom. Looks like there are enough holes in it to make one worry.

Welcome to THT, and good luck with the boat. Keep the pictures coming!

(I got red x's, so I'm re-posting your pics for you)

Yours is not a mako, but you could still learn a lot looking over similar rebuilds over at classicmako.com. also, be sure you have the boat well braced and secure before you start taking out the support structures. If you are not careful the boat will flex out of form and be untrue when you start reinforcing later. Good luck.

Nice project - I ended up doing exactly the same thing to my first boat, which is how it earned its name 'grodywhite'.

I leveled the hull by using a high quality 6 foot level attached to a very straight board held on edge across the gunwales. I had bottle jacks underneath everything and jacked as necessary, then installed the cribbing as needed. I started at the transom and worked my way along the cockpit towards the bow. For measuring along the front of the boat I used matching chocks of wood to block the level up high enough to span the arch of the flush deck in front of the windshield.

I also took the time to sight along the gunwales, looking from the stern towards the bow to see if there was any hogging or sagging of the shear line. Once you cut the stringers out, the open hull is very flexible and you would want to ensure that the hull lines are good before you start reinstalling the stringers.

Good luck!

thank you all for the replies and beefy for re posting the pics. anyway we have moved the boat under good shelter and out of the freezing wet weather. we have acquired plenty of marine grade plywood, and hopefully santa will bring me some fiberglass epoxy, hardner, cloth, etc. i have a local gentleman who seems to know the ins and outs of this since he has worked for hatteras yachts for several years as a professional boat finish carpenter. he seems to know what hes doing. he said to let all weight rest on the keel on a soild piece of wood (4x6, railroad tie etc) but another boat builder has told me to put the weight on the chimes( that doesnt sound good to me) stringers will come out one at a time, starting with the middle(bottom center), out. does anyone have any personal experience tips about this?

Leveling a boat so that you can apparently repair/replace stringers/deck?....pretty difficult....generally making things "level" and assuming that that is where they belong in relation to the rest of the boat can lead to some serious "oops"...measuring and remeasuring and checking the object's orientation to the rest of the boat is the real way...you have locations now to everything that needs to be repaired, so go with it....take time to learn about new materials and resins/fillers/paint and make sure that you have checked the transom and the rest of the hull for rot....that is a good hull and worthy to be brought back...been there done that...ALOT of work and whatever budget you are considering...double the money and time and you will be close...have fun...

I see what you are saying,an it makes good scents to me.Dont you think 1 stringer at a time with boat blocked up well, starting at bottom center working my way up would be a good approach?That is my plan for starters

Install a couple of sturdy 2/4's attached side to side at the transom, and midships...when the hulls are made they are popped out of the mold without the stringers attached, but, if you remove the stringers without supporting the hull properly, it can bow and flex upward....add some more keel and chine support, gut the boat but leave an inch of existing glass in place to mark locations of the stringers and the deck, tank, etc...grind away until you get raw, fresh glass and go back with epoxy resin like West system or something like it...prepare to get itchy...nice project and worth it...how's the transom?....

Believe it or not,local guy tapped all over transom with his pocket knife,listening for differnt tones an he says overall it sounds solid.I personally think it will get replaced also.Cant hardly see doing all that an leaving existing wood in transom.At least take a long Look at existing before final decison is made.Im itching to get started .LOL

progress is slow, but still moving in a FORWARD direction. my son and I have gotten the boat off the trailer today. its got 8 jack stands total around the chimes and blocked up on the keel BUT its still not level, we have noticed the hull still has a twist in it due to the different heights of the jackstands. we're still working on that. we also noticed the painted waterline on it is no where near even, about 1 inch difference from port side to starboard side wish us luck, the local pro is supposed to come look at it tommorow[IMG][/IMG]

Looks like a great project. Good luck and send pic's. Is that a SeaOx, Privateer? Disregard, I didn't read the C-Hawk line.
