Ive been working on removing the wet nasty foam from under the bow of my project (19' Brendella tunnel). It was completely full of foam, but its gone now. Problem is I found a false floor up under the bow (only over the center sponson) . I drilled some holes and there was water under there too, so it needs to come out. Question is, do you guys think it needs to go back in (is it adding any real strength to the boat) ?? Or is it there just to have somewhere for the deck support to go.
I was thinking to do 2 supports for the deck and 2 bulkhead pieces like my Daytona has (it feels way stronger). Like this.
I'm not to sure you want to make this type of boat to solid I've been told they where very flexible hulls. mine is the same but it looks like you had to remove the one bulkhead they had to defoam your hull? I know my 21' Daytona is a rock compaired to my Centurion (same as Brendella) someone opened up your Daytona bulkhead alot also.

Yea, had to remove the bulkhead to get the foam out, it was cracked anyway. And yea, someone cut a bit out of the Daytona too (not me).
This is what the Brendella looked like before I started. Completely full of foam (wet nasty foam). It just seams like the foam was helping the boat hold its shape, its very flexible now. I figured doing something like the Daytona would help give it some support it lost with the foam removal.
either way you got to do some repairs. drill a hole in the false floor and see it wood is anygood first. if you drill and its black then you know you got to replace it. is take a drill and go as low as you can and drill the verticle part in the floor to let water drain out. if you have a dremel tool use it afterwards to make hole go to glass floor but be careful. raise the bow and get that crap out. if the false floor top is good then just remove the verticle section and you can ger a visual of whats inside and also dry it out. if not atleast you can see what needs to be cut out. ill tell you that is a job because of its location. if you never have tackled this id take it to someone . but if your confident then start removing little bits at a time.
Yea, drilled holes and drained it already (wood is shot), it needs to come out. Water drained out of there like a garden hose for a minute or so.
I just dont understand why it has that floor up there. If it needs it I'll redo it the way it is. But if it doesnt, I would like to do it the way the Daytona is. What do you guys think, is the false floor doing something that the 2 bulkhead and 2 deck supports idea wont do ? I dont want to make something thats not safe.
I think I would take a good sized hole saw or sawzall and cut a inspection hole on the vertical side big enough to see in good with a light or dig around in the floor ceiling areas to verify the wood condition. I believe the problem is the false floor your seeing is the tunnel support that runs the whole floor under the stringers toward the front. you would have to replace a section piece and get the strength of the floor back. that area takes all the brunt of the waves as they enter the tunnel. if the floor has much flex it may crack along the side of the center pod. my 2 cents
Thanks for the advice guys, I didnt think about it strengthening the tops of the tunnels. I'll open it up and see what I can see. From the top it looks and sounds like the area over the tops of the tunnels is still good, maybe I can save that area.
Any other ideas on how to support this thing now that theres no foam ?? Its really flexible now. If I grab one of the sponsones from the front and lift, the whole bow will flex and twist.
you may want to start another thread stating you are working on a Brendella jet and would like some advice you would get more hits from owners or people that have rigged the Brendella's. from what I have found they are kinda their own breed. one man to talk to would be Jak with Black Bear Racing. he races a black Brendella jet in the 8's and is looking to get to the mid 7's and is buddies with James Brendel. I talked with Jak a few times about my v drive one and he's a super nice guy and has done alot of R&d on these hulls. he also goes by ( 1/4 miler ) on here. you want his info let me know I'll pm it to you.
Thanks Sleek, your right Jak is a super nice guy. He already helped me with a few questions and gave me some advice on other things with this one, I just didnt want to bother him again. I always feel bad calling and bugging people with my dumb questions.
i think your hull and centurion and brendella were the same. im not to sure. i looked at my buddys and he has no sub floor. dont rely on the foam to support a deck thats only to keep the coast guard off the boat builders rear for safety. i dont know much about that hull but i think you found the right guy and knows about them. heck if it were me and its not needed then hell with it but make sure there isnt some flaw in the hull and that was the reason for the sub floor. mainly a poor mans fix. good luck sounds like you got it handled . keep the pics posted as the project comes along.
