Boat Rebuild

Hi Shu,


Feel free to comment here bud

Shu how far are you with your rebuild? Would love to come and see what you have done if possible. I’m a complete novice and am looking to learn wherever I can.

To Be warned as i have done this for many people and myself, and allways tell them upfront, the boat is never going to worth anything near to what you spend on the rebuild.

I've long since learned that the work I put into my boats will never be rewarded other than through sheer personal satisfaction and that lekker fuzzy feeling when you're sitting on your work of art on a stretch of water, dreaming about the next boat

The intention is not to sell it but to hand it to my sons in a good condition when they are old enough!

what motor came with the hull

[fishy1969]

No motor Rory...will be on the lookout for one later.

Hi .


See pictures attached of the build progress.Took a old butt cat and transformed it into what i wanted.still not complete but i am almost there.should be ready in about 3 weeks time.with regards to the PU foam, i did a few tests which was very helpfull in making my decision.I used 3 x 500ml plastic containers in which i ran the tests.


1- I poured the PU foam into the container without any lid and allowed it to rise.I poured extra to let it rise above the top of the container.After setting. the extra foam at the top was cut flush to the container and then soaked in water.


2- I measured the exact quantity and poured the PU foam into the container with the lid on,making a hole at the top to allow it to rise.After it cured, it was removed from the container and placed in water.


3- The last test i did not measure exact quantity but did the PU foam pour in 2 parts but with the lid on.After it was cured, i removed it from the container and soaked it in water.


Results:


1- this method proved to be the worst.Once cut, the foam absorbed water about 1 cm into the foam which is bad considering this was a small piece.
2-this proved to be the best method as when i cut the foam open it was abosolutely dry inside.in my belief, the film that is formed around the foam helps prevent water penetration.
3-this method is effective but has some draw backs.because no c utting was done on this piece, it did not absorb any water but i did find that there where gaps between the container and the foam.These gaps when looking at it in the perspective of a hull is not ideal.the gaps will allow water to sit there should water penetrate through the deck/hull.


All in all the 2nd option was the best and i opted to go that route although calculating the quantities required was quite a challenge.In a nutshell, we did all the the bulkheads and stringers,then proceeded to install the deck.after the deck was installed, we cut holes on the deck to each chamber.the foam was then poured in and allowed to rise.We did have to cut a little foam where it pushed up past the hole but this is a small area so im not concerned.


I hope this helps.I will do a full report on the build soon but i am hectic with work and nned some time to compile.Never the less i have attached the pictures.

are you fitting out mounts on

[shu vawda]

Yes Rory.they already fitted.I hope it works out fine.

[Rory mundy]

Just tricky to get engine height right

[shu vawda]

You are quite right.Initially it was a challenge to get the dead rise and the height of the motors right.The boxes where bigger before but before installing i set them on the boat and called Natal power boats out to check.Had to cut them down slightly after.Measured now and its perfect.


Guys reckon that it improves the ride.is this true?

[Visenvryheid]

I fish off a butt with them, asked the skipper what he thought and can't remember exactly what he said but they were a winner. He is a very experienced skipper, spent his whole life on boats and butts. We go to the deep off CT and the ride is a loooooooot better than our little inshore cat, which is not bad at all actually. But wow does that new butt ride well (from a passengers perspective).

[Big B]

Thats a big project, good luck with that.

The next stage was to clean the hull out completely in preparation for the rebuild. Agin messy work but completely necessary.

Evening Fishy1969,
