Hi Cris, yep i was now i am again but this time after i have been busy, Hull is joined and managed to pull the cowl out of the mold, pretty happy so far. Joining the upper and lower half was a pain, but hopefully it will be ok.

Hi all, Chris....cris...kriss....nah only joking! Yep it was wet when i took the photo, should hold though. May even get the top off the mold today ???? i am getting anxious but guess scene it has taken me 5 months to get this far a few more days won't hurt.
Dont worry i will take some pics as soon as the hull is out.

It might be hard but leave it a few days to make sure all the stresses are out the resin. Noting worse than having the thing go and pull now.

Well the hull is out! Started just taking the bolts out from the flange, then the top was loose, so what the hell, the actual hull was in the mold for 3 days already so it should have been cured, Pretty warm here.
Just have to do a few small repairs to the mold but she's basically ready for production.
For those who are interested, Sponson width is 145mm x 195mm deep internally, there is 235mm depth in the middle to the underside of the cowl.

Regards
Mick

Now that is a beaut. What was the final hull weight? And put something like a transmitter or motor in one of the pick so one can really get the feel of the size.

Congrats.

I will get a few more photo's for you all tonight, Pretty sure weight is around the 4-4.5kg mark, but i will certainly check this out too.

Thanks for the coments, Unfortunately i may not be able to get one on the water just yet due to lack of funds, so i need to sell a few to get the ball moving.

Now started on a 1/4 F1 48" build, will start a new thread for that.

Maybe you can work out a good price for a customer in return for some water testing feedback. Might need to do a few adjustments to mold depending on hulls running attitude before you sell too many of them. Just a thought!

Hello again, weighed the hull today, it weighs 6.2kg with bulkhead and transom doubler, may seem like abit heavier than some but bare in mind i don't vac-bagg my hulls.
pictures are of a RCMK SX254 just sitting in the sponson and a 43" Jordo Cat beside it to help in the true size of this beast.
cheers mick

If the transport was not so heavy I would take him up on the offer any time. Mick do you wet your matting before you put it in or do you wet the mold and the place matting and resin again? And your weight is about right 44" cat is about 4kg so 4/44x72 = 6.54kg so your weight is not that far off.

Hey Cobus, no i lay 1 layer of matting in there first, wet it out with resin, when it is all soaked in i use a roller to make sure all the air bubbles are expelled then lay in the next layer of matting and roll it again, this time the resin works it's way thru, once that's done i then do a third layer and repeat the rolling, if it looks a little dry on the third layer i wet out the area's that need it but usually it doesn't require it. I try to strive for the perfect 70/30 mix of Matting to resin ratio.
It may not be the best way but it works for me, afterall i have had no real guidance from any boat builders as they all seem to think Fiberglassing is a Secret and don't want to share their ways.

There is no secret to fiber glass they just want to make money off you in them doing it. I asked because the pictures of the inside of the boat the resin looked very glossy and that normally means to much resin was used. but your method sounds good. Try a lay up in wetting the mat on a piece of glass that way every time you pcik it up to put in the boat excess resin would stay behind. Thus making a lighter boat. Is the whole boat chop strand or do you use woven cloth also? what is the mat layer you are using?

I use chopstrand for the whole boat, it's 225gm, i really don't like plain weave or multidirectional as i fing it is very hard to keep the airbubbles out, chopstrand i have found bends really easily and is alot easier to get the airbubbles out.
Probably seems glossy because i had to rewet the last layer to ensure there is adhesion. I guess i am confortable doing it this was after 15-20 molds i have done,i probably really have gone Vacu-bagging it all as i have a pump but it really doesn't seem worth it with all the extra work to get the mold stronger.
Thanks for the coments, and can understand why it would be lighter.

All the weight sits in the resin. But as my calculation showed it is not that bad. Once she runs you will see if it should have been lighter.
