just wondering how many ppl have made new hulls. How long did they take to build and what sort of money was spent? Did you go buy the plans exactly or did you change a few things and how well did it go?
Without actually sitting down and working out everything, here is a basic run down for a similar design.
Plywood sheets (4) 2500mm x 1200mm Gaboon $200 Plywood sheets (3) 2400mm x 1200mm Gaboon $150 1 sheet of 50mm Foam 2400mm x 1200mm $ 50 Epoxy Resin (8 litres) $300 Fibreglass tapes, fillers & glue additive $100 Western Red Cedar (gunnels, stringers etc)$ 80 Other bits and pieces, fasteners $100 (guess)
This will allow you build a set of hulls, you should also budget for a timber preserver or everdure type coating, undercoat, top coat.
There would probably (given your location) be the need to build a deck jig (very easy)I made mine from a disused table tennis table (cost $0).
Obviously plans would need to be purchased also. I'm not sure i've seen mosquito plans of late, to know what changes are outlined, but a couple of things on my boat I've done, under advice from other home builders, which I guess can be incorporated on the mossie, are to build the tramp tracks into the hull, and build in the chainplates.
A site worth just having a look at is www dot geocities dot com/phillbrander, and have a look under taipan/tortured ply construction.
Last but not least is time, I couldn't honestly say how much time I've spent building, but the end result will be worth it. If you have time to put into it, the average weekender could probably have built in a couple of months. Mines taken a lot longer than that, but mainly due to work committments. But it is a very rewarding journey.

I'm assuming the mossie uses one, all it is, is a long table basically with the finished shape of the deck cut-out, the hull is steamed and pushed into it to take shape, the hull remains in the jig while all the internals are fitted. I'll try and find a photo.

the 3mm ply 6 sheats 2440 x 1220 for my boat cost $156 from construction plwood in airportwest victoria.
4ltr west resin $82 slow hardener $30 west pump set $35 from saint gobain in nth melbourne
foam 3 sheets from styrapak in somerton $60 plans from the assosiation cost $90 and include three diferent hull shapes, and a step by step guide to building a boat put together by Phill Pearce of south australia. my boat is verry close to the Phil Pearce shape only lease rake on the transom and i have used 3mm ply instead of 4mm.
Is that $156 for the 6 sheets, wow that is cheap! I got my 4 2500mm long 4mm sheets from Boatcraft Pacific in Queensland, would have to look back to see the actual cost of the sheets, but I paid $60.00 freight. I bought 2500mm sheets as to only have the one join in the hull sides.
I have to ask in regards to your foam, what size sheets were they? Were they the white styrene foam or the denser blue coloured foam?
Also the mosquito plans you say have three different shapes, are they based on like a fay hull, a boyer hull and the pearce hull?
What stage is your boat at? how has the 3mm ply formed in terms of where the frames are, I mean not too many rises and falls in the hull skin? I know the A class were built with 3mm and didn't have many problems so there shouldn't be any reason you have.
Keep us posted, I'm very interested in homebuilt boats.

had to put three skarf joints in it, the last one only 150mm. the foam is white polystyren coated in resin. the three shapes one is the original plans no rocker and this shape is not recomended. the ones drawn up by Phill Pearce are based on the Lane hulls built in south australia from about 1991. the other one was drawn up by Ken Lott in about 1985 both drawings have a lot of rocker and verry little seperats these two drawings. at this stage one hull is ready for decks, and the other will be going into the deck jig this week. the frames havent distorted the shape at all, the only place that is out of shape is where i have a skarf joint in the cedar, i dont think it will be to visable when the decks are on, as it dosent look the best.
I always thought when people spoke of Lane hulls, they were refering to Gary Lane of Warrnambool, he could build a fairly mean mozzie as well. Legend has it, he would Mr.Sheen his hulls before every race.

sorry attachment dosent work, it was a picture of the hull in the deck jig. John Lane is the Lane refered to in Lane hulls. Gary Lane of Warnambool uses a Carter boat I belive. I started to skarf the ply wood in May this year and used the farst hardener 205. As it is cold here in winter. the harest part to find was the ceder. the stuff i got isnt verry good.
I have taken the plunge and decided to build a new set of hull for my old mossie. I weighted it the other day and my dear little mossie turned out to be a porker. 76kg base weight. Too much to strip out so I ordered the plans and started looking for gaboon marine ply. Well you should see the faces of the hardware stores around Hervey Bay, then I remembered your reference to Boatcraft Pacific in Brisbane. Thanks.
4 sheets of 2440x1220 gaboon $161 + freight (6=$241) Can't get 2500 lengths so it's another scarf joint for me.
Any comments are welcome regarding the building of new hulls from any mossie sailers. I'm still trying to get my head around which shape to go with and the pros and cons for each.
My goal is to have a competitive boat by the next nationals. (Well the boat might be competitive, it's the driver I'm worried about).
There is only one shape worth going with and that is the shape of the current foam boats buit from the Russell Denholm mould (often called Fay boats). There is also the mould that Phil Bovis has (Bob Wilson's boat), but it's not much different in the water (the deck looks different).
Would it be in the class's interest, seeing as there seems to be a fair bit of interest in homebuilding in recent times, for the association to investigate making the lines and stations of these newer designs available with the plan set. It would seem that nobody would now build to the original specs, so that is one that could possibly be not included with future plan sets, perhaps archived for historical purposes, and perhaps look at the other two, to see whether they are still suitable to be included.
Just a thought.

Question. With the templetes and measuring tolerances I recieved from the National Assoc. Do the newer fiberglass boats meet these tolerances/design or is their a whole different set of tolerances.
What Im trying to get to is if I build a wooden mossie and have two sailors of the same ability would it be a close race or would the design of the wooden boat be too slow
Just a quick note, started looking at the fay fibreglass hulls, they're near the $7500- mark. Starting to talk serious money, hence the option of the ply.
If someone could supply dimensions of their fay hull, it could help all homebuilders like me to know where adjustments can be made from the original plans.
The glass boats would have to fit within the tolerences. I know that if you buy taipan hulls from the mould, they do not need to be measured, as they obviously can't be changed and are deemed to have been measured, same with their boards and rudders.
Building a timber boat, most certainly doesn't put you out of race against glass boats, again the Taipan is an excellent example of this. However obviously whats deemed to be a faster shape would be the way to go, but whether the rocker measurements can be made available would be the next hurdle.
Its been said on here a few times, but as far as I can see there are three different hull shapes in the top three at the most recent nationals. 1st Bob Wilson with the Bovis Hulls, Angry Dragon with a Boyer and Tim with a Faye/Denholm. It has been stated, but again I wonder why, the Boyer hulls are not given more credit, the results are louder than words.

The glass boats would be built within the tolerances, but theres a variation in the hulls shapes, mostly in terms of the amount of rocker I believe, they, along with the three different hull shapes shown in the plans, would all fit within the tolerances, including the original design, but have varying amount of rocker and would also produce various amonuts of hull volume.
Some have said the Boyer hulls don't have enough rocker in the hulls, but like I said the results are on the board. Its said that the Faye and Bovis hulls have the correct amount or seem to be the fastest shapes, but neither the Faye, Bovis or Boyer hulls shapes are available to build in timber, as such the glass versions are at the front row at the Nationals.
This is only my take on the situation, I've never sailed a Faye, Bovis or Boyer hull, only the original. So someone else with more experience in the varied hull shape can probably give a better answer.
