im about 3/4 the way though buidling a mould for 65" deep v. i used dwr9's (doug) plans just ask him to email them. or search the forums for other plans.im using the woody plans to make a male mould to run off a glass hull... is easy

if you take the plans to a printshop they will be able to scale them up or down. thats what i did for mine. ( although the nose of the boat wouldnt fit together when i built it so ive fabricated one with body filler...) oh what fun

The first link will take you to a plug and mold build of the same boat you are getting ready to tackle in a 50" version. The second is another mold build but of a different technique. Both are boats that could be reproduced again and again. The last link is a step by step guide to how I build the actual fiberglass hulls from these molds....at least the deep V. Hope you have some time on your hands

just curious.. what engine are you using exactly?I know you said its a 49cc but is it air cooled/ water cooled?Is it out of a minimoto? in my hull i stuck my weedy motor in there to get an idea how it would fit i still had plenty of real estate. the motor had shrouds and all on it. im planning on using a polini clone from aBANSHEE SHOpocket bike. i did some research on pocketbike forums and apparently they are a pretty reliable and powerful motor for a chinese clone.

I suppose you're not very clear on your intentions with this project. Do you just want a big boat for yourself, or are you planning on offering these to the public?
Easy, sort of...if you've done this before. I come from a strong autobody and fiberglass repair backgroud so these boats may be a little easier for me, however they do take LOTS of time. Making a perfectly smooth and lump/bump free plug is only the beginning. Molding and proper mold prep is what separates the men from the boys. Good quality molds are heavy, well constructed with a MIRROR finish and will last for years of use. Nobody wants to buy a boat that has imperfections in it. Block sanded and hours of polishing are the only way to make them worth building from. Even light scratches in a mold will transfer to the part. If you have to do more work to a completed hull AFTER it comes out of the mold, you didn't spend enough time on either your plug finishing or your mold prep. Any part should come out looking like it's going to look for the customer, otherwise you're just creating more unnecessary work for yourself. I do have one mold that has light scratches in the gelcoat, but I don't care since I paint prep that particular hull due to the seamless design anyway so it dosent matter. The other one, yeah, flawless finishes from the mold direct to the buyer.
Why an I saying all this? Because of the size of what you're about to tackle. I know how much building time Ihave in these molds and the seemingly countless hours preparing the molds to get them right. 80" is huge, and will require LOTS of time and a decent amount of cost associated with it. Several members here such as Dana and Mart that build hulls themselves also will back this up. Not trying to scare you about this, just would have to have a project go by the way side because somebody didn't realize the amount of work and time required.
On the other hand, I'm a teacher. I teach students HOWto do this and give them the same speech. It tends to give them that "I CAN TO do that!" attitude and they tackle it with excitement, especially when it comes to the end. I wish you luck with your research into this project and I only hope share your expereinces with it here in the forums. Don't think anybody has made any 80" build threads yet!

there are no plans for a mold
if you just want one boat the best way to build it is to download plans then print them the size you want out onto paper and trace the patterns onto plywood (approx 1/8" and 1/4" thickness) and cut it out and assemble the boat, starting with the frames and then the skins, using epoxy to bond it together and fiberglass tape on some crucial joins, when done seal wood with epoxy and then paint boat then your done
there is no need to build a mold and make the hull out of fibreglass, it is much easier and cheaper to build a hull from wood unless you are making multiple hulls then fiberglass is the way to do it

OK, I'll play one last time......
There are NO specific "plans" on HOWTOMAKEAMOLD, only explanations and instructions. However there ARE plans available for building a mono hull. The plans only give you a parts cut out drawingsm however NO directions on how to assemble it. There are multiple build threads here in RCU that many different members have made that will show you how to do it......if that's what you're asking for.
***edit*** Ah Jake, you already beat me to it! Suppose I just can't type as fast as you do!
