Seaducer S mono SAW build.

Hopefully Doug Smock is still around somewhere lol. I recently got the itch to go fast again and have been out of boats for a while doing other things. I noticed seaducer was offering a 42 inch hull intended for electric use and would like to know if anyone else has built one and if they were as stable and consistent as the nitro hull counterparts.

You should probably ask Jerry directly, but to my knowledge the new electric hulls have the same bottom as the nitro hulls with a revised top that is easier to tape. In my humble opinion Seaducers are great nitro and gas SAW hulls, but it is very difficult to make them fast with a heavier FE build. If you can keep the build lite then you have a better shot of running free. From my own testing other hulls will run faster with equal power.

Thanks Tyler. Jerry did confirm that the 42 inch hull is the same as the 60-80 nitro hull with a different top deck. My plan was to shoehorn a setup capable of around 15k watts in one and see what it would do. Would make for a good laugh if nothing else provided the hull would take it.

Ask Jerry to reinforce the seams as much as he can and perhaps add one or two additional layers of material to beef it up. I would highly recommend stiffening the nose with 3lb 2-part foam. This will reduce the possibility of caving in the top deck and splitting at the seams. And of course the foam keeps the boat afloat in case of a crash which will happen.

I asked Jerry to add a ton of reinforcement and let him know what it was going to be put through and what was going in it, are you referring to the expanding foam used for basically spray in insulation that expands?

[RaceMechaniX]

Don't get the spray in insulation you find at Home Depot. You want a 2-part mix foam like this: http://www.uscomposites.com/foam.html
I prefer the 4lb over the 2lb, but in a large mono it can be a lot of weight up front so 2lb might be better.

Could use that and make a backbone from 1/8 ply or carbon fiber to join the deck to the hull length wise up front and the foam would make it rigid by not allowing it to bow to one side or the other.

[RaceMechaniX]

The "pro tip" I have for 2-part foam is to mix small batches (3-4oz) and allow each pour to cure for 30 min before starting the next. I roll the hull from side to side so the liquid foam covers the most surface area before it starts to expand. If you have a junk hull or something else to test first I would highly recommend practicing on something that is disposable.

How much expansion force will it apply to the hull, I know some act differently than others and may cause it to bulge and some wouldn?t.

[RaceMechaniX]

It will cause the hull to bulge if you use too much at one time. Hence small batches.
