As far as where to look at hulls and hardware - there are a number of options depending on what sort of hull design you prefer and many ways to set up drives etc to make her move. Some reputable companies I would recommend include Bonzisports.com, Enforcerrcboats.com, insaneboats.com, zippkits.com, gizmomotors.com to name a few. Certainly let us know if theres something specific you are thinking about and maybe we can help you track it down too (just responded to your stuffing tube block question).
