Desperado 18" 19"

Postby Bill S. » Sat Jun 23, 2018 2:32 pm

Is there anyone out there either building or who has built a Desperado. I need to make up my mind on what power I will use.
should I use I/O power or keep it simple with outboard. I have never built a boat but have owned several in the past. I never have chosen the power only took what came with the boat.
Looking forward to the boat building experience and meeting new people with the same interests. Bill

I am having problems sourcing 3/8'"marine plywood for the side panels on my Desparado. Is 1/2" too heavy or to stiff to use in stead of the 3/8/"
Thanks, Bill

3/8" is stiff enough and hard enough to bend as-is. 1/2" would be really difficult. I don't know what your options are in Nevada. Some folks have had to resort to ordering plywood and having it delivered freight. The downside is you'll probably end up ordering for the whole boat at once. The plywood will likely be the single biggest expense besides your power plant. I drove 3 hours twice to get the plywood for my boat. Have you checked this list?: http://www.glen-l.com/resources/lumber-suppliers.html

Thanks for getting back to me. I really do agree that 1/2" would be tough. I am new in this boat building business bu what about two layers if 1/4". That seems to be easier to handle especially with the bending. What do most of the builders do accomplish their side panels.
I don't want to be a nuasance but I an also having a problem on deciding what thickness transom to use for an 150 hp outboard. The Boat Builders Notebook suggests the transom for outboards over 85 hp should be from 1 3/8" to 2 3/4" thick. I have enough 3/4" for 2 layers and some 1/2" for one layer which would give be 2". Do you think that that would be enough or should I just go ahead and buy another sheet of 3/4". I really do appreciate your input. Thanks, Bill

The entire transom doesn't need to be the full.thickness. Just the motorwell area. At least that's my interpretation and how I built my boat. So depending on the size of your motorwell you should have enough for three thicknesses of 3/4.

Hey Bill,

My boat has a 150 bolted on 1 3/4" thick transom. It is painted but I assume it is plywood.

Two layer of 1/4" should be fine, or a top layer of 1/8" if you can get it, to make 3/8". Take care with frame placement, faring, and clamping the plywood, bending on the thinner material will magnify anything that is off.

Thanks on the transom thickness and it does make sense. My Concern is with the rest of the transom only 3/4" is that enough to handle the torch of a 150 hp outboard ?

I also like the idea of 1 1/4 " with a layer of 1/8" on top. I could do that in mahogany "I think"
Thanks again, Bill

No. Imagine that big hunk of iron bouncing up the boat ramp. Tom

Well I finally got my Desperado on the form. laid d the keel and stem today and it is looking good. I am going to have to stop for about 10 weeks. We are leaving on an RV Caravan and won't't return until the first week of November. I wish now that I hadn't signed up for the trip because this boat building project is really getting interesting. Can't wait to get back.
