Skagit 20 - Alaskan Bulkhead

The extension looks great! Nice work!

....middle (3) platform sections (1/4" thick) ready for gluing/filletting/tabbing.

That looks pretty slick.
Glad to see you made it onto the new forum system

Here's the port side outer shell, lower half, glued in place. Next,
some more putty and tabbing. With any luck the seam won't be visible. The extra length starts to give the boat a real, PT boat look, minus the torpedos.

That is very nice work, I can finally see where you are going with your design.

[Skagit Hideaway]

Thanks Lyle,

I think it is going to actually work.

That is interesting for sure.
How did you make that radius on the corner ?

[Skagit Hideaway]

Helmar,

I contact cemented a plastic sheet over the Port aft corner of the boat and then laminated over that. The cured laminate pulls right off the plastic - original Skagit 20 stern corner radius The contact cement comes off without too much trouble. See post #38. I hope everything is on right, cause it isn't coming off, ever. Modern, low viscosity resins really soak into the old laminate surfaces.

Port, outside top piece almost ready to clamp/glue in. The outside ledge is still a little high - thus the gap at the corner curve. Edited out some distraction in the background.

More sanding, glassing, fairing to do on this side...

[Frederic Lynes]

Looks great! A pair of Evinrude V8 300s would look great on there!

[Helmar]

That is getting a good glassing for sure.
It will be nice to see more of it when its in primer...Good job !!

I gotta say, every time I open this thread it always amazes me...nice work on the addition.

[McSkagit Tim Jones]

I finally got a chance to read through most of this thread. Ambitious for sure. Nice designs and workmanship. The key issue in my opinion and experience is weight. Weight is always an issue in small planing hull boats.

My Skagit 31 Saratogan became overweight when I added diesel engines, picking up almost 1000 pounds from the engines alone. Then I added more fuel capacity, the electric drive system and battery bank to power them, another 900 pounds. Well the boat carries it all pretty well, but some of the useful payload (people and gear) has been used up with battery weight and fuel. Looking at the original design, designer Howard Roberts was spot on with his weight calculations for engine placement, weight, etc.

Need to be careful modifying these older boats. The 56 Skagit 20 was (is) already heavy; heavier than the later models. The glass weight alone for the superstructure (what you call the Alaskan Bulkhead) is going to be considerable. Maybe Lexan for the side windows.....much lighter.

Look forward to seeing this boat out on the waterways. Twin 90's more than enough power, especially with the hull extension....

Cheers,
