Swim platform and side port exhaust

Hi everyone First let me say how impressed I am at how helpful and robust these forums are. I am in the frame install on stringers stage if my barrelback (funally looking almost like a boat shape). I plan to put a swim platform on the transom at the end. Has anyone done this for the barrelback? I ha...

Re: New (sort of) in Annapolis MD

I grew up with my grandparents barrel back, its the boat that i learned to drive a boat on, learned to waterski on, etc. So many good memories with it. When they passed, it went to my cousin (here she is picking it up) http://drpetre.com/boat/boat_project/Welcome_files/shapeimage_2.png restoration h...

New (sort of) in Annapolis MD

I ordered my barrelback 19 plans years ago but did not have any build space yet. I did a 1/8 scale mock up to see how the process works, and have a really cool model from that (still looking for the right R/C parts to make it a R/C model). I have finally moved into a house with an adequate garage in...

Re: Seattle Barrelback progress

Can someone correct what i am sure is improper reasoning:

With the same drivetrain (transmission/prop), going from v6 to v8 does not add more top end speed, just better holeshot/acceleration/pulling power...right?

Re: WHite Oak

I think peter G's logic is in the right place but slightly flawed. I have calculated the BF needed for frames and it is far less than 10% of the boats weight. Just to order rectangles to encompass every frame member of the barrelback 19, the total BF is 55 in 4/4 lumber. Planed to 3/4 thickness and ...

Re: converting from standard inboard to v-drive

Ok, project started. I bought belle isle plans and have started a 1/8th scale proof of concept scale model. Progress can be seen here.

Re: converting from standard inboard to v-drive

Yes! That is very similar to what I want to do! I would probably shift everything forward a bit trading foredeck space for aftdeck as it is a large foredeck. Unfortunately, I want to build the boat, not buy it. Looks like he compensated with a wider aft.

Re: converting from standard inboard to v-drive

in boat design theory- does it matter where the major wieghts in the boat are or where they are in relation to the center of flotation? in other words-if the engine/tranny is moved aft 4-5 feet (calculates to 4059 foot lbs) can this be fully compensated for (in theory) by placing 200 lbs 20 feet ahe...

Re: converting from standard inboard to v-drive

Not looking to go 100, especially with my kids potentially driving this some day! The ultimate goal is to have a classic looking boat that functions much like a newer runabout with an open cockpit design. I envision a multipurpose craft for cruising the lake, skiing, wake boarding, tubing, etc. Woul...

Re: converting from standard inboard to v-drive

Also-from what i understand, changing the shaft angle changes performance characteristics of the boat. Increased angle helps with the acceleration because it keeps the bow down and a shallow angle increases top speed because it uses more of the force for forward motion? Is this true? How much differ...

Re: converting from standard inboard to v-drive

Thank you both for the informative replies. I think i have decided on the belle isle to try this on. My logic being that the lager boat will be less sensitive to weight changes and will allow more wiggle room for enlarging the cockpit. I will certainly look into that tranny-vdrive combo, it looks pr...

converting from standard inboard to v-drive

I am in the planning stages of building a glen-l boat. I grew up going to my grandparents house in PA and cruising the lake, learning to waterski, kneeboard, wake board behind a beautiful 1942 19' century barrel back. I am in love with this boat, unfortunately it was given to my aunt when my grandpa...
