Have a 40ft building will a 35 executioner fit on a trailer total length with the drives? Might be able to use some angle to help

It depends on the trailer. Boat length + 7 feet is a good number.
You will probably barely squeak in given the number fudging on Fountain lengths.

Some trailers have a really long tongue. Surge brakes usually adds a foot or so vs. EoH brakes. There are a few more threads with info on these variables.

Also, your building may be 40', but you garage door is probably set in 4-10 inches. and wall thickness/posts/beams may affect usable depth. if you try to angle the boat in, you may likely interfere truck bumper with door/wall.

34' lol

as I said before,,you never miss a opportunity to take a cheap shot at Fountain...I am glad to see this time is no different..

why would you come on a Fountain thread on the Fountain forum when its clear you do not think highly of Fountains?

That was BY NO MEANS a cheap shot.
The comment after mine could be construed as such.

I could have spelled it out more, by stating that the swim platform does not count for pushing the transom out 2 feet, so that will help in this conversation; not adding two feet to OAL. But it still wasn't a cheap shot. I've spent plenty of time on Fountains and there are actually two particular models which are on my 'next boat' list.

It's no secret fountains are short put my 38 top gun up against a. 38 fountain and there's 2 feet diff
It's true so why get upset

Fountains "aren't short". They just market differently.
38 Fountain
38 PowerPlay
38 Cigaratte

...have DRASTIC size differences.
It's just marketing chaps.

Which ones ? My GF would love me to get a Express Cruiser

That's one of them.

Bull $hit if it wasnt..
