Need help with trailer LOA

[Norris boat]

just bought a new SX22 and ordered 22 ft hustler trailer with swing away tongue. Can anyone tell me what the LOA will be from the back of the 150 Yamaha to the point where the trailer tongue is swung to the side? I am hoping it fits in a 30 foot barn. Thanks in advance for your help.

It will be close. the swing away tongue will help for sure though.

Can someone explain trailer sizing in general? The one i have came with the boat... So how do i know what size it is? Is it the max boat size that fits? LOA without a boat on it? Something else???
