Especially with lower size/performance boats, be sure to consider depth below deck needed for a drop-in TM tray. Have a "Plan B" for the situation where you discover depth below deck to the hull isn't enough for the tray to fit all the way down. (This has happened many times as a surprise.) Cut the rear portion of the hole first and take out material to get an accurate depth measurement. Work your way forward, and if you run out of depth, you just found where the front edge of the new tray will have to stop. If that makes it not likeable, you can get 1/2 to 1 inch of extra from a neat riser plate made with starboard cut to fit around the lip of the hole with the tray's lip resting on it.
