You need a boat with working depth charges 🤣

I have been out with my boats a couple of times and someone has turned up with a submarine. They have put it into the water whilst I have been running around with a 10cc Nitro boat and one with a 26cc PT109 and I have had to come off of the water as it has gone under water and not knowing where it was and not wanting to maybe damaging the sub. That really worried me.

There are partial plans available to download at NARA RG 26. Look up by date, I found them in the 1930-39 section.
All as built, main deck and and out board and inboard profiles. I did not see a station plan.
There is always USCG Museum NW. Their cost is minimal, if not Floating Drydock.

Greetings! My offer is this. If anyone has 378' WHEC Secretary or Hero Class Coast Guard Plans, I will have for trade plans to every US Battleship, Three IJN Battleships (Yes! Yamato), Italian and French Battlships Littorio and Richelieu also Bismark. HMS Renown, Nelson and Hood, Cruisers IJN Atago, and Brooklyn Light Cruiser also Indianapolis. One or more are yours. I can of course purchase a set, but in my lifetime, I do not have the desire to build all of these, or time in my life to do so. I have planned my OPUS to be a 378' WHEC as it was in 2014 before retirement from service. So, anyone who wants what I have here, also let me know. Picking up this stash of plans Saturday, but I am impatient and thought I would give you all something to read and ponder.

Have a Great weekend, I hope everywhere your weather is perfect for our hobby.
