A little bit of grease in the rudder tubes will help keep out the water.
Also, the tops of the rudder tubes are typically above the water line.
At least that is how I typically build mine. This way little or no water
ever gets in via the rudder tubes.

If you're worried about water getting in, put in an automatic bilge pump. It'll detect any dangerous amount of water and turn on, pumping out the water until the ship isn't in any danger. Standard practice in Model Warship Combat, where a little water from rudder tubes is the least of your concerns.

Umi gave good advice. Those're the easiest and cheapest things you can do, and it'll have the most effect. You only need a bilge pump if you're going into combat, seriously heavy seas, or you're on the water for days at a time.

Way to go rye.

I had those same problems with the under 30" PT's. If you blow up my postings you will see the completed frames & keel of a 85' ASR boat designed by Sparkman & Stephens for the USN in the mid 40's. It is 5'. Was 2 Packard PT engines with 1 twin 50 cal. in the stern deck.

All small boats are deck assembled, Then I cut and brace 1 or 2 flat raised deck hatches to make life fun. The 8' boat has a rudder access hole under the rear 20 mm gun deck plate.

Hello Rye,

In my opinion, if i were to run a 5' PT boat, i would use 3 Astroflight 25's or 40's direct drive. They are very reliable motors and will easily run your boat. The motors have a variable voltage range so that you can decide how fast the boat will go full throttle by X amount of volts added. (see astroflight motor specs)

I am overhauling a Dauntless (4' 1.5"), in which the hull is based on a PT boat design. I will be running it on (2 )Astroflight 25's with (2) Astroflight Harbor Master speed controls. (That speed control is supposed to be very good and also has reverse) That will give Dauntless plenty of power to plane out and look very scale when underway.

The original Dauntless ran on (2) Packard PT boat engines and was 66' long topping out at 40+ knots.

PT boats ran on (3) Packard engines at 78-80 something feet long and topped out around 40 knots.

Hope this helps.

Best of luck.

-Rich.

Exchange rate & shipping should be about 600 to $ 700.

For a SEMI-KIT ?????.......I think, no way.

BUY IT NOW!!!!!!!!!! Go for the best price.
I built and run it with kids. A LARGE Pittman 12 volt motor, 12 volt gell cell, Octura prop# 2.8 is a plastic one for a .187" shaft size, will move out with a churning mound of water at the stern. It has a 5" pitch. The tug PUSHES a huge bubbling bow wave.
Look on the bottom shelf under the PTB. That is the Amsterdam compared to a 8' ptb.

If anuone ever needs ACCURATE plans of PTB try to buy ....Al Ross Coastal Defense Forces...... They are perfect for scaling up and the shape is perfect. NO modifiying frames or spacing.
