Hi Everyone
I am new to this forum and quite new to model boat building.  I have just finished building a plastic hulled Banchert and would like some advice.  Last week I took the boat on its shake-down cruse and the boat got swamped.  Initially it had a 15^o list to starboard which I dealt with some fishing weights, the lake is situated right on the seafront at New Brighton and the 20mph on shore wind mad the water quite choppy and water got into the hull.  Most of this water came in through the joint between the deck and the superstructure.  Has anyone any suggestions as to how I can make a seal between the two surfaces and maintain my access to the battery, controller and switches?

Welcome to the forum.

How much coaming (upstand) have you got between the deck and insides of the superstructure?.

toes theres about a 1/4'' lip.. but on mine its a loose fit so
 adding a taller combing should'nt be a problem

[malcolmfrary]

Always a good idea to make sure that the join between coaming and deck is watertight.  Dont ask me how I know this.
How "free" are the freeing ports?  Its always a good idea to give any water that gets onto the deck the chance to go back to the outside rather than down the inside.

Looking at the photo, the tug is naturally top heavy with its tall funnel and mast, so with a cross wind like that and choppy waters the model could be expected to list badly and take in water. The Banckert is quite a small model tug as well which doesn't help in such conditions. It looks like a very nicely made first RC boat, however! Well done.

I sealed around the outside of the coaming with clear bathroom sealer.

Thanks for all your posts, however I am not clear as to what you mean by ‘combing’, is it the small ridge moulded into the deck around the access ports?  Does one simply build a wooden wall around the access inside the superstructure?

Also ‘freeing ports’ I guess these are holes in the gunwale to allow water to flow back into the lake.  I did see these on a couple of pictures of the Banckert I saw, however there were no instruction in the kit on how to achieve these through two layers of plastic and no parts included to construct them.

Thank you for your kind comments polobeer it has been hard building the model but still a joy.  I particularly enjoyed finding solutions to the various problems I encountered, like the deck not fitting the hull.

Hi Degs
Yes the combing is the raised piece around the deck opening that your superstructure fits over. If it is possible raise this.

You will definitely need the freeing ports in the sort of water you are sailing in. The easiest way to do these is to mark out the opening with the bottom edge level with the deck, then drill a series of holes along your lines, close together, and then complete the job with a fine file.

You should end up with something like mine , below.

My first tug was a Banckert, and I also had probs with the deck/hull join.

Freeing ports, I didnt do any but in hindsight I suggest you drill through both layers of plastic and fix in a length of plastic or brass tube, or, even better, cut out square holes to suit a pce of square plastic tube.

boatmadman,
There is a dictionary of technical (and not so technical!) terms in the Forum.

This may help you and others.

Roger,

Now I am confused - easy I know- what technical or not so technical term did I get wrong? 

[Roger in France]

Sorry, I meant "degs"....and others "combing" or "coaming" and "freeing ports".

Thank you Boatmadman that looks very useful / interesting, I have down loaded it for future reference.
