Puffer question
« on: October 21, 2012, 08:58:33 pm »

Re: Caldercraft Northlight Puffer

I’m just about to cut out the washports in the hull. Reality differs somewhat from the plan:



The deck level within the hull is lower than implied by the drawing which means that I will have to cut  into the upper rubbing strake to fit the covers.

My question is: Will working washports be counter-productive? It seems to me that they will make it easier for water to get in (40mm waves). Conversely, if water gets over the gunwales (60mm waves), it would be good for it to have exit routes.

Could you just place the cover on the hull without cutting, and seal it down ?

Hi Ken

Yes, that's the way the model is designed to be built. My problem is that, where possible, I like to make things work. It will be a bit fiddly making the hinges and getting the covers to swing shut - hence my question!

If you have the deck showing through the open washports centre line, then you do indeed have a problem.

The upper surface of the deck is level with the upper edge of the topmost rubbing strake. Cutting the washports is no problem; fitting the covers is a different matter. Obviously on a full sized vessel these would be under manual control and could be secured in the closed position. With a model, one would hope that rolling motion would cause the covers to act in a valve like fashion - but they would still be pretty leaky.

I know that the sensible thing is to not cut the washports - but the trouble is I'm not sensible!
