Summer Kyle

I believe that Summer Kyle was designed in the mid 1990's: not so long ago. Wide bodied boats with the need for more HP were relatively common in those times.

 

What I was mentioning is what used to be called composite before FRP; wood shell planking over metal frames. Nowadays the metal frames would be CNC, thereby reducing the need for a special jig.

There are a lot of different approaches, but the combination of materials can be very cost effective and structurally efficient.

I did a presentation on this at the CPBS in 2012 - the videos are linked from the post on the 2012 CPBS.

Ok, I follow, metal frames.

 

Of course, but the hull design is far more in keeping with the vogue of a much earlier era.

 

The stile is from the 1930ties, the tunnel is developed from the Atkin boats, designed for a customer in 1996 me thinks, I don't follow with the "need for more HP". The suggested engine is 170 HP. One of the first built used a Cummins 6b instead of the yanmar 170 suggested and the owner states it was an overkill.
More HP would do little good in this boat, even when a Cummis 6B over a Yanmar 4 is a bloody good decision. I would go for a JohnDeer 6068 if it fits anything more is a waste of fuel.

 

Not saying it needs more hp, the point was that the boat could perform with lower power than more modern (wider) boats would require. Not a bad thing with today's fuel price.

 

Gotcha!

 

One thing that might be an issue is water slapping around in that aft tunnel feature, riding at anchor. Keeping people awake possibly. But a lot of boats have noise producing surfaces that are annoying. In the case of alloy, they all sound like a barrel with marbles rolling around !

 

Mmm, you have a point ... perhaps one could stuff a bale of hay or an old pillow in there?

 

Or build in GRP/PVC foam sandwich, which makes a quieter boat than most.
