...by building another plywood one

It was a nice day outside so I decided to pick up where I left off last fall on a kayak which I boastfully claim as my own design. I had the station moulds left over from a Tursiops and decided to recut them to produce a new design. It had to be a smaller boat since obviously there's no way to recut them bigger. Fortunately, Tursiops is a very beamy design so I could still get plenty of width for stability. Over the winter I drew up a chined boat less beamy, shallower and a bit closer to the water, moved the chine and sheer inboard and lower, redrew the bow and stern while I was at it and got a start on building.

To get the sheer looking right I ended up just nailing a batten to the moulds in a fair curve that looked about right, which revealed a few errors in the table of offsets.

Here the side panel is tacked into place to be traced along the batten.

Teddy scrutinizes dad's work, and voices serious reservations as to the competence of the builder

That cat isn't going to want to sit there when you get done!
:eek:

Looks like it was a nice day up your way. Nasty and cold down here :(

Are you going to have it ready for the Victoria woodie fest?

Dependent on time available, I might start a Point Bennet in june. Downloaded the plans and have been wisfully looking over them ever since.

This new dezn of yours, does it have the flat keel panel of your Tursops?

Yes, it has a flat keel panel as with Tursiops, a feature I really like, as well as a doug fir 1X1 strip for a backbone which runs the full length of the boat on the inside. Tursiops called for only a stem and stern peice attatched to either end of the keel panel, but I found it easier to just use one long 16 foot length of fir and run it uninterupted the whole length. It's being built out of cheapo luan, quarter inch on the bottom and 1/8 inch on the sides and deck. If I like it maybe I'll build another out of good wood. I've also had thoughts of a strip plank version with the hard corners taken out of the chines. Haven't decided what the deck will look like yet. I'll wait till the hull is glued up and taken off the strong back.

True story: Cats HATE it when their feet get epoxified. Serves 'em right, tho... :D

The panels ended up looking like this

Station moulds are removed and plywood frames added. They will be cut for the as yet undecided deck after gluing and removing from the strongback

Not much gets past Teddy. He inspects garbage bag plastic placed over the stem and stern moulds to keep epoxy from sticking.

Max wonders if there will be full sitting headroom once the panels go on. Apparently this is very important to cats when it comes to kayaks

Max has to hustle or Teddy will clean up

I really prefer the hard chine and gunwales because when you have to do a wet re-entry, it is nice to have something to get your hooks around, otherwise its like trying to hang on to a floppy trout!

Orange cats are fatter, more laid back, have a sweet tooth. Ours likes people food more than his own.
