Das Boot- the other variant

The drawings are skewed due to the nature of the iPad and the sheets placed on the bed but they give a rough idea of the other variant to this one:



Situation report is that there is a trickle of money coming in tomorrow and I’m ordering the first wood [irrespective of the hull variant, as the yard is not cutting it], a mate here is ready to move today on our preparations for that delivery [he’s gone to get some bits and pieces now], the only real issue is the big one – both designs are workable but practical considerations have kicked in, which are suggesting we proceed as below.

Delays till now

Mark 1 was 2/3 built and without going too far into my circumstances – the cash suddenly took a hit. There was also the problem of defeating our weather up here.  Circumstances changed, the financial hit eased up in 2017 but that’s when the heart attack struck.

Issue now, in May/June 2020, is that the health and finances are iffy but the big plus is I have all the tools, much of the epoxy and bits and pieces, the glass matting, plus the use of the yard for some time and a second pair of hands helping me with the heavy lifting.

Decision time

The rig being common to both, the issue is the hull form. The mono is nice for sailing but in the big seas, I’m a bit uneasy about the 3/4 inch glassed skin and overall weight, esp. of the ballast, plus the outboard motor rating.

Plus haulage firms will not take that length boat above five tons without going into a whole new price bracket.  The N1 upside of the mono is the way she bounces back up from a knockdown and mine certainly will – her angle of vanishing stability exceeds ocean ratings.  Against that is my age and discomfort on such a cramped boat.  Plus prejudice in the area against catamarans.

The cat is vastly easier for us to build.  We have our mobile shed to go over our work, the cat hull fits down the middle, the actual joinery is a piece of cake, with walls being the main frames and secondary frames put in later – we’ve just been going over how it is done some minutes ago.

The main downside of the cat is obviously flipping at sea, unlikely but still possible, which requires using the dinghy as a tugboat.  She is also 19 feet wide, which involves removing the tied beams to enter the canal system [hulls secured side by side]. To even get to the canal system though, the cat [back at 6’10” again] has 1’4″ draft [laden], so she’s not going to ground where we plan going. Her airdraft, deconstructed, is 5’9″, which means she goes on any canal.

Why would I go mono?  Well the mono is a lovely boat, a proper yacht, plus she’s far more accepted in the north.  But as we sorted our plan this morning for tomorrow, it became apparent that the cat was far more practical for this build in this yard. An example is that, with two levers and four men, she can be turned upside down and right way up quite easily.  That makes the glassing and painting of the bottom way easier.

Against that is always the EU, surveyors and insurance firms who panic when they know the specs, even though she has more structural overkill than the mono.

That’s the state of play.  I feel more comfortable with the cat, I know how she operates, I’ve sailed them in largish seas of 15+ feet and they slice nicely, not so great in light weather and flat seas.

Decision day is tomorrow.

    Do you expect to go out like a Viking? You know, your pals put your body aboard the boat, set it alight, and push it out onto the ebb tide?

    At least no bastard would play “My Way”.

    We’ve started, just upstairs for a coffee. No turning back.

    The point which decided me involves going back to the other post and looking at the hull profile again. In that keel, admittedly distributed over 34 feet, is 1.5 tonnes of sand ballast in 15kg bags, plus 1000 litres of drinking water in 10L containers.

    With the boat constantly at 15 to 20 degrees, falling off waves etc., even epoxied and bolted in, I just couldn’t rely on that strain.

    The cat has a different issue of twist in the beams and frame and the damage would be cracked beams. Not as immediately life threatening as a rift underwater.
