I've been looking for a lapstrake trailerable cutter for quite awhile and discovered the Whisstock site. I really like the 20 foot design 123. I have a couple of quesions of course. In looking at some of the data availale the ply esimate is for 29 sheets of 9mm ply but then suggests 30 sheets of 12mm ply. Is it 9mm or 12mm hull? I would prefer a gaff cutter but would you mind if I include a topsail? Always liked the look of a topsail.

Hi Ben ... the hull is 9mm ply – the total with 12mm is an error which I will go and fix. Sorry for the confusion.

You can rig a topsail. Probably the best way would be to use a jack topsail. That is a topsail incorporating a spar on the luff, which is hauled up the mast with the topsail to extend the height of the mast while the topsail is set.

Other options are a traditional topmast or extending the mainmast so that it is long enough to set a topsail. Both these are perfectly valid but they do add quite a bit of top hamper and top weight all the time. And you would need additional rigging and so on.

The advantage of the jack topsail is that the extra weight is only aloft when the sail is in use, and no extra standing rigging is required. It is slightly more awkward to set however. I guess there's no such thing as a free lunch......

Hope this helps. Glad that you like the design. George

Sir, thanks for the quick reply. The 20' cutter is a very pretty boat and the lapstrake design has always appealed to me. I would be using a 4 berth layout but would only utilize the quarter berths for sleeping. The rest would be devoted to the galley, a writing, chart, dinner table, a force 10 kerosene heater I have and as much storage as possible. I have a nice little 8hp yanmar that has been looking for the proper ship and I think this might be it. I live in the Great Lakes area and have a planed voyage for a trip through the intercoastal waterway and into the Florida Keys for a summer of exploration. One other thing I would like to explore is the possibility of minimizing cabin size as much as practical and maximizing deck area. I realize it is counter to most thoughts on the matter but my father taught me that real men stand on deck and the cabin was for sitting or laying down (ha ha). Any thoughts you could give me on this matter would be appreciated.

I have a lot of sympathy with your father! I was brought up the same way.

We sailed a 40' Lee Bawley Gaff Topsail Cutter (named Dawn), with a hand-start petrol/paraffin (gas/kerosene) Kelvin engine installed on the angle (so the prop was to one side of the sternpost). This produced pretty much zero handleability in any wind at all, but it was vaguely useful (if it would start, which was only fifty-fifty), in calm weather.

She had a 15' bowsprit and the boom overhung the stern by about 6'. Eventually, after several near misses my father cut about 8' off the boom - which was a good move. I well remember when I was about 8 years old, running downwind in a gale in the North Sea, I was handed the wheel with instructions to "sail her small", while my father stood on the boom to reeve a reef pennant. I managed 3 standing gybes while he miraculously clung on and finally jumped back on deck. I reckon this might have been the deciding moment for chopping 8' off the boom!

With no guardrails, as a kid I was attached to a rope so that if I fell overboard, my parents could haul me back aboard. I never did -- I reserved that privilege for many years later on a cold dark night in a similar gale in the English Channel ....

Anyway, you can reduce the cabin as much as you like. I can give you a set of offsets basically for a flush deck over the whole hull. Then you can cut the cabin in at any point you wish. You may have to do a bit of lofting to get things right, but basically there is no problem. I don't know if you are thinking of making the cabin shorter – or narrower – or lower – or any mixture of these three?

There is a lot to be said for a neat little boat with the sort of arrangement you are envisaging.

Best regards --- George

I'm looking forward to receiving the plans for the 20' cutter and I would appreciate the additional information for the smaller cabin. I've tried to order the download but because of an existing paypal account it will not let me pay any other way and I didn't want to use the paypal account. Anyway the funds will be on their way this week for a CD version and I look forward to looking over this little craft in greater detail....Thanks

Thank you. I look forward to sending you the CD. I will also create the basic flush deck offsets, from which you will be able to find the intersection of a smaller cabin. I shall be interested to see how she turns out.

Best regards -- George

One last question, I'm assuming that the cockpit can be built for self draining, I would be setting it up as a blue water cockpit and just wanted to make sure I could do so. The cabin as I said before would be minimized as much as practical on all dimensions. Befor I do anything though I'll check with you and make sure it would meet with your approval. Thanks again......

The cockpit is watertight and self-draining -- no worries! George

Just wondering if there are any pictures of a completed design 123?

Hi Sam

Unfortunately we don't have any photos at all of this design. We had a nice set of the first boat built but we lost most of our photos in relocating to the USA some years ago (this was just as we were starting to make a website) and we have been painfully building them up ever since.

We have been very lucky as the boats change hands, often the new owners have questions, and then I can ask for photos! Hasn't happened with this design yet, though I saw that one of them was for sale about a year ago.
