F-22 Factory News - July, 2017
Quite a few changes and developments in our factory the past month, with a new heated infusion booth
as can be seen at back in below photo. This will help double production as until now we only had the
heated Gelcoat Booth, which meant we could not gelcoat and infuse resin at the same time. This was
too slow, so we worked over several weekends and built the insulated booth from steel faced foam
panels, just in time for winter here.
Hull #234 and deck can also be seen above being fitted out, and should be shipped soon. The
other major improvement has been a new interior mold (at left and red) which will replace 6
has been optimized compared to the original interior molds, and
this should greatly speed
But for the last few months it has done the opposite as main hull mold could not be used while the
interior mold was being made, considerably delaying production. However, now that interior had
been finalized and perfected, it was a mold that just had to be done. But it will pay off once in use,
with a much faster production rate, and a better and slightly lighter interior. It was the last major
mold to be made, and while not the largest it was by far the most complex, and difficult to make.
As a result the extra expense and time required has made the past few months very tough.
We are only a small company, and self financed, to keep all design aspects as they should be, with
no unwarranted compromises. The F-22 has always been a 'pay as we go' project, with no major
financing involved, so hence progress has always been governed by the available funds. But we
have at least always had the freedom to try and test many new things.
Update July 25 - the first full interior molding just made and and being trial fitted to boat. The offset
centerboard case slot can be seen on left while the overall perfect fit, molded hatches, and now built
in battery box will save days.
I have never been a big user of large interior moldings, particularly when they are also used to line the
hull, as they can add too much weight. Makes it easy for the manufacturer, but owner can end up with
a heavy boat. The transoms of such boats frequently end up under water, which is not a good thing
(drags and boat is sluggish). How a Transom should look can be seen in photo below of #1:
The good clearance is obvious. Best to be at or just above water level when boat is fully loaded. If a
transom is well under water, and particularly without anyone or gear on board, then check out inside
the boat, and this will usually have a glossy liner everywhere. Fine for power boats with plenty of
power, but not for sailboats. Liners also prevent easy access to the hull for inspection or important
maintenance, and this can become a major problem on older boats.
The original F-31 was once built in two versions, one without a liner (to my specs.) and one with a full
hull liner everywhere (much to my annoyance). The liner version was 1500lbs heavier and there were a
few red faces around. Needless to say only 6 were ever built and a set of very expensive internal liner
molds had to be thrown away. It takes more work to achieve a good interior finish without such liners,
but the boat is sooo... much better.
Thus great care was taken with the F-22 molded interior, to ensure it did not add extra weight by
lining or covering up the hull unnecessarily. It has thus taken a while, but has reduced weight as a
result, as well as speeding up assembly, which is how it should be. Our production rate can now
finally start to climb again, thankfully, after 3 months of what has been tough at times, with lots
of money going out but no progress payments coming in!
But while this was all going on, we also managed to finish and ship Hull #233

Wrapping it to put in the box
Now packed securely in the box and ready to go!
